Dengue IgG and IgM Test

Dengue igg or igm test is done for diagnosis of dengue infection. It should ideally be done after 2 weeks of development of symptoms in patient. Most patients will develop IgG antibodies against dengue by 2-3 weeks post primary infection. However, when the patient has dengue for the second time (secondary dengue) the IgG antibodies rise within 2 days of development of symptoms
Patients, post first infection with a different serotype of dengue virus can develop severe form of disease with the following symptoms: abdominal pain, persistent vomiting, bleeding from nose, gums, blood in stool and restlessness.

Dengue igg or igm test  detects presence of dengue virus in the blood

The blood sample is taken from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a  little sting when the needle goes in or out. This usually takes less than five minutes.

Negative

A positive IgG result is consistent with exposure to dengue virus. Time of collection of sample is important for interpretation of results. Patients with secondary dengue (at risk of severe dengue) develop IgG antibodies early on in the disease. It is important to remember that IgG antibodies remain positive for years together and should not be interpreted in isolation.
A negative IgG test can result if sample is collected early on in the primary infection. A timely collected sample with negative result means lack of exposure to dengue virus in immunocompetent person
