Dengue Test

A positive result for the Dengue NS1 Antigen Test indicates the presence of NS1 antigen in the blood, suggesting an active dengue infection.

• It is important to note that the NS1 antigen test is most effective within the first few days of symptoms onset and may not detect the antigen in later stages of the infection.
• A negative result does not rule out dengue infection completely, and further testing or clinical evaluation may be necessary if dengue is strongly suspected.

The Dengue IgG Test involves collecting a blood sample from the individual, typically through a venipuncture.

• The collected blood sample is then tested for the presence of Dengue-specific IgG antibodies using laboratory techniques.
• The test results can indicate whether the person has previously been infected with the dengue virus and developed an immune response.

The Dengue IgM Test is a diagnostic test used to detect the presence of IgM antibodies in the blood of individuals suspected of having a current or recent dengue infection.

• IgM antibodies are produced by the immune system in response to a recent dengue infection and are usually detectable within a few days to weeks after the onset of symptoms.
• This test helps in the early diagnosis of dengue and can differentiate between a current or recent infection and a past infection.

There are several types of tests used for dengue diagnosis. The commonly employed tests include the NS1 antigen test, IgM antibody test, IgG antibody test, and PCR (Polymerase Chain Reaction) test. The NS1 antigen test detects the NS1 protein secreted by the dengue virus in the early stages of infection. IgM antibodies indicate recent infection, while IgG antibodies indicate past infection or previous exposure. PCR is a molecular technique that detects the genetic material of the virus. These tests are conducted using blood samples and are performed in medical laboratories or healthcare facilities. The choice of the test depends on factors such as the stage of infection, availability of resources, and the healthcare provider's recommendation. Each test plays a specific role in dengue diagnosis and provides valuable information for effective management of the disease.
