And a third study, of 260 vaccinated health care workers in Chicago, found that overall, 43% were testing positive on rapid antigen tests five to 10 days after infection with omicron even though they felt well enough to return to work. A Boston University study revealed that just 17% of people were likely still contagious six days after their first positive tests. Home. Given the uncertainty, some experts have advised that test results at the end of an infection be viewed as just one potentially useful piece of information considered in concert with other factors, including a patients symptoms and immune status. So it's especially important to know when to take a COVID-19 rapid test, how to correctly interpret the results and when its OK to stop isolating even if youre still testing positive at 10 days and beyond. What Actually Just Happened With the Lab-Leak Theory?

Ideally, if you have access to enough tests, you wouldnt stop masking until you get two consecutive negative rapid test results taken 48 hours apart, Volk says. Additionally, if youre caring for an immunocompromised person, you probably want to test negative first. So why do some people test positive for the virus for 10 or 12 or even 14 days and are they still infectious after so long?

And 35% of them were still testing positive on day 10. In the most general terms, people will likely test positive on an at-home rapid COVID-19 test for about six to 10 days, Dr. Stephen Kissler, a postdoctoral fellow at the Harvard T.H. But people tend to be most infectious right at the beginning of their COVID-19 infection. But how to interpret your results isn't always obvious. "The best thing we have are these rapid antigen tests.". Preliminary data from scientists at Harvard and MIT shows that about 25% of symptomatic people with COVID-19 had virus that could be cultured after eight days after symptom onset or their first test. After 10 days, nobody in the study had infectious virus detectable on a PCR test. Symptoms typically appear just a few days after infection, with viral levels peaking less than five days after the pathogen first becomes detectable. A positive antigen test could essentially be picking up leftover viral "garbage," which can include "dead viruses, mangled viruses viruses that are 90% packed together but not really going to work," says Baird. According to Dr. K.C. According to a new analysis of people who sought repeat testing at a California site during the Omicron wave, an estimated 71 percent were antigen-positive four days after their symptoms appeared or after they first tested positive for the virus.
