my test was negative
If you test negative for COVID-19, you probably were not infected at the time your sample was collected. However, that does not mean you will not get sick. The test result only means that you did not have COVID-19 at the time of testing. You may test negative if the sample was collected early in your infection and test positive later during your illness. You could also be exposed to COVID-19 after the test and get infected then. This means you could still spread the virus. If you develop symptoms later, you may need another test to determine if you are infected with the virus that causes COVID-19.
If you don’t have symptoms, you should get tested again only if your
medical provider and/or workplace tells you to. Take steps to protect
yourself and others.
If you have symptoms, you should keep monitoring symptoms and seek medical advice about staying home and if you need to get tested again.
