Description
Covid-19 PCR SARS-CoV-2 RNA
Sample Type:Contact Lab
Sample Required:
Nasal or throat swab
Test Time:
Results are typically available within a few days.
What is the test?
The COVID-19 PCR test detects the genetic material (RNA) of the SARS-CoV-2 virus, confirming the presence of an active infection.
Test Procedure:
A sample is collected from the nose or throat using a swab. The genetic material is then extracted, and a Polymerase Chain Reaction (PCR) is performed to detect viral RNA.
When to take the test:
When there’s suspicion of a current COVID-19 infection, particularly in individuals exhibiting symptoms or with potential exposure to the virus.
Who should take the test:
Individuals showing symptoms of COVID-19, those with known exposure to the virus, or those requiring confirmation of infection status might undergo this test.
Precautions for exceptional cases (pregnancy, etc.):
Pregnant individuals might undergo this test if there’s a concern about potential COVID-19 infection during pregnancy.
Frequently Asked Questions (FAQs) for COVID-19 PCR SARS-CoV-2 RNA Test:
Q1: How accurate is the PCR test in detecting COVID-19?
A: PCR tests are highly accurate in detecting viral RNA and are considered the gold standard for diagnosing current infections.
Q2: When is the best time to take the PCR test after exposure?
A: It’s recommended to wait a few days (usually 5-7 days) after exposure to allow for the virus to replicate to detectable levels.
Q3: Can a negative PCR test rule out COVID-19 infection?
A: A negative result doesn’t entirely rule out infection, especially if taken too early or if the sample collection wasn’t optimal.
Q4: How long after infection can viral RNA be detected?
A: Viral RNA can be detected in the early stages of infection, usually within the first week after symptoms start, and can persist for some time.
Q5: Can the PCR test distinguish between different strains of the virus?
A: Specific PCR tests can identify different variants of the virus by targeting specific genetic sequences, sbut it’s not standard in routine tests.
*Please note that specific testing protocols and guidelines may vary based on the latest recommendations from health authorities and regulatory agencies. It is essential to consult healthcare professionals and follow local testing guidelines for accurate and appropriate testing.
