Dengue test cost in Bangalore: NS1, IgM, IgG explained (2026)
Three different dengue tests are available, and which one you need depends on how many days into the illness you are. Here is what each costs at Bangalore labs.
$## Which dengue test do you need?
Dengue fever is caused by a virus transmitted by Aedes mosquitoes, and Bangalore sees outbreaks particularly during and after the monsoon season. Three main tests are used for diagnosis, and the right one depends on how long you have had symptoms.
NS1 Antigen Test: Detects the dengue virus antigen directly in the blood. Most accurate in the early phase of illness -- Day 1 to Day 5 of fever. After Day 5, the antigen becomes harder to detect as the immune response takes over.
IgM Antibody Test: Detects the immune response to dengue. IgM antibodies appear from around Day 4 to Day 5 of illness and remain detectable for several weeks. Used to confirm dengue in the second week of illness when NS1 may be negative.
IgG Antibody Test: Detects past dengue infection. IgG appears later than IgM and remains detectable for years. Useful for determining whether a current infection is a first or repeat dengue infection, which affects severity risk.
NS1 + IgM + IgG Combo Test (Dengue Trio): The most complete single test. Catches dengue at multiple stages. Most labs recommend this when the exact day of illness onset is uncertain.
Typical prices at Bangalore labs
NS1 Antigen alone: Rs. 300 to 700
Dengue IgM alone: Rs. 300 to 600
Dengue IgM + IgG: Rs. 400 to 800
Dengue NS1 + IgM + IgG Combo: Rs. 600 to 1,200
Dengue PCR (molecular test): Rs. 1,500 to 3,500. The most sensitive and specific test, but expensive. Rarely needed for routine dengue diagnosis -- typically reserved for atypical or complicated cases.
Preparation
No fasting required. The test is a simple blood draw and can be done at any time.
How long do results take?
Rapid antigen and antibody tests: 2 to 4 hours. Dengue PCR: 12 to 24 hours.
What to watch for alongside the test
A CBC is almost always ordered alongside a dengue test. Falling platelet counts are a hallmark of dengue, and the trend matters as much as the single reading. Low platelets with a positive dengue test usually requires medical monitoring.
Do not self-manage severe dengue symptoms. Hospitalisation may be needed for platelet monitoring and IV fluids if required.
