Mohammad Hafeez gets his own COVID-19 test done - and its negative! Are PCB tests to be trusted?

[Junaids]

I was rather hoping Hafeez would test positive until September.

Given the close contact of Imran and Naseem, I’ve been worried that Naseem has returned a false negative TBH.

 

[MenInG]

This from a well-known doctor:

No surprises at all re Hafeez . Again shows incompetence of PCB medical panel. Those players that's don't have the resources or contacts like Hafeez - what happens to them.

The biggest issue here is that PCB shouldn’t have released players information without their consent and should have done repeat testing and contact tracing to be sure and only then release information if player is happy for them to do so.

Irrespective of cricket and our likings, we shouldn't hope for anyone's bad.

It's a weird scenario now. The question is whom to believe and where exactly has the mistake been happened in testing because the gap in number of days between the testing done by PCB and by his personal doctor is minimal.

Which is why leaving testing so late was a bad idea.

 

[AAli98]

That’s why they call him professor, this leech ain’t going anywhere anytime soon.

 

[shah_1]

Every other player needs to get tested as well after this farce

 

[Mueez]

Don’t trust all these tests that are happening in Pakistan...

 

[shah_1]

What a farce by PCB

ECB must be thinking that we are dealing with bunch of jokers. Should have started testing around 10th june, get retested after every 4 days

 

[cricketjoshila]

Let him be tested again in few days by pcb and his own lab with same sample.

 

[shah_1]

You have to be tested negative 2 times to be all clear once you are tested positive.

 

[the eslah]

I think not PCB but the whole testing kits provided through charity are fake or second class kits. PCB should answer this serious quora?

 

[the eslah]

[MENTION=132916]Junaids[/MENTION] u r right. They were Roaming everywhere for nothing but for fun and Dawat but they are negative and hafeez,wahab +ve. Just cant beleive this

 

[Hawkeye]

Knew it all along that PCB and govt testing is pathetic. Lots of false positives and inaccurate results.
[MENTION=132855]Arsal_AK[/MENTION] here's your proof.

Unprofessional acts by the PCB the last few days. They should've tested from both govt and private labs.

Before going all out on the media!

 

[Jin Chacha]

Not an expert but what I had heard from my doctor friends was that a false negative is much much more likely than a false positive in the pcr test. Unless there is some cross contamination between samples, there is no way the PCR will detect the virus if it is not there. A false negative can, however, result from some technical or human error. In that case it is much more likely that it is the second test which Hafeez had done privately is wrong rather than the one that PCB did.

Can any of our resident doctors can comment on this?

 

[the eslah]

Can we trust PCB's medical board after hafeez jibe?

Cricket: @TheRealPCB media on monday released a report on update of players Testing for covid-19 in lahore and karachi. According to the Reports 7 players were covid positive namely Fakhar,hafeez,hasnian,imran khan,kashif bhatti,M Rizwan and wahab riaz while 16 players reported negative. After the case questions raised on social media about players wheter they are taking this seriously or not? Are they serious about ENGLAND tour etc but very few peoples Question PCB testing panel and system. The very next day mohd hafeez(who was shown covid +ve acc. To PCB) Along with family visited testing Lab in personal capacity and the result was surprising. The result came negative, Yes u read in right NEGATIVE and none of his family member came corona positive. The cricketer took to social media to share the good news with his fans_____ after that now many are doubting Testing kits used by PCB. What is your take on this?
1.Testing kits used by PCB is not accurate.
2.It was just a mistake by chance.
3.testing kit in pakistan in not accurate
4.OR ???

 

[Afhan Ali]

Another success for Mr Waseem " I love my country " Khan.

He is same as Ijaz Butt, Zaka Ashraf etc

 

[SensiblePakFan]

Still a month away from the tour. Everybody will be fine by then.

 

[Afhan Ali]

Here in our city most people test themselves from private lab, people do not trust the government labs. Same should be the case for players, they should have been test it 2 times before coming to media.

 

[Afhan Ali]

In which field PCB is doing right things?

Almost nowhere

 

[Mamoon]

Another example of the professionalism of Mani and Wasim. What will we do without these two high performance stalwarts.

Not a doctor but this is true

Hafeez has to test negative again to be sure

 

[Hawkeye]

As a doc I guess you should know that probability of a false negative is much higher than a false positive.

