This is the most advanced and reliable screening test available for HIV. Our 4th Generation HIV test is the gold standard because it detects both the HIV antibodies and the p24 antigen. The p24 antigen appears before antibodies, allowing this test to detect an infection in a much earlier "window period" than older tests. It requires a simple blood draw. Early detection is everything. This advanced test provides the fastest, most accurate, and conclusive answer, giving you definitive peace of mind and the power to take control of your health.
