Yes, this is actually a photo of a negative Covid test result, but it’s still helpful. How will you know if the test is positive, though? Here are some photos of positive Covid test results to help you read your result. If it comes back as a false negative at that point, Denny says you’re “most likely not able to transmit to others on that day.” However, don’t trust the negative result right away, wait another day or two and take another test (and possibly another a day or so after that one). Your best bet is to take a test as soon as you start experiencing symptoms, or once you know you’ve been exposed. ![]() “When an individual turns positive is related to the specific variant, because they have different incubation periods, and how much exposure someone has had” Denny explains. ![]() As for when to take an at-home Covid test, there is no perfect answer. “One of the biggest variables to all testing is to have a good quality swab process,” says Denny, so it’s extremely important to read and follow the directions that come in your at-home Covid test so that you can get an accurate result. However, if you have a positive result on either a rapid antigen or molecular test, you should trust that result, because false positives are very, very rare, says Denny. It’s worth noting that Covid self-tests performed at home are not as reliable as those performed in a laboratory setting. However, that accuracy and speed come with a price tag, and antigen tests are still an incredibly useful tool for detecting contagious Covid infection. Molecular tests tend to be more sensitive, so they can detect Covid infection earlier than antigen tests can - from a few hours up to a few days faster. Rapid antigen tests tend to detect Covid when you're carrying a lot of the virus. There are two types of Covid-19 diagnostic tests that are FDA-approved for home testing: Rapid antigen tests and molecular tests. “ can be countered by repeat testing over a few days,” he explains, “Repeated negatives increase the certainty of a true negative.” Antigen versus PCR: Different types of Covid tests available for at-home testing The best way to ensure that a negative result is correct is to keep testing, Denny says. “Yes, but as with all testing platforms they have advantages/disadvantages,” says Thomas Denny, a Professor in Medicine at the Duke Human Vaccine Institute at Duke University School of Medicine. Given that the virus itself is so new and still has so many unknowns, it’s fair to wonder whether or not at-home Covid tests are reliable. These tests are incredibly convenient but in order to accurately read your test, it’s helpful to have pictures of positive Covid tests to use as a point of reference. They’re useful - and sometimes required - for many things, like international travel or even simply attending a large event, like a wedding. Even better, we now have access to at-home Covid tests so, if you’re well-stocked, we don’t even have to leave the house to take a test. Back at the start of the pandemic, tests were unreliable and nearly impossible to get, but now most of us can find a same-day appointment at drive-thru testing sites across our states. ![]() ![]() Covid testing has come a long way since 2020.
