4th Generation Lab-Send Test (Biophan / myLAB Box)
Best Overall — Earliest Detection, Highest Sensitivity
Fourth-generation antigen/antibody combination tests are the most sensitive HIV tests available outside a clinical setting — detecting HIV-1, HIV-2, and the p24 antigen, which appears 5–10 days before antibodies. This extends detection to as early as 18 days post-exposure vs 23+ days for antibody-only tests. The finger-prick sample is mailed to a CLIA-certified laboratory and results arrive via secure encrypted portal within 1–3 business days. All positive results include automatic connection to a counselor and guidance on next steps.
