Pooling samples involves mixing several samples together in a "batch" or pooled sample, then testing the pooled sample with a diagnostic test. This approach increases the number of individuals that can be tested using the same amount of resources.

What is pooling testing for COVID-19?

Pooling—sometimes referred to as pool testing or pooled testing—means combining the same type of specimen from several people and conducting one NAAT laboratory test on the combined pool of specimens to detect SARS-CoV-2, the virus that causes COVID-19.

Pooled tests that return positive results will require each specimen in the pool to be retested individually to determine which individual(s) are positive.

How do rapid Covid tests work?

A rapid COVID-19 test, also called an antigen test, detects proteins from the virus which causes COVID-19. This type of test is considered most accurate in those individuals who are experiencing symptoms of COVID-19.
