Covid standard range not detected. If your COVID-19 test was negative, this means that the test did not detect the presence of COVID-19 in your nasal secretions. This result would suggest that you are not currently infected with COVID-19. The standard range labeled 'negative' means no virus was detected. "Standard Range: Not Detected" means the normal ("standard") result is not to have COVID detected in the sample. For COVID-19, a negative or not detected test result for a sample collected while a person has symptoms usually means that COVID-19 did not cause your recent illness. A negative or not detected test result means that the virus that causes COVID-19 was not found in your sample. • If you have no symptoms of COVID-19, receive a positive antigen test result AND receive a negative PCR test result within 48 hours of each other, then you would not be considered to be currently infected with COVID-19. s why a test can be indeterminate. When a Covid-19 test shows 'detected abnormal,' it indicates that the test detected the presence of the virus, but the results are not within the expected range. Positive results require following public health guidelines such as isolation to prevent spread. The most common reason is when a specimen generates an error on all COVID testing instruments attempted indicating there is an interfering substance of unknown type in the specimen or the test result is only positiv. cxwcf ztkt omkmy tcovcn tvd iwjzjrh tkpd hzjia moyeeko mgfpiz
