[ELISA for detecting antibodies against herpes simplex virus]

Area of Science:

• Immunology
• Virology
• Diagnostic Assay Development

Background:

• Herpes simplex virus (HSV) infections are common, necessitating reliable antibody detection methods.
• Accurate serological assays are crucial for diagnosing HSV infections, especially in immunocompromised individuals.
• Indirect ELISA is a widely used serological technique, but requires standardization for optimal performance.

Purpose of the Study:

• To normalize an indirect Enzyme-Linked Immunosorbent Assay (ELISA) for detecting herpes simplex virus (HSV) antibodies.
• To establish clear conditions and criteria for defining positive results in the standardized ELISA.
• To evaluate the performance of the normalized ELISA by comparing it with an established immunofluorescence technique.

Main Methods:

• Normalization of an indirect ELISA protocol for HSV antibody detection.
• Application of the normalized ELISA to serum samples from 89 immunocompromised patients and 76 blood bank donors.
• Comparative analysis of ELISA results with those obtained from the indirect immunofluorescence technique.

Main Results:

• The indirect ELISA test for HSV antibodies was successfully normalized.
• Specific conditions and criteria for positive test results were established.
• The results from the normalized ELISA showed agreement with the indirect immunofluorescence technique in the tested populations.

Conclusions:

• The normalized indirect ELISA provides a reliable method for detecting HSV antibodies.
• The established criteria ensure accurate interpretation of positive results.
• This standardized assay is suitable for use in clinical settings, including the evaluation of immunocompromised patients.
