Test reagent/measurement device. The Lumipulse Presto HIV-Ag/Ab (Presto) is a reagent used in a chemiluminescent enzyme immunoassay (CLEIA) with a two-step sandwich method. Presto can detect HIV-1/2 antibodies and HIV-1 p24 antigen in the serum or plasma. A complex is formed by two components; HIV-1 recombinant antigen (gp41), HIV-2 recombinant
Jan 1, 2020 · Criteria for interpretation of a positive test result for HIV -1 include the presence of any two bands of the HIV-1 test lines with at least one envelope band positive (gp160 or gp41), while a positive test for HIV-2 must include both HIV-2 bands (gp36 and gp140). Testing of this patient’s sample using this assay produced a faint band in the
