The RT-PCR test apparently has a very high false negative rate; I've read up to 30% or even 40%.
Also, they had all the other symptoms as well including fever and shortness of breath. One arrived in India with respiratory distress. The other fell ill a week after visiting a Covid hotspot -- Mumbai -- which he managed to visit despite a travel ban because he was a hotshot politician.
- ksk 6y agoWhere did you read that? Was it a reputable source that cited peer-reviewed data? We use RT-PCR every single day at our company (vaccine development) and we couldn't do our jobs if it performed so abysmally. The RT-PCR is the gold standard when it comes to detection.

I meant clinical sensitivity for RT-PCR for SARS-CoV-2 for samples drawn from throat swabs, specifically. I know that my local hospital is only taking throat swabs, not nasal swabs; and all the press photos I've seen for testing in India is of throat swabs.
- ksk 6y agoWell, then that's not really the RT-PCR that's at fault, its the way the disease presents itself, that makes it difficult to find a reliable point of sampling. Although, I can see how in casual conversation one might say that the RT-PCR test isn't reliable.
