In November 2002, the OraQuick Rapid HIV-1/2 Antibody Test was FDA-approved and was CLIA-waived shortly after in January 2003, permitting diagnosis of HIV in a non-clinical setting . Detection of anti-HIV antibodies by rapid PoC test remains the mainstay of testing algorithms across many settings, with high levels of the target molecules (up to