 

[Majid Khan]

How does anyone know which of the two tests had the wrong result?

It’s possible there was an error on PCB arranged test , but It will be interesting if we now see other players coming out with their negative tests also, now that one player has shown the way.

 

[Mamoon]

It is a complete circus.

First, the allowed the players to train together with no regard for SOPs.

Second, they threw the players under the bus and absolved themselves from all blame.

Third, it appears that some of the test results are dodgy, which means that it is possible that some players are infected but PCB thinks they are not, and that means that more and more players will get infected.

I cannot comment on why the tests came out wrong and where the lapse happened, since this is not my domain, but ultimately, you have to point fingers at PCB. Wherever the lapse happened, it is because of PCB’s incompetence.

Mani and Wasim are only good for creating new fancy positions and throwing money at them.

 

[Mamoon]

As a doc I guess you should know that probability of a false negative is much higher than a false positive.

Yes, but false positive results also happen. Besides, as I explained, this is not my domain so I cannot comment on where the lapse happened during the testing. Could be multiple factors. Anyway, it is PCB’s fault.

 

[MenInG]

Yes, but false positive results also happen. Besides, as I explained, this is not my domain so I cannot comment on where the lapse happened during the testing. Could be multiple factors. Anyway, it is PCB’s fault.

Pretty poor this.

You state you dont know the facts and its not your domain but have no qualms in blaming PCB.

 

[DeadlyVenom]

Hafeez has never trusted a test in his life lol. Even when banned for chucking there was always a fault with the test.

He is truly a tenacious and determined man.

Test again to be sure.

It's happening worldwide. I already explained in the other post as to why we get false positives. This is why PCB said they will test again.

False negatives occur too. This could be one. Take this with a grain of salt, it's anecdotal, but I haven't heard good things about Chugtai Labs regarding their testing methodology.

PCB's handling is another matter. But I don't think they did any wrong, the same is happening all over the world. And it would have gotten out anyway as you know, they did good by staying ahead of the circus that would have followed.

Hafeez should be considered positive untill he is tested again. Two negative tests by PCB should give him the clear.

 

[Arsal_AK]

Yes, but false positive results also happen. Besides, as I explained, this is not my domain so I cannot comment on where the lapse happened during the testing. Could be multiple factors. Anyway, it is PCB’s fault.

Not its not. What were they supposed to do? Say the test was negative when it's positive?

He could still very well be positive. The PCB should ignore this test.

 

[Abdullah719]

I don't know where PCB had the tests done from but I'm not really hearing positive things about Chughtai Lab.

Whichever is the most reputable institution for this should be the one where tests are done.

 

[Arsal_AK]

It's very unlikely that you could test positive unless you have the virus.

But it's very easy to test negative despite having the virus. The swab has to be taken as perfectly as possible, small mistake like not going deep enough or using the wrong angle and you could end up getting a negative result when you have the virus.

Antibody test should give a better picture along with further PCR.

But, Hafeez should be considered positive as he most likely is or was.

 

[MenInG]

And thanks Mohammad Hafeez - by not going to PCB privately he has put the whole tour in jeopardy.

 

[Arsal_AK]

I don't know where PCB had the tests done from but I'm not really hearing positive things about Chughtai Lab.

This is true. The tweets under that tweet are saying the same thing.

This test result should hold no value whatsoever to the PCB even if the lab was not under question. A positive PCR is much less likely to be wrong, than a negative one, I hope they know that.

 

[Usman]

I think we need an explanation from the PCB here.

It is a widely known fact that up to 30% of negative test results for Covid are false negatives (at least here in the UK). So it's possible Hafeez's result is a false negative.

But this is the first time I am hearing of the possibility of a false positive!

I must say it is highly suspicious that 10 players have tested positive so far and that they are all asymptomatic. Hafeez may be onto something here about the credibility of PCB testing.

 

[Majid Khan]

And thanks Mohammad Hafeez - by not going to PCB privately he has put the whole tour in jeopardy.

Exactly this , he’s put a question mark over the accuracy of the PCB testing and made a mockery of the whole thing by going private and then publishing results on twitter. He’s entitled to get a second opinion , that’s fair enough, but surely he should have discussed with PCB confidentially and given them a chance to deal with situation and handle any comms. Instead Hafeez has yet again put his own position and selection for the team ahead of everything else.

