BinaxNOW tests are still good and considered effective.
BinaxNOW tests are good for testing COVID-19 variants such as Omicron and it's subvariants as they target a different part of the virus, "nucleocapsid" than the changing spike protein.
The date on the box for the BinaxNOW tests is often extended.
For best accuracy with the BinaxNOW tests, perform multiple tests over a couple of days, especially if your symptoms are mild or you're unsure of exposure.
Antigen tests, such as the BinaxNOW COVID-19 Antigen Self Test, detect proteins from the virus.
Due to the lower sensitivity of antigen tests, there is a higher chance this test will give you a false negative result when you have COVID-19 than a molecular test would.
BinaxNOW COVID-19/Flu A&B detects multiple COVID-19 variants and Flu strains.
There are two types of COVID-19 tests: the polymerase chain reaction (PCR) test and the antigen test, known as the rapid test.
Both tests require a sample from the patient, usually a nasal swab.
Most at-home rapid tests can still detect this variant.
However, if your first test is negative but symptoms persist, repeat testing after 24–48 hours is recommended.
