Are there any limitations to COVID-19 PCR tests?

For specific information about the limitations of the IBX Test, please refer to the patient fact sheet. You may also refer to the questions above, “What does it mean if I have a positive test result?” and “What does it mean if I have a negative test result?” questions above.

A PCR test may not detect the virus in early stages of infection. In addition, a PCR test may not detect the virus if there was a problem with your sample, such as when the sample is not collected as directed. There is also the possibility of a false negative (a negative result that is incorrect) even if you’ve had recent exposure to the virus along with symptoms consistent with COVID-19.