 

[Mamoon]

Wasim Khan threw the players under the bus in ruthless fashion.

Therefore, Hafeez was under no obligation to keep this matter private and not raise question marks on PCB’s credibility publicly.

He did the right thing. PCB had it coming.

 

[Mamoon]

No government/institution throws its players/public under the bus. This seems to be a Pakistani speciality.

“Well we told our people to be careful but they didn’t listen so it is not our problem.”

Sorry but that is nonsense. This is called shying away from responsibility and accountability.

Several arsenal players tested positive after their match against Man City, but the club did not blame the players.

 

[Junaids]

And thanks Mohammad Hafeez - by not going to PCB privately he has put the whole tour in jeopardy.

Selfish as ever.

He’s never had much of a brain, and clearly doesn’t see how much harm this does to the PCB.

It's very unlikely that you could test positive unless you have the virus.

But it's very easy to test negative despite having the virus. The swab has to be taken as perfectly as possible, small mistake like not going deep enough or using the wrong angle and you could end up getting a negative result when you have the virus.

But, Hafeez should be considered positive as he most likely is or was.

Yes.

Overwhelmingly likely that the second one is a False Negative.

Since the test results are unreliable, PCB should not have disclosed the names of the players. This would have prevented Hafeez-like controversies.

But this would require a competent board which PCB clearly is not. We have heard a lot about the so-called professionalism of PCB under the two UK imports, but so far we have not seen an ounce of professionalism when it matters.

Hafeez’s reaction is justified. Firstly, PCB did the wrong thing by revealing the names publicly. The whole country does not need to know that Hafeez and others have COVID.

Secondly, after wrongly publicizing the names, PCB threw the players under the bus by categorically blaming them.

Thus, this outburst was expected. Hafeez is under no obligation to respect PCB’s reputation when PCB did not care about the reputation and the privacy of the players.

How are the test results unreliable? Based on what I've heard from doctors, a positive test means that a person is almost certain to have the virus (i.e., false positive isn't really a thing). Whereas a negative test has a 30% chance of being a false negative.

Can any of the doctors here confirm? [MENTION=140234]DRsohail[/MENTION], [MENTION=128087]last_knight[/MENTION], [MENTION=76058]cricketjoshila[/MENTION], etc. [MENTION=131701]Mamoon[/MENTION] you're welcome too if you can answer this objectively...

What they should have done is to have a 2nd test to confirm the 1st one but if Hafeez is positive, then people do need to know in case they came in contact with him. Are you saying the privacy of cricketers is more important than public protection?

 

[Bewal Express]

Whilst I'm no fan of Hafeez, I disagree because PCB went public with his result, so why shouldn't he? It's PCB who are putting the whole tour in jeopardy with their incompetence.

And if Hafeezs own test turns out to be false then this should be the end of his career. And if the company that did the original test used fake test kits, they shouldnt be paid and barred from doing any more work for the PCB and the govt

You cannot disclose someone's health without their consent. Secondly, what makes it worse is the fact that the test results disclosed by PCB cannot be trusted.

Lastly, as Mamoon mentioned, you cannot divert the blame from yourself to the players (like Wasim Khan and Mani have done).

Again, I don't see how the tests can't be trusted when by all accounts there is no such thing as a false positive. If a person tests positive then 99.9% they have the virus. Unless the PCB has used some alien testing method.

There is no exact science to Covid Testing. It could well be that when the original sample was drawn, it was during later stages of the infection, whereas when the second sample was drawn, the infection had passed.

I highly doubt any entity is using 'fake kits.' It takes A) Sample drawing, B) Sample storage, C) Running of PCR test on a diagnostic kit, and D) interpretation of the result by a medical professional; all to come up with an assessment.

 

[MenInG]

Former Pakistan cricketer Rashid Latif lashed out at Pakistan Cricket Board (PCB) and its players, saying their unprofessional approach during practice led to the positive cases of the novel coronavirus in the squad.

PCB on Tuesday said 7 more players after the initial batch of 3 players tested positive for Covid-19 following tests conducted in Lahore on Monday in the lead up to the England tour.

A total of 10 players were found to be tested positive for the novel coronavirus but Mohammad Hafeez on Wednesday said he tested negative for the virus when he got himself tested for 2nd opinion in personal capacity.

Rashid Latif, who played 37 Tests and 166 ODIs, said he saw players who tested positive for Covid-19 practicing outdoors together and sensed there would be a problem in the wake of the pandemic.

