Researchers at the University of Washington in Seattle have created a new test for COVID-19 they say combines the speed of an over-the-counter antigen test with the accuracy of a PCR test. The Harmony ...

Rapid urinary antigen testing is widely used for pneumonia diagnosis, yet it often lacks the consistency and traceability required in today’s clinical laboratories. This webinar explores how fully ...

Polymerase chain reaction (PCR) and rapid (antigen) tests for COVID-19 both involve taking a swab. Results for a PCR test take longer, as it needs to go to a laboratory. It is more costly but tends to ...

Researchers from Johns Hopkins Medicine and collaborating institutions report that a rapid antigen test for SARS-CoV-2—the virus that causes COVID-19—proved highly accurate when compared to the ...

A polymerase chain reaction (PCR) test detects genetic material from a pathogen or abnormal cell sample. Ways of collecting samples include a nasal swab, a saliva swab, or taking a sample of blood.

What does it mean if a person’s rapid antigen test result comes back positive after five days of isolation due to COVID-19? According to the experts, that person is most likely still carrying a viral ...

Yes, the experts agree. If you performed the test correctly, a faint line on a COVID test is still a positive result. "Any ...
