Introduction

The HAV IgG/IgM test cassette is a diagnostic tool used to detect the presence of Immunoglobulin G (IgG) and Immunoglobulin M (IgM) antibodies against the Hepatitis A Virus (HAV) in human serum, plasma, or whole blood. This test is crucial for diagnosing and monitoring Hepatitis A infections, which are caused by the Hepatitis A virus. The cassette-based testing method provides rapid results, which facilitate timely clinical decisions.

Functionality of the HAV IgG/IgM Test Cassette

The HAV IgG/IgM test cassette is designed to be a qualitative test, identifying the presence or absence of specific antibodies. The primary components are:

• IgM Antibody Detection: Indicates a recent or acute HAV infection. IgM antibodies typically become detectable 5-10 days before symptom onset and persist for about 6 months.
• IgG Antibody Detection: Reflects past exposure and potential immunity to the virus. IgG antibodies appear after IgM and can be detectable for a lifetime.

A test strip embedded in the cassette shows two lines—control and test lines. The presence of both lines denotes a positive result for the specific antibody type being tested.

Clinical Significance

The detection of HAV IgG and IgM offers significant clinical insights:

• Acute Infection Diagnosis: Positive IgM results confirm an acute or recent infection, crucial for immediate treatment and isolation measures to prevent outbreaks.
• Immunity Assessment: Positive IgG results suggest prior exposure or successful vaccination, indicating immunity.

The HAV IgG/IgM test cassette is essential in outbreaks and screening high-risk groups with a sensitivity and specificity often exceeding 95% in clinical settings.
