This is why it seems to take so long for a rapid test to turn positive. At the same time, millions more at-home rapid tests are becoming available. You can order free rapid tests from the government here. While PCR tests are still the gold standard, they can take a few days to a week or more to produce results as understaffed labs struggle to keep up with demand. Rapid tests are a welcome addition because they can give results in minutes. But beware of the dreaded false negative.
It happened to Georgia resident and economist Christopher Cunningham, 46, whose year-old daughter had a positive result on a PCR test on Jan. Her rapid tests, however, always came back negative.
The same thing happened to his 9-year-old daughter. Both were vaccinated. Emily Landon, an infectious disease expert and associate professor of medicine at the University of Chicago Medicine. Rapid COVID tests, also called antigen tests, work by detecting bits of proteins on the surface of the coronavirus.
Your vaccination status can influence this process, too, but more on that later. This relatively high threshold correlates with contagiousness, experts say.
You need to stay home. You can think of your viral load like a mountain, says Dr. The window varies widely, too; it could last three days, six days, or even a week or more for some people because everyone clears the virus from their system at their own pace, she said.
In what seems like another layer of complexity, the intensity of that second line on your rapid test is likely an indicator of infectiousness, experts say. The darker it is and the quicker it appears within the minute wait period , the higher your viral load and risk of spreading the virus, and vice versa. If you have coronavirus symptoms and test negative on a rapid test, Landon suggests you confirm that result with a PCR test or take another rapid within the next two days.
On the other hand, PCR tests are much more sensitive. They look for the tiniest fragments of coronavirus genetic material by multiplying the virus over a million times until it becomes detectable, Blaser told BuzzFeed News. The CDC says you can end isolation after five days if you have not had a fever for 24 hours and other symptoms are resolving. After that, they suggest caution for an additional five days, including mask-wearing, avoiding travel, and staying away from people who are at high risk.
You don't need to have a negative result to end isolation, but if you do want to take a rapid antigen test, they suggest testing near the end of the five-day period when you have been fever-free for 24 hours without taking fever-reducing medicine. If it's still positive, you should isolate for the full 10 days. Having symptoms can be a bonus, however, because they can help you decide when to take your rapid test to ensure you get the most accurate results possible. Back when the never-before-seen COVID-causing virus started raging, people would experience symptoms much later in an infection compared to now.
Landon said vaccinated folks can expect to see a positive rapid test result one to three days after symptoms start. However, rapid tests may turn positive earlier in some unvaccinated people. In general, vaccinated people with healthy immune systems will have symptoms that are milder and less likely to lead to hospitalization and death than people who are unvaccinated.
In addition to poor timing, the accuracy of your rapid test depends on how well you follow instructions. If you swab your nose incorrectly or drop too much of the liquid onto the test, you can end up with a false negative. All FDA-authorized rapid tests require nasal swabs, but some people have posted on TikTok and other social media platforms saying a throat and nasal swab combination turned positive before a nasal swab alone.
One non-peer-reviewed study released Jan. Experts agree: You should follow the instructions when performing a rapid test and avoid swabbing just your throat. After five days of throat pain, neither my two rapid nor two PCR tests came back positive, even though my COVID-carrying roommates and I had shared all living spaces without precautions.
