Modern HIV diagnostics have evolved significantly, enabling earlier detection, improved accuracy, and greater accessibility. Today’s tests range from rapid point-of-care kits to highly sensitive laboratory assays that detect viral RNA, antigens, and antibodies. Fourth-generation tests, which simultaneously detect HIV-1/2 antibodies and p24 antigen, dramatically shorten the diagnostic window, allowing infections to be identified within two to three weeks.

Molecular techniques such as nucleic acid amplification testing (NAAT) are considered the gold standard for early detection, viral load monitoring, and treatment optimization. These tests are crucial for preventing mother-to-child transmission and assessing therapeutic effectiveness in patients receiving antiretroviral therapy.

Self-testing kits have expanded accessibility by allowing individuals to test privately and conveniently. Digital diagnostics integrated with mobile apps support counseling, linkage to care, and real-time data reporting. Emerging innovations, such as microfluidic devices, biosensors, and CRISPR-based detection systems, promise faster results, lower costs, and improved sensitivity for early infection and drug-resistant strains.

Together, these advancements contribute to global HIV control efforts by supporting early diagnosis, timely treatment initiation, and viral suppression.
