LA-area COVID test specs

I’ve been getting periodic current-infection COVID tests at Curative sites in Los Angeles for several months now. Today I learned that their test has poor specificity for asymptomatic individuals. I also took their new antibody test.

The new antibody test was developed in a joint effort between Curative and OraSure.1

Test Sensitivity/+Agreement Specificity/-Agreement
Curative RT-PCR2 (asymptomatic) 0/3 82.4%
Curative/OraSure COVID-19 Antibody 90.9% 100%

The FDA recently (Jan 4, 2021) issued guidance that the curative RT-PCR oral swab test negative result may not be accurate in asymptomatic individuals.4
