Centers for Disease Control perspective on quality assurance for human immunodeficiency virus type 1 antibody...

Area of Science:

• Clinical diagnostics
• Public health surveillance
• Virology

Background:

• High-quality human immunodeficiency virus type 1 (HIV-1) antibody testing is vital for controlling epidemic HIV-1 infection.
• The Centers for Disease Control established the Model Performance Evaluation Program (MPEP) in 1986.
• MPEP aims to assess and enhance the analytic quality of HIV-1 antibody testing and gather data on testing practices.

Purpose of the Study:

• To evaluate the quality of HIV-1 antibody testing practices.
• To identify barriers affecting the total testing process.
• To assess the impact of laboratory practices on overall testing quality.

Main Methods:

• The Model Performance Evaluation Program (MPEP) was utilized.
• A questionnaire was administered to 1050 participating laboratories in September 1988.
• Data on laboratory practices, including Western blot interpretation, were collected.

Main Results:

• 1405 laboratories, including hospitals, blood banks, and independent labs, participate in MPEP.
• Responses from 1050 laboratories indicate variability in HIV-1 antibody testing practices.
• Inconsistent practices were observed at multiple stages, including Western blot pattern interpretation.

Conclusions:

• Standardization of laboratory practices is essential for improving HIV-1 antibody testing quality.
• Addressing variability in testing processes can mitigate barriers to quality.
• The MPEP provides valuable insights into laboratory performance and identifies areas for improvement.
