-
Immunoassay reagents intended to perform qualitative and/or quantitative analyses on a body fluid sample (usually whole blood) to determine in a short period of time (typically several minutes) the prostate specific antigen (PSA) enzyme, either total or free (fPSA). Measurements of PSA level are used in monitoring treatment of prostate carcinoma because it correlates with the stages of tumor extension and metastasis and indicates success of treatment. The level of total and/or free PSA, and the proportion of free to total PSA can be used to help differentiate benign prostatic hyperplasia and prostate carcinoma.
