Hepatitis A Virus ( HAV ) RNA - Qualitative PCR WB-EDTA
Also Known As
Test Parameters Included
- Hepatitis A Virus RNA Detection (Qualitative) - presence/absence of viral genetic material
- Pathologist Virology Remark - correlated with acute infection status and clinical context
Department
Methodology
Sample Required
Preparation
* No Specific Time of Day: Blood can be drawn at any time of day.
* Medications: Inform your doctor about any medications you are taking, though they are unlikely to interfere with this PCR test. Do not stop any prescribed medication without consulting your doctor.
* Sample Type: WB-EDTA (3ML). It is critical to use the correct EDTA (lavender/purple top) tube. The blood sample must be processed rapidly (centrifuged) to separate the plasma, and the plasma should be promptly frozen (usually at -70° or colder) if it cannot be transported and tested immediately. This is crucial as viral RNA can degrade if not properly preserved.

Frequently Asked Questions
What does this test detect?
It detects the genetic material (RNA) of Hepatitis A virus in whole blood, indicating an active infection.
When is this test ordered?
It is used for early diagnosis of acute Hepatitis A, especially before antibodies (IgM) become detectable, or in immunocompromised patients.
Is fasting required for this test?
No, fasting is not required for HAV RNA PCR. Sample can be collected at any time.
How is the sample collected?
Blood is drawn from a vein into an EDTA tube (3 mL volume) for molecular testing.
What does a positive result mean?
A positive result confirms the presence of Hepatitis A virus RNA, indicating an active infection requiring clinical management.
How long does it take to get results?
Results are typically available within 24–48 hours after sample receipt at the laboratory.
