Dengue Fever NS1 Antigen near me in Kolkata

Dengue spreads via the bite of an infected Aedes aegypti mosquito, which carries the virus and commonly occurs in tropical and subtropical climates. Most infected individuals do not show symptoms. However, when symptoms occur, they commonly include high fever, body aches, headache, nausea, and skin rash. Usually, these symptoms improve in about 1-2 weeks, but people who develop a severe dengue infection may need hospitalization, as severe dengue can be fatal.

There is currently no specific treatment for dengue, so early diagnosis with the Dengue Fever NS1 Antigen test is important to avoid complications. If you have recently traveled to a dengue-prone area, get tested even if you have no symptoms. Expectant mothers should also get tested if an infection is suspected, as dengue can rarely spread from mother to baby. Taking proper rest, staying hydrated, and closely monitoring symptoms can help support recovery and prevent complications.

The Dengue Fever NS1 Antigen test detects the presence of the dengue virus at an early stage of infection by identifying the NS1 antigen in the blood. This test is most useful during the first 1–7 days after the onset of dengue symptoms, even before antibodies appear. A positive result confirms dengue infection, while a negative result may require follow-up antibody testing (IgM/IgG) if symptoms persist. This test also helps monitor disease progression and guide further medical evaluation.

Usually, no special preparation is needed for a dengue fever test. You can eat and drink as usual. However, inform your doctor about any medications or supplements you are taking, as they may affect your test results.

Dengue antigen test result ranges may vary across the laboratories depending on the methodology and laboratory guidelines. Do not self-medicate. Always consult your doctor to understand your test results correctly.
