This test helps find specific antibodies made by your body when you get infected with the dengue virus. It detects IgM antibodies, which show that you have recently caught dengue fever, a virus spread by mosquitoes. Testing these antibodies helps doctors confirm if symptoms like high fever, headache, or skin rash are due to dengue. Early diagnosis is important to monitor your health closely and take proper care. The test is done on a blood sample and does not require fasting, making it simple and quick.

Why is it Important

Early detection: Identifying dengue infection early helps in timely medical care to avoid complications.
Confirmation of dengue fever: Symptoms of dengue overlap with other infections; this test confirms if dengue virus is the cause.
Guides treatment: Knowing if you have dengue lets healthcare providers monitor platelet counts and manage symptoms appropriately.
Prevents spread: Confirmed cases allow public health measures to reduce mosquito bites and help control outbreaks.
Monitors recovery: IgM antibody levels help tell if infection is recent or past, guiding follow-up tests as needed.

When Should I Get This Test?

You should consider this test if you experience:

Sudden high fever with severe headache or eye pain
Muscle and joint pain often called "breakbone fever"
Fatigue or weakness after a mosquito bite
Skin rash appearing a few days after fever
Bleeding signs like nose or gum bleeding or easy bruising

Interpretation of Test Results
