SARS-CoV-2 Genomic Sequence Detection by Qualitative Nucleic Acid Amplification Probe

This test measures specific substances in your body, giving your healthcare provider a clear picture of how well certain organs and systems are working. The results help identify potential health concerns early, support an accurate diagnosis, and guide decisions about any treatment or follow-up care you may need.

The test looks for specific genetic sequences from the SARS-CoV-2 virus, which causes COVID-19. It uses a probe-based nucleic acid amplification technique to identify these sequences in a sample of your respiratory tract (e.g., nasal or throat swab).

During the test, a small sample is collected from your body and sent to a laboratory, where specialized equipment analyzes it. The lab measures the levels of particular markers in your sample, and your provider compares those values against standard reference ranges to understand what they mean for your overall health.

The test amplifies and detects tiny amounts of viral genetic material. If the virus is present, the probe binds to its genetic sequence, triggering a detectable signal. This confirms whether you are currently infected with COVID-19.

Your doctor may recommend this test if you have symptoms that point to a possible health problem, if you live with a chronic condition that needs regular monitoring, or as part of a routine checkup. It can also show whether a current treatment is working or help screen for conditions before any symptoms develop.

This test is typically ordered if you have symptoms of COVID-19 (such as fever, cough, or shortness of breath), have been exposed to someone with the virus, or if you are required for screening in certain settings (e.g., travel, healthcare visits).

Before the test, your healthcare provider will give you specific instructions to follow. Depending on the type of test, you may need to avoid eating or drinking for a set number of hours, temporarily pause certain medications or supplements, or skip strenuous exercise. Always mention every medication you take, and ask questions if any instruction is unclear.

No special preparation is needed. You will provide a sample via a nasal or throat swab, similar to a cold test. Wear a mask if possible to avoid spreading germs during the procedure.
