Nasal Swab Performance
Nasal swab samples have 97% sensitivity and 99% specificity. This is the recommended method for the highest accuracy.
Saliva Sample Performance
Saliva samples offer slightly lower sensitivity of 90% and 99% specificity. If high sensitivity is your goal with Metrix, we suggest you use a nasal swab.
