Comparisons of New HIV Rapid Test Kit Performance

Area of Science:

• Infectious Disease Diagnostics
• Public Health Surveillance
• Biomedical Technology

Background:

• Rapid point-of-care (POC) testing for Human Immunodeficiency Virus (HIV) has significantly improved patient follow-up rates.
• The trend in diagnostic development is shifting towards multiplex testing, enabling simultaneous detection of multiple diseases.

Purpose of the Study:

• To evaluate the diagnostic performance, specifically sensitivity and specificity, of HIV tests when incorporated into multi-disease test kits.
• To assess the efficacy of oral fluid-based HIV tests within multiplex diagnostic platforms.

Main Methods:

• A cohort of 1029 participants was enrolled between 2011 and 2014.
• Sensitivity and specificity of various HIV test kits, including those designed for multiplex use, were calculated.
• Performance data from oral fluid HIV tests within these kits were specifically analyzed.

Main Results:

• HIV test kit sensitivities in multiplex kits ranged from 91.1% to 100%.
• HIV test kit specificities in multiplex kits ranged from 99.5% to 100%.
• HIV tests utilizing oral fluid demonstrated comparable performance to blood-based tests within the multiplex kits.

Conclusions:

• HIV testing integrated into multi-disease POC kits maintains high diagnostic accuracy.
• Multiplex testing platforms, including those using oral fluid, are viable for efficient HIV screening.
• These findings support the continued development and implementation of multiplex POC diagnostics for infectious diseases.
