HAV IgG/IgM
Product information
Intended use
The HAV IgG/IgM Rapid Test is a lateral flow chromatographic immunoassay for the qualitative detection and differentiation of antibodies (IgG and IgM) to hepatitis A virus (HAV) in human serum, plasma.
Principle
The HAV IgG/IgM Rapid Test utilizes a lateral flow chromatographic immunoassay with a test strip featuring HAV antigens and colloidal gold. The G line, coated with mouse anti-human IgG, indicates HAV IgG positivity, while the M line, coated with mouse anti-human IgM, indicates HAV IgM positivity. Absence of G or M lines suggests a negative result. The internal control line (C line) ensures test validity; an invalid result requires retesting with another device.
Testing Procedure
Importance to know
Warnings and Precautions
-
Please read the instruction carefully before performing the test.
-
Do not use the test after the expiration date.
-
Immediately carry out the test after removing the test device from the pouch.
-
Do not mix or interchange the specimen sample.
Limitation
-
Strictly follow the Assay Procedure and Interpretation of Assay Result sections to avoid inaccurate outcomes.
-
The HAV IgG/IgM Rapid Test qualitatively detects antibodies to HAV in serum, plasma.
-
Test line intensity doesn't correlate linearly with antibody titer; negative result doesn't rule out exposure or infection.
-
A negative result may occur if antibody levels are below detectable limits or absent during the disease stage.
-
Negative result doesn't exclude acute infection; early samples may have undetectable IgM levels.
-
Consider alternative testing if symptoms persist, even with a negative result, and high heterophile antibodies may affect accuracy.
-
Presence of anti-Hepatitis A IgG may result from past infections or vaccination.
