Blood tests that help confirm dengue infection.
General health information, not a diagnosis. In an emergency, call 102. Always consult a qualified health professional.
The Dengue NS1 / IgM test is a blood test that helps confirm a dengue infection. It measures the dengue NS1 antigen (early) or IgM/IgG antibodies (later) in the blood. This test is used to confirm dengue in someone with fever, especially during the monsoon season. No special preparation is needed. A small blood sample is taken from a vein. The test results may indicate a positive NS1 or IgM, supporting the dengue infection. Timing of the results is important, as a doctor interprets them with the patient's symptoms and blood counts.
