What State governments are doing wrong in India?

They are sending patient / case information to ICMR / testing labs along with samples.

That's why many #FalsePositive is coming in samples of minorities and #FalseNegatives coming in others.

Identity samples by barcodes please.

No personal information is supposed to go to testing labs (in any ethically correct scientific examination ).

Samples should be identified by an unique id, generated by Nodal authority of the state. The state should then perform epidemiological investigations.

For tainting a negative sample to a positive sample, all a bad and bigoted tester has to do is..

Pipette.

Yes, science has its pitfalls too.

How do I know this scam..

Well because ICMR is giving the details of Markaz cases when briefing press.

They shouldn't have the personal information of samples.

That bit has to be done by state govts, who has to determine clusters.

Give me one known positive Markaz sample and give me samples of Trump, Biden, Modi, Shah..

I can make all of them coronavirus positive and belonging to Markaz cluster in less than 2 minutes.
