The molecular-based tests, considered the gold standard for detecting COVID , are a reliable tool but can take days to process, particularly as cases of the virus surge and people queue up for testing. Unlike less accurate antigen tests , which can be used at the point of care and deliver results within minutes, PCR tests typically require the use of lab equipment as well as technicians who are trained to process and interpret the results.
Clinics with their own onsite labs can process results more quickly. COVID testing has spawned a veritable cottage industry, with medically minded entrepreneurs stepping up to meet increased demand — often charging top dollar to expedite PCR test results.
Such services are undeniably convenient for those who can afford them. Yet they also underscore the ongoing constraints in COVID testing , which experts say is unfair for people of more modest means, and reflects wide gaps in insurance coverage for what's becoming a necessary tool for many people.
Clear19 Rapid Testing, founded in March in an effort to contain the virus before vaccines became available, offers the speedier molecular-based testing services for a premium. Clear19 uses a robotic lab that can process 90, specimens overnight, delivering test results to patients within 24 hours.

It is sent to a laboratory where a lab technician looks for genetic material of the virus using highly specialised equipment. The PCR tests are much better at finding very small amounts of the virus, especially early during an infection. So these are used primarily in people who have Covid symptoms.
It uses a long cotton bud, which takes a swab of the inside of your nose and the back of your throat. NHS Test and Trace figures show around 95 per cent of people get a result in 24 hours if they are tested under Pillar 1, which covers places like hospitals and outbreak spots. But around 60 per cent of those tested at large drive-through centres, under Pillar 2, get their result back in 24 hours. For example, results may take longer to come back during very busy periods or peaks of waves because labs are swamped with tests.
Usually the result is sent to you via text or email when it's ready. If you have the NHS Covid app, the result might come to you that way. So if there's a gap of weeks or months in between your positive tests, you might be dealing with a whole new infection. And the use of at-home COVID antiviral medications, like Paxlovid, may add another wrinkle: Some people are reporting that, after their symptoms resolve with treatment, the symptoms then return in a Paxlovid "rebound," Dr.
Along with the return of COVID symptoms, it's also possible to get another positive test — even if you tested negative within a few days, the CDC noted. So, if you're trying to do your due diligence and testing at home frequently during your COVID infection, know that it's possible for you to see positive results for a while.
What to know about coronavirus reinfections. As long as you continue to test positive on a rapid at-home test, you should still consider yourself potentially contagious, Kissler said.
Some had positive viral cultures for as long as 12 days after the onset of their symptoms, suggesting they could still be contagious. When you get to that point, you have to start weighing your options about whether or not you need to start interacting with other people and how to do so as safely as possible. It is safest to continue to isolate until you no longer test positive, the experts stressed. But if you must interact with others before you test negative, you should take care to wear a high-quality mask, stay physically distanced when you can and avoid spending time in enclosed spaces around other people.
But that may not be feasible for everyone. And taking the CDC guidelines into account, it's not unreasonable to gradually leave isolation after 10 days — even if you're still testing positive on a rapid test, Kissler said. That's especially true if you're fully vaccinated, any symptoms you developed have resolved, and you continue to take as many other precautions as you can until you get a negative result.
