Dengue IgM Antibody (EIA) (IO0053)

Description

Dengue IgM Antibody (EIA) is a serological blood test used to detect IgM antibodies against Dengue virus in serum, helping in the diagnosis of recent or acute dengue infection. This test is commonly performed using Enzyme Immunoassay (EIA) / ELISA / MAC-ELISA methodology and is especially useful in patients with fever, body pain, headache, retro-orbital pain, rash, thrombocytopenia, or suspected mosquito-borne viral infection. Dengue IgM antibodies generally become detectable 4–5 days after symptom onset and may remain detectable for up to about 3 months. During the first 0–7 days of illness, this test is often recommended together with Dengue NS1 antigen or NAAT/PCR, because early IgM can still be negative. A positive result suggests presumptive recent dengue infection, but interpretation should consider cross-reactivity with other flaviviruses such as Zika, West Nile, or Yellow Fever.

Pre-Test Instructions:

No fasting required
Collect serum sample in plain red-top tube or SST (gel barrier tube)
Serum is the preferred specimen for dengue serology.
IgM usually becomes detectable 4–5 days after symptom onset, so very early samples may be false negative.
During the first 0–7 days of illness, CDC recommends combining Dengue IgM with NS1 antigen or NAAT/PCR for better diagnosis.
If the early sample is negative and dengue is still suspected, a repeat (convalescent) sample after >7 days may be required.
Positive IgM in a single sample suggests presumptive recent dengue infection, not always definitive confirmation.
Results may show cross-reactivity with other flaviviruses (e.g., Zika, West Nile, Yellow Fever), so clinical correlation is important.
Avoid hemolyzed, lipemic, contaminated, or insufficient samples
Always interpret with clinical symptoms, CBC/platelets, Dengue NS1, and physician advice
