Dengue Profile ELISA Method

DENGUE PROFILE ELISA METHOD Test

The Dengue Profile – ELISA Method is a blood test used to evaluate suspected dengue virus infection by detecting dengue-related markers such as NS1 antigen and/or IgM and IgG antibodies, depending on the laboratory's specific profile.

The combination of these markers can provide useful information about dengue infection at different stages. NS1 antigen is generally useful during the early phase of illness, while IgM antibodies become detectable later and may indicate a recent infection. IgG antibodies can provide evidence of previous exposure and may also be seen during a secondary dengue infection.

ELISA-based testing can therefore help healthcare providers assess dengue when interpreted alongside the day of illness, symptoms, CBC, platelet count, and other clinical findings.

DENGUE PROFILE ELISA METHOD: Test is Recommended for Individuals:

• Individuals with fever and suspected dengue infection
• People experiencing severe headache, body aches, or pain behind the eyes
• Patients with nausea, vomiting, or skin rash accompanied by fever
• Individuals with unexplained low platelet counts
• People living in or travelling to areas where dengue is circulating
• Patients requiring evaluation of dengue infection at different stages
• Individuals advised by a healthcare provider based on symptoms and clinical findings

FAQs

1. What does a Dengue Profile ELISA test detect?
Depending on the laboratory's profile, the test may detect Dengue NS1 antigen, IgM antibodies, and IgG antibodies. These markers help evaluate dengue infection according to the stage of illness.

2. What is the difference between NS1, IgM, and IgG in dengue testing?
NS1 antigen is generally useful during the early stage of infection. IgM antibodies usually become detectable later and may indicate a recent infection, while IgG antibodies generally indicate previous exposure and may also be present during a secondary infection.

3. Is the Dengue Profile ELISA test enough to confirm dengue?
The results should be interpreted along with the timing of symptoms, clinical findings, CBC and platelet count, and other relevant tests. The appropriate dengue test can vary depending on how many days the person has had symptoms.
