Part Description

LP96332-9 HIV 1+2 Ab+HIV1 p24
This test detects HIV-1 core protein, p24, antigen and/or HIV-1 groups M and O Ab and/or HIV-2 Ab in serum or plasma as one combined positive or negative result based on a signal to cut-off (S/CO) value of 1.00. The p24 antigen can be detected in HIV infected persons before seroconversion, thus reducing the window of non-detectability in early infection. Viral transmembrane proteins (TMP) are among the first to appear at seroconversion and remain strong throughout the asymptomatic and symptomatic stages of HIV infection. They are the principle target of HIV antibody tests. Source: Regenstrief Help Package Insert Regenstrief LOINC Example package insert. This LOINC code is not constrained to this specific product.
