In Delhi, dengue tests are commonly conducted to diagnose the viral infection transmitted by Aedes mosquitoes. The most frequently used tests include the NS1 antigen test, which detects the virus early in the infection, and IgM/IgG antibody tests to determine the body's immune response. Dengue cases typically rise during the monsoon season, and timely testing is essential for early diagnosis and effective treatment. Testing facilities are available in government and private hospitals, as well as diagnostic centers across the city.
