COVID testing FAQs

The most sensitive COVID saliva test on the market.

The FDA requires that manufacturers measure the sensitivity of their test against a standardized SARS-CoV-2 Reference Panel.

The measure of this test sensitivity is known as Limit of Detection or LOD. High LODs will miss more infected patients and result in more false negatives.

LOD is reported as nucleic acid amplification test-detectable units (NDU) per milliliter or NDU/mL.

Our COVID-19 PCR Saliva Test has an LOD of 600 NDU/mL, currently making it the most sensitive saliva test on the market.1