"Players who have tested positive were practising outside together, so there was bound to be a problem.
Unprofessional approach from PCB and players is to blame for these positive COVID-19 tests," Latif said in a video posted on his YouTube channel.

"I also went to the ground for one day, but I maintained my distance with Rohail Nazir. You have to follow the protocols and keep distance," he added.

Pakistan announced a 29-member squad for the England tour wherein they will play 3 Tests and a T20I series from August.

Initially, 3 players Haider Ali, Haris Rauf and Shadab Khan were revealed to have tested positive for Covid-19 on Monday. In the second batch of results that were published by the PCB on Tuesday, further 7 names Fakhar Zaman, Imran Khan, Kashif Bhatti, Mohammad Hafeez, Mohammad Hasnain, Mohammad Rizwan and Wahab Riaz were found to be tested positive for Covid-19 along with support staff.

Despite the positive Covid-19 test results, Pakistan are confident of touring England this summer. PCB CEO Wasim Khan said the squad, barring the Covid-19 positive players will leave for England as scheduled on June 28 from Lahore.

PCB said it will test players once again on June 25 in bio-secure environment in Lahore and the ones who return negative results will be able to fly to England.

Players who have tested positive for the virus and the ones who may test positive on June 25 will be asked to isolate at their homes and be monitored strictly by the PCB medical team.

They will be allowed to join the squad in England at a later date after the completion of the mandatory isolation period and subsequent negative results in 2 Covid-19 tests.

Understood, but before you unveil the results to the world, at least verify the reliability of the test results. PCB's lack of professionalism is coming into play again here and it cannot be excused even in the slightest.

That is def a possibility but the PCB need to do another test, and if that is positive, then Hafeez needs to be banned, or if its negative the company that is doing the PCB tests shouldnt be paid and banned from doing more tests.

 

[topspin]

PCB are the admin body - he should have asked PCB about the tests - only reason he announced it was to embarrass PCB and gain some friends in the outside world.

I agree with this. We all know what Hafeez is like, but unfortunately PCB needed to be put in their place by someone for the way they've approached this.

As soon as they tested positive, isolate them and verify. Maybe the PCB trusts the tests and was advised that it didn't need to do it. As someone pointed the chance of a false positive is statistically negligible.

 

[topspin]

Why can't the test results be trusted?

I think Hafeez's second test result makes that clear and not to forget PCB's track record of incompetence and lack of professionalism.

Correct.

Hafeez’ positive test had 99.9% accuracy.

His negative test had 60-70% accuracy.

 

[MenInG]

Understood, but before you unveil the results to the world, at least verify the reliability of the test results. PCB's lack of professionalism is coming into play again here and it cannot be excused even in the slightest.

How in your considered opinion can PCB verify the results? The results came from a lab so why would anyone not trust them?

 

[Titan24]

No test in the world currently is 100% accurate. I thought even the players who had positive test result were going to be tested again as well.

 

[Kroll]

Man, this is turning into such a circus, what an embarrassment!

Hafeez should be kicked out for good due to insubordination.

 

[MenInG]

Just for your information -

Rizwan and Hasnain will not be getting themselves retested and are going by what PCB is asking them to do.

Tests were done at various centers run by Shaukat Khanum Hospital.

 

[HitWicket]

On Twitter after his PCB test he says he immediately isolated himself from his family then on today twitter post he says after getting tested by the PCB he went to go get another test done with his family, sounds pretty contradictory to me.

 

[Thunderbolt14]

Don’t trust all these tests that are happening in Pakistan...

Chughtai labs in general is very reputable, to be fair. But yeah, I’m a bit confused.

 

[Thunderbolt14]

Take this with a grain of salt, it's anecdotal, but I haven't heard good things about Chugtai Labs regarding their testing methodology.

Just saw this, can you elaborate?

True, false negative are a thing and that's why a negative result has to be repeated atleast a couple of times after the mandatory two weeks period. They are also much more likely to occur.

What's more the probability of getting a false negative goes up with time.

You are right, false positives are extremely rare not really a worry expect in cases where the extreme sensitivity of the test picks up dead viral fragments.

Both Hafeez and PCB should take the first positive test as the correct one. His second test is most probably a false negative. He should be in quarantine for a week atleast after which a couple of negative tests should give the green light for having cleared the virus. This should be combined with an antibody test, which should confirm that he had the virus.

