COVID-19 PCR Test
A COVID-19 PCR (Polymerase Chain Reaction) test is a highly accurate molecular test used to detect an active infection with SARS-CoV-2, the virus that causes COVID-19. Unlike rapid antigen tests, the PCR test is considered the gold standard for diagnosis because of its high sensitivity and specificity.

How the PCR Test Works
- Sample Collection: A trained healthcare professional collects a sample, typically using a nasopharyngeal swab (deep nasal swab). This swab collects respiratory secretions that may contain the virus. In some cases, a saliva sample may be used instead.
- Lab Analysis: The sample is sent to a certified laboratory for analysis. The lab extracts genetic material from the sample and uses a process called PCR to amplify a specific segment of the virus's RNA. If the virus's genetic material is present, even in very small amounts, the PCR process will make millions of copies, making it detectable.
- Result: The presence of the amplified viral RNA confirms an active COVID-19 infection. The process is precise, reliable, and can detect the virus very early in the course of an infection.
Why Choose a PCR Test?
- High Accuracy: PCR tests are the most accurate way to detect an active COVID-19 infection. The test's sensitivity means it's excellent at finding the virus even in small quantities, and its specificity ensures it doesn't confuse the SARS-CoV-2 virus with other viruses.
- Early Detection: The test can detect the virus early in the infection cycle, often before symptoms appear, which is crucial for preventing further spread.
- Required for Travel & Medical Procedures: Many countries and medical facilities require a negative PCR test for travel, surgical procedures, or other specific reasons.
What to Expect
- Preparation: No special preparation is needed for a COVID-19 PCR test. You should not use nasal sprays or nasal rinses for at least two hours before your test, as they can affect the sample.
- The Process: The nasal swab may cause a brief, ticklish sensation or minor discomfort, but the procedure is very quick.
- Results: Your results are typically available within 24-72 hours. We will notify you as soon as they are ready.
