That's why you could test negative even if you have coronavirus
A shocking number of results are inaccurate, according to a recent study.
The race to increase Covid-19 tests across the country finally begins to pay. With more test facilities at the national level, it is now much easier for anyone who is afraid they are sick to become ashen and get answers. Now, the question is: what is the accuracy of coronavirus test results? According to a recent study, a lotTests return false negatives, usually becauseThey are administered too soon or too late in patient's disease.
The study published inthe Annals of internal medicine, found this64% of COVID-19 tests given four days after patients showed poorly determined symptoms of patients withnothave coronavirus. Perhaps even more shocking is that patients tested one day after their infection returned a false negative result nearly 100% of the time.
Although the results like this can suggest timing, that's all, the study still findsinaccuracies with testing the line. Patients tested eight days after the infection, there was always 20% chance to show a false positive result. And those who have been tested at the exact day, their symptoms have begun to receive 38% chance to receive an erroneous test result.
Emily Landon, MD, aEpidemiologist and Infectious Disease Specialist At the University of Chicago Medicine, told the NPR that the Covid-19 contagion takes at least three to five days after exposure to the positive test. However, the outlet warned in the same way as "A negative test should not be seen as your ticket stop being careful. "
"A negative test, if a person has symptoms or not, does not guarantee that they are not infected with the virus"Lauren Kucirka, MD, an obstetrics and a gynecology reside at Johns Hopkins Medicine, saidThe daily mail. "How do we respond and interpret, anegative test is very important because we endanger other people when we assume that the test is perfect. However, those infected with the virus are still able to potentially propagate the virus. "

The study highlights a long-standing problem in the medical community ofIdentify potential coronavirus carriers as soon as possible. Without precise precise detection, it can be much harder to isolate anyone who is contagious and prevents them from spreading the disease.
The authors of the study argue that these findings should change the way doctors treat patients with CVIV-19 symptoms. By sensitizing to test inaccuracies, doctors can wait and test again to be sure of their diagnosis. The authors suggest that "clinicians should consider waiting [one to three] days after the appearance of the symptoms to minimize the likelihood of a false negative result".
