Understanding Your Results
Detected
Dengue virus RNA is present, indicating active dengue infection. Clinical correlation is recommended.
Not Detected
Dengue virus RNA is not found in the sample. However, if symptoms persist, repeat testing or other dengue tests may be advised due to possible low viral load or early/late infection.
Consult a doctor immediately if you have symptoms such as high fever, severe headache, or signs of severe dengue like bleeding, abdominal pain, or lethargy, regardless of test results.
Limitations
- ⚠This test is qualitative and does not quantify viral load
- ⚠May not distinguish between dengue serotypes (DENV-1, DENV-2, DENV-3, DENV-4)
- ⚠False negatives possible if tested too early or late in infection
- ⚠Cannot be used alone for monitoring treatment response
Risks & Considerations
- ●Slight pain or bruising at the blood draw site
- ●Rare risk of infection or dizziness
- ●For CSF collection, potential headache or back pain (under medical supervision)
Interfering Factors
- ●Hemolyzed or lipemic samples may affect accuracy
- ●Improper sample storage or transport
- ●Low viral load below detection limit
- ●Contamination during sample collection
