Description
Dengue IgG /IgM/ IgA/NS1
Sample Type:Serum
Tests Included:
Detection of Dengue virus-specific antibodies (IgG, IgM, IgA) and NS1 antigen.
Sample Required:
Blood sample.
Test Time:
Results are typically available within a few days.
What is the test?
The Dengue serology test detects antibodies (IgG, IgM, IgA) produced by the body in response to Dengue virus infection and NS1 antigen, a protein produced by the virus.
Test Procedure:
A blood sample is collected and analyzed to detect specific Dengue antibodies or antigens.
When to take the test:
During the acute phase of Dengue infection or when there’s suspicion of Dengue fever.
Who should take the test:
Individuals presenting symptoms consistent with Dengue fever, especially in areas where Dengue is prevalent.
Precautions for exceptional cases (pregnancy, etc.):
Specific considerations might be necessary for pregnant individuals or those with compromised immune systems.
Frequently Asked Questions (FAQs) for Dengue Serology Test:
Q1: What do IgG, IgM, IgA, and NS1 indicate in Dengue infection?
A: IgM and NS1 are often detectable during the acute phase, while IgG appears later and indicates past exposure or immunity.
Q2: Can Dengue antibodies from a previous infection cause false-positive results?
A: Yes, previous exposure might result in positive IgG results, which can persist for a long time.
Q3: Can the test distinguish between different Dengue virus serotypes?
A: Some tests can differentiate between different serotypes, which is important in managing severe Dengue cases.
Q4: Is there a specific treatment for Dengue fever based on these tests?
A: Treatment is usually supportive as there’s no specific antiviral therapy, and early detection helps in managing complications.
Q5: Can Dengue serology tests detect the presence of the virus in mosquitoes?
A: No, these tests are used for detecting Dengue infection in humans and not in mosquitoes.
