Dengue Qualitative RNA PCR, EDTA PLASMA
Also Known As
Test Parameters Included

- Pathologist Molecular Virology Remark - reported as Detected / Not Detected with serotype indication if applicable
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: EDTA Plasma (minimum volume typically 2-4 mL, check lab specific requirements). It is crucial 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^\circ C or colder) if it cannot be transported and tested immediately, as viral RNA is prone to degradation.

Frequently Asked Questions
What does Dengue Qualitative RNA PCR detect?
It detects the genetic material (RNA) of the Dengue virus, identifying active infection during the early phase when the virus is circulating in the blood.
When is this test most useful?
It is most valuable during the first 1-7 days of fever, before antibodies develop. It is particularly useful when NS1 antigen is negative or serology is still seronegative in early infection.
What sample is required for this test?
Whole blood collected in EDTA tube (3 mL) or separated EDTA plasma. The sample must be transported and stored at 2-8°C and processed promptly.
How is the result interpreted?
A 'Detected' result confirms active Dengue virus infection and may include serotype identification (DENV-1 through DENV-4). A 'Not Detected' result does not completely rule out dengue if testing is done too early or late in the illness.
Is fasting required for this test?
No, fasting is not required. The sample is collected in an EDTA tube and can be drawn at any time of day regardless of food intake.
How long does it take to get results?
Results are typically available within 24 hours. Verified PDF reports can be accessed via www.drpatholab.in or WhatsApp/Email.
