Dengue is a mosquito-borne viral infection caused by the dengue virus.

The Dengue Profile test combines detection of:

NS1 Antigen – appears early in infection (first 1–7 days).

IgM Antibodies – indicate recent or current infection.

IgG Antibodies – indicate past infection or secondary dengue.

This combined panel helps doctors identify whether the infection is acute, recent, or past, and distinguish between primary and secondary dengue.

Clinical uses include:

Early detection of dengue fever.

Differentiating between primary and secondary infections.

Supporting treatment decisions and monitoring disease progression.

The test is performed using a blood sample.

Analytes:

NS1 Antigen: Detects viral protein present in early infection.

IgM Antibodies: Appear within 4–5 days of infection, peak around 2 weeks.

IgG Antibodies: Appear later, persist for years, indicate past exposure or secondary infection.

Clinical Use:

Confirms dengue infection in suspected cases.

Helps determine stage of infection (early, recent, past).

Assists in differentiating dengue from other febrile illnesses.
