Human immunodeficiency virus test evaluation, performance, and use. Proposals to make good tests better

Area of Science:

• Medical Diagnostics
• Infectious Diseases
• Public Health

Background:

• Human immunodeficiency virus (HIV) tests are vital for detecting asymptomatic infections and diagnosing AIDS-related conditions.
• Concerns regarding test accuracy contribute to ongoing controversies surrounding the use of HIV assays.
• A comprehensive review of the scientific basis for HIV test evaluation, performance, and application is warranted.

Purpose of the Study:

• To review the scientific basis for the evaluation, performance, and use of common HIV assays.
• To identify areas for improvement in HIV testing procedures and laboratory standards.
• To enhance the clinical utility of HIV tests through appropriate sequencing and interpretation.

Main Methods:

• Review of scientific literature on HIV assay evaluation and performance.
• Analysis of factors influencing current HIV test accuracy and utility.
• Examination of methodologies for minimizing bias in test evaluations.

Main Results:

• Current HIV test performance can be enhanced through standardization and mandatory proficiency testing.
• Test utility can be improved by appropriate test sequencing and result interpretation based on clinical context and population characteristics.
• Existing evaluation methods for HIV tests are affected by spectrum bias, referral bias, and inadequate reference standard confirmation.

Conclusions:

• Standardization, proficiency testing, and licensure of laboratories are crucial for improving HIV test performance.
• Appropriate test sequencing and interpretation in clinical and population contexts are essential for enhancing test utility.
• Revising HIV test evaluation methodologies to minimize bias and ensure adequate confirmation is necessary for reliable diagnostic outcomes.
