Amid a record-breaking COVID-19 spike, testing guidance is still confusing, and still changing with the arrival of the omicron variant. The Herald asked doctors for their best advice and here’s what they said:
PCR Tests: These tests, also called molecular tests, are still considered the “gold standard” because they’re the most sensitive. They also require a longer turnaround time, usually one to three days. Dr. Todd Ellerin, director of infectious diseases at South Shore Health, added that PCR tests may also be better at detecting the new omicron variant.
PCR tests are most useful for a more definitive COVID result, especially if it’s positive, and to confirm the results of a rapid test. Dr. Davidson Hamer, a professor at the BU School of Public Health, added that these tests are effective if taken a day or two before a gathering if one can get the results in time and not get exposed in the interim. He also advised taking a PCR test if you’re asymptomatic but are around five days out from a known COVID exposure.
Rapid tests: These tests, also known as antigen tests, are available over the counter and are best used immediately before an event, and could even be given on the doorstep of a party, for example. These tests are also given for travelers to the U.S., who need to test negative the day before coming into the country.
Hamer recommended that those with flu-like symptoms start by taking the more readily available rapid tests. A symptomatic person who has COVID-19 will pretty reliably get a positive test from a rapid test, he said.
