Accuracy figures for selected COVID-19 antibody tests U.S. 2020

Siemens Healthineers' Atellica IM Sars-CoV-2 Total (COV2T) test has a sensitivity of 100 percent and a specificity of 99.8 percent. Specificity is the ability of a test to give a true negative test, that means that the person has not been exposed to SARS-CoV-2 and therefore not developed antibodies.

Supplementary notes

* Commercial tests only. Covid-19 antibody tests with EUAs yet to be independently evaluated.
Sensitivity - Correctly identify someone who has been exposed to SARS-CoV-2 and truly has developed antibodies to it (true positive rate).
Specificity - Rule out someone who has not been exposed to the virus and has not developed antibodies (true negative rate).
PPV & NPV = positive & negative predictive values. PPV and NPV calculated at 5% prevalence.
