SARS-CoV-2 PCR
The SARS-CoV-2 PCR test is a laboratory test used to detect the genetic material of the SARS-CoV-2 virus, which causes COVID-19. Clinicians typically order this test when a patient exhibits symptoms of COVID-19, such as fever, cough, or difficulty breathing, or when they have been in close contact with someone who tested positive. It is also used for screening purposes in various settings, such as before surgeries or travel. The SARS-CoV-2 PCR test is considered the gold standard for diagnosing an active infection, as it provides highly accurate results in identifying the presence of the virus.

Clinical Information
Clinical Significance
Abnormal results in the SARS-CoV-2 PCR test, such as a positive finding, indicate the presence of the virus, which may require isolation and further medical evaluation. Conversely, a negative result suggests that the virus was not detected at the time of testing. However, it is crucial to remember that only a healthcare provider can interpret these results in the context of symptoms and exposure history, guiding appropriate follow-up actions.
Reference Ranges
The reference ranges for the SARS-CoV-2 PCR test are interpreted based on the presence or absence of the virus's genetic material in the sample. A positive result indicates an active infection, while a negative result suggests the absence of the virus at the time of testing. These results may vary based on individual circumstances and the testing methods used by different laboratories.
Sample Preparation
Before your SARS-CoV-2 PCR test, no special preparation is necessary. You do not need to fast or stop any medications unless your healthcare provider advises otherwise. It is important to inform your healthcare provider about any medications you are taking or any recent symptoms you may have experienced.
