DENGUE-NS1 ANTIGEN, IGG & IGM ANTIBODIES (RAPID METHOD) Test

The Dengue NS1 Antigen, IgG & IgM Antibodies – Rapid Method is a blood test that checks for three important markers of dengue virus infection: NS1 antigen, IgM antibodies, and IgG antibodies.

NS1 antigen can often be detected during the early stage of dengue infection, while IgM antibodies generally develop later and can indicate a recent infection. IgG antibodies usually indicate previous exposure to dengue and may also be detected during a secondary dengue infection.

Because these markers appear at different stages of illness, the combined rapid test can provide useful information when dengue is suspected. However, results should be interpreted along with the number of days of fever, symptoms, CBC, platelet count, and other clinical findings.

DENGUE-NS1 ANTIGEN, IGG & IGM ANTIBODIES (RAPID METHOD) Test is Recommended for Individuals:

• Individuals with fever and suspected dengue infection
• People experiencing headache, muscle pain, joint pain, or pain behind the eyes
• Patients with nausea, vomiting, or skin rash along with fever
• Individuals with unexplained low platelet counts
• People living in or travelling to areas where dengue is circulating
• Patients requiring evaluation for recent or previous dengue exposure
• Individuals advised by a healthcare provider based on symptoms and clinical findings

FAQs

1. What does the Dengue NS1, IgG & IgM rapid test detect?
It detects NS1 antigen and dengue-specific IgM and IgG antibodies. Together, these markers can help evaluate dengue infection at different stages.

2. What is the difference between Dengue NS1, IgM and IgG?
NS1 antigen is generally useful during the early phase of infection. IgM usually develops later and may indicate a recent infection, while IgG generally indicates previous exposure and can also be present during a secondary dengue infection.

3. Can a negative rapid dengue test rule out dengue?
Not always. Test accuracy can vary depending on the stage of infection. If symptoms strongly suggest dengue, a healthcare provider may recommend additional testing such as ELISA, PCR, or repeat antibody testing, along with CBC and platelet monitoring.
