Rapid Covid Test False Positive Rate. 52% (1561/3060) of all positive cases identified during may 2021 in. The kits can report false positives when wells in the assay reagent tray that contain positive samples overflow and contaminate neighboring specimens.
However, one of the major downsides of these tests is their high rate of false negative results (having a negative test result even. 1 at relatively low population. In children with symptoms, diagnostic sensitivity and specificity were 71.8% and 98.7%, respectively, and in those without symptoms, sensitivity and specificity were 56.2% and 98.6%, respectively.
In Effect, This Means That If 100 People Had Covid And Were Infected With The Omicron Variant, Only 37 Of Them Would Get A Positive Result And The Others Would Get A Falsely Negative Result.

This represents 42 per cent of the positive test results in the study. Of those that tested positive during the rapid antigen test, researchers confirmed that 462 were false positives. Its analysis suggested that the sensitivity of rapid tests to detect the omicron variant was 37 percent, compared to 81 percent for delta.
