Performance of these lfias is variablePublic health england has said 23.2% of the tests’ results are false negatives, and that their sensitivity was an average of 76.8% but this dropped to 57.5% when used in track.Rapid lateral flow tests for covid do not work well in people with no symptoms and should not on their own be used to allow people to go to work or school or to travel, experts have said.Rapid lateral flow tests help to find cases in people who may have no symptoms but are still infectious and can give the virus to others.

The british medical journal has warned that local authorities using lateral flow tests have not made the limitations clear to the public, including that they don’t identify all infections.The innova lfd has been tested the most extensively and has high specificity with acceptable sensitivity.This is dipped in a tube containing a solution to dilute the sample.We evaluated two lateral flow assays (lfa) systems:

We have flagged four lfds with the best performance characteristics from our assessments.
