Serum, NA, Fasting or Non Fasting: As suggested by doctor
Sample Required:
The Dengue IgG Antibody test typically requires a blood sample. This blood sample is usually obtained through a standard blood draw from a vein in your arm.
Test Time:
The results of the Dengue IgG Antibody test are usually available within a few hours to a few days, depending on the specific laboratory’s processing time.
Test Normal Range:
The Dengue IgG Antibody test does not measure results in a typical reference range. Instead, it detects the presence or absence of Dengue virus-specific IgG antibodies in the blood.
What is the Test?
The Dengue IgG Antibody test is a diagnostic test used to detect the presence of specific IgG antibodies against the Dengue virus in the blood. These antibodies are produced by the immune system in response to a previous Dengue virus infection.
Test Procedure:
A healthcare provider or phlebotomist cleans the injection site (usually the arm) with an antiseptic. A needle is used to draw a blood sample from a vein. The blood sample is processed in a laboratory to detect Dengue virus-specific IgG antibodies.
When to Take the Test:
The Dengue IgG Antibody test is typically performed several days to weeks after the onset of Dengue fever symptoms or when there is suspicion of a past Dengue virus infection.
Who Should Take This Test:
Individuals who have previously experienced Dengue fever or suspected they have been infected with the Dengue virus. Those seeking confirmation of a past Dengue virus infection for medical or travel-related purposes.
Precautions for Exceptional Cases (Pregnancy, etc.):
Pregnant individuals or those with specific medical conditions should consult their healthcare provider before taking the Dengue IgG Antibody test. Clinical context may be important for interpretation. In the case of pregnancy, additional precautions may be advised.
FAQs (Frequently Asked Questions):
Q1: What does a positive Dengue IgG Antibody test mean?
A: A positive result indicates that specific IgG antibodies against the Dengue virus are present in your blood, suggesting a past infection or exposure to the virus.
Q2: Can this test determine if I currently have Dengue fever?
A: No, the Dengue IgG Antibody test is not used to diagnose active Dengue infections. It is used to confirm past exposure or infection.
Q3: How long do Dengue IgG antibodies persist in the blood after an infection?
A: Dengue IgG antibodies can persist for months to years after an infection, providing long-term immunity against the virus.
Q4: Is a positive Dengue IgG Antibody test protective against future Dengue infections?
A: While previous infection may provide some immunity against the same Dengue virus serotype, it does not provide immunity against other serotypes.
Q5: Can I travel if I test positive for Dengue IgG antibodies?
A: Travel decisions should be made in consultation with a healthcare provider, taking into account your health and the risk of future Dengue infections in the destination.
