Introduction to HEV IgG/IgM Testing

The HEV IgG/IgM test is a serological assay employed to detect the presence of antibodies to the Hepatitis E virus (HEV) in human blood. This test differentiates between IgG and IgM antibodies, indicating past or recent HEV infection, respectively.

Understanding Hepatitis E Virus (HEV)

Hepatitis E is a viral hepatitis caused by infection with HEV, a small, non-enveloped, positive-sense, single-stranded RNA virus. Predominantly transmitted via the fecal-oral route, HEV is a leading cause of acute viral hepatitis in many developing countries.

HEV IgG/IgM Test: Purpose and Functionality

The HEV IgG/IgM test serves to determine the immune status of individuals by detecting antibodies generated in response to HEV infection. IgM antibodies are indicative of recent infection, while IgG antibodies suggest past infection or immunity. This differentiation guides clinical decision-making and public health interventions.

Clinical Applications of HEV IgG/IgM Testing

HEV IgG/IgM testing is invaluable in:

• Diagnosing acute HEV infection.
• Determining immune status in endemic regions.
• Screening blood donors to prevent transfusion-transmitted HEV infection.

Parameters and Interpretation of HEV IgG/IgM Results

The results of the HEV IgG/IgM test are typically presented as follows:

• IgM Positive/IgG Negative: Indicates a recent HEV infection.
• IgM Negative/IgG Positive: Suggests past infection or immunity.
• IgM Positive/IgG Positive: May indicate a recent infection with the presence of lingering IgG antibodies.
• IgM Negative/IgG Negative: No evidence of past or recent HEV infection.

Numerical values of antibody titers can further stratify the test results, where higher optical density (OD) values suggest a stronger immune response.
