Re: Sensitivity/specificity of ABT’s IgG* COVID-19 test

ABT serology test - blood based antibody test - for covid-19 is the best I have seen overall so far, 100% sensitivity and 99.5% specificity.

Just to be clear: The above figures—100% and 99.5%, respectively—are for individuals who are tested >=14 days after the disappearance of COVID-19 symptoms, or those who never had COVID-19 symptoms. Tests taken sooner than 14 days after the disappearance of symptoms would have lower sensitivity since it takes some time for IgG antibodies to be detectable.

This type of sensitivity and specificity is needed for large population with currently estimated prevalence.

Also for smaller defined populations such as employees at a given factory or office building.

*ABT’s IgM serology test is under development (#msg-155072306).