There was an article in nature that went into detail but I can't find it. I'll link a paper from NEJM which says the same thing.

https://www.nejm.org/doi/full/10.1056/NEJMp2015897

Yang et al. described 213 patients hospitalized with Covid-19, of whom 37 were critically ill.2 They collected 205 throat swabs, 490 nasal swabs, and 142 sputum samples (median, 3 per patient) and used an RT-PCR test approved by the Chinese regulator. In days 1 through 7 after onset of illness, 11% of sputum, 27% of nasal, and 40% of throat samples were deemed falsely negative.

 

[coy0607]

There's a lot of tests out there with very little data on their validity - leading to a higher percentage of false positive and false negatives than would otherwise be acceptable. That may be what is happening in this situation, rather than some elaborate ploy against an individual

But to answer your question - NO, the PCB can't be trusted. But neither can Hafeez

True, false negative are a thing and that's why a negative result has to be repeated atleast a couple of times after the mandatory two weeks period. They are also much more likely to occur.

What's more the probability of getting a false negative goes up with time.

You are right, false positives are extremely rare not really a worry expect in cases where the extreme sensitivity of the test picks up dead viral fragments.

Both Hafeez and PCB should take the first positive test as the correct one. His second test is most probably a false negative. He should be in quarantine for a week atleast after which a couple of negative tests should give the green light for having cleared the virus. This should be combined with an antibody test, which should confirm that he had the virus.

There was an article in nature that went into detail but I can't find it. I'll link a paper from NEJM which says the same thing.

Agree with your views overall but you have to also consider the possibility of human error taking place during the testing process , such as the sample taken for some other player being mislabelled as belonging to Hafeez , and an erroneous positive result being given to the candidate.

Either way the sensible thing would have been for Hafeez to have quarantined and if he had any uncertainty then he should have consulted his employers, PCB, for their assistance and recommendation on further testing - rather than directly taking the private test route and publishing results on social media to cause further embarrassment.

I don't know where PCB had the tests done from but I'm not really hearing positive things about Chughtai Lab.

Whichever is the most reputable institution for this should be the one where tests are done.

Same here. I don't know what type of tests they are using.

 

[the Great Khan]

im sorry but Hafeez is an $$%$^. Why is he single highhandedly trying to undermine the testing process? who made him an expert? He needs to shut up and quarantine. End of. there is nothing else for him to do here.

Same here. I don't know what type of tests they are using.

It looks like PCB's tests were done at Shaukat Khanum labs.

His Covid tests are like his bowling action tests

No test in the world currently is 100% accurate. I thought even the players who had positive test result were going to be tested again as well.

Wasim Khan said this atleast half a dozen times in yday's presser that players who have tested +ve will be tested again and if it turns out -ve twice within 48 hour span, they will then depart to England via a commercial flight

Exactly.

Hafeez should get taken to task and it’s about time he faced PCB disciplinary hearing on this issue - what ever the accuracy of his test result , at the end of the day he’s an employee of the PCB and if the employers have arranged a medical test and communicated publically that an employee is unfit for work, he needs to quarantine and they are willing to support him with further testing as they have said indeed for all players who have tested positive - is it right for an employee then to arrange for a private test without any consent from his employer , and then publish his private test report to cause embarrassment to his employer and indeed the national cricket team. For what, just to try to guarantee his flight on the plane to go to England?

Ideally it would have fit perfectly for him to travel later(around mid July) rather than being there 2 months before the T20Is are to be played, but looks like the self claimed professor wants to make a dramatic comeback into Tests as well, also said this during presser that he's ready to play Tests 'if needed'. Can't really understand why PCB/selectors are adamant at selecting him despite him being a mediocre player at best and keeping bringing the organisation into disrepute every now and then

 

[topspin]

How in your considered opinion can PCB verify the results? The results came from a lab so why would anyone not trust them?

It's all about due diligence, which ofc is a very alien concept for the PCB.

True, that is what I remembered so this personal initiative by Hafeez doesnt make much sense as he only had to wait for PCB to follow their procedure.

I was rather hoping Hafeez would test positive until September.

Given the close contact of Imran and Naseem, I’ve been worried that Naseem has returned a false negative TBH.

Wow what a guy wanting someone to be positive are you even human
