The U.S. Food and Drug Administration (FDA) has authorized the SalivaDirect PCR COVID-19 test created by the Yale School of Public Health for use with pooled saliva samples.
Pooled testing allows labs to combine saliva samples from multiple individuals into a single tube and process the batch as a single test. This approach maintains the clinical sensitivity associated with the real-time reverse transcription polymerase chain reaction tests — the gold standard for detecting SARS-CoV-2, the virus that causes COVID-19 — and gives labs the ability to process the tests far more quickly. The FDA authorizes Yale-designated laboratories to use the SalivaDirect test to pool as many as five samples at a time for SARS-CoV-2 testing.
Better to have nothing in the meantime I guess! In the meantime, only a handful of pooled spit tests have been approved.
