Test Parameters Included

  • NS1 Antigen: A non-structural protein of the dengue virus, NS1 is detectable in the blood during the acute phase of infection, often within the first day of fever onset and typically for up to 5-7 days. Its early presence helps in rapid diagnosis during the initial stages of illness.
  • IgM Antibodies: These antibodies are usually detectable from about 3-5 days after the onset of fever and typically persist for several weeks to months. Their presence indicates a recent or primary dengue infection.
  • IgG Antibodies: These antibodies appear later than IgM, typically around 7-10 days after fever onset, and can persist for years, providing long-term immunity. Their presence, especially without IgM or NS1, might indicate a past infection, while a rise in IgG alongside IgM suggests a secondary (recurrent) dengue infection, which carries a higher risk of severe dengue.

Methodology

ELISA Quantitative : This test employs the Enzyme-Linked Immunosorbent Assay (ELISA) technique, a highly sensitive and specific method for the quantitative detection of specific viral antigens and antibodies in blood samples. For dengue diagnosis, ELISA is utilized to simultaneously measure NS1 antigen (an early marker of infection) and Dengue-specific IgM and IgG antibodies, providing a comprehensive view of the patient's infection status and stage.

Sample Required

SERUM (1ML)

Preparation

* No Fasting Required: Fasting is generally not required for this blood test. You can eat and drink normally before the sample collection. * Medication Disclosure: Inform your healthcare provider about any medications, supplements, or recent treatments you are undergoing. However, these generally do not interfere with dengue serology or antigen tests. Do NOT stop any prescribed medication without consulting your doctor. * Recent Travel History & Symptom Onset: Provide your doctor with information on recent travel to dengue-endemic areas and the exact date of symptom onset, as this is crucial for interpreting NS1 and antibody results in relation to the infection stage. * Hydration: Staying well-hydrated is always recommended before any blood draw to ensure easier vein access.

Frequently Asked Questions

Is fasting required for Dengue profile?

No, fasting is not required. Sample can be collected anytime regardless of meal intake.

What is the best time to test for NS1 antigen?

NS1 is most detectable during the first 1-7 days of fever onset, representing the acute viremic phase.

How are IgG and IgM results interpreted together?

IgM indicates recent/acute infection, while IgG suggests past exposure or recovery. Both positive may indicate recent infection; only IgG positive suggests prior immunity.

Can dengue be detected if symptoms started 5 days ago?

Yes, NS1 may still be positive up to day 7, and IgM typically becomes detectable from day 3-5 onwards.
