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.
