The Clarifi COVID-19 test is one of only a few saliva tests authorized by the FDA for pooling samples for testing¹

Pooled testing helps save both time and money. Pools of up to 12 people are tested, a negative result means that everyone in the pool is presumed to be negative. A positive result means the samples need to be retested, this is called reflex testing. With our test, this reflex testing occurs immediately.  No waiting, no new samples required.  One swab does it all.    

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.
