the reliability of antigenic tests questioned

Within weeks, antigen testing has become one of the new essential tools of the sanitary arsenal against Covid-19, in particular by its speed. The analysis is delivered between 15 and 20 minutes. The success is such that we can find 80 different tests on the French market. But not all are created equal. This is the conclusion of a study conducted by theAPHP.

The researchers analyzed nine tests and for six of them, “the sensitivity of the tests […] was considered insufficient for use in the context of diagnosis or screening for Covid-19 infection“, can we read in the report. In other words, with these tests, a significant number of people positive for the virus fall through the cracks of the net. The risk is to encounter false negatives. We will be good for all the subjects who have a very important virus production, on the other hand, for the subjects who have a lower virus production and who remain contagious, we can rater“; explains professor and virologist Jean-Michel Pawlotsky.
