Which COVID-19 Rapid Antigen Test is the most accurate?
If you would like to understand the accuracy of your COVID-19 rapid antigen test kit, you will need to know what do Sensitivity (PPA) & Specificity (NPA) mean.
What are Sensitivity (PPA) and Specificity (NPA)?
Sensitivity measures the ability of a test to detect the condition when it is present. It is the probability that the test result is positive when the condition is present.
Specificity measures the ability of a test to detect the absence of the condition when it is not present. It is the probability that the test result is negative when the condition is absent.
