What is the Dengue NS1 Test?
Dengue NS1 antigen test detects the dengue virus directly in blood during the first 5 days of fever. It's the earliest dengue marker — positive even before antibodies develop. In Bangalore during monsoon, this test is critically important for early dengue diagnosis when platelet monitoring can be started promptly.
Why Should You Take This Test?
Detects dengue before antibodies form. Critical for early diagnosis and monitoring in endemic regions.
