Journal ArticleDOI
Prostate-specific antigen in screening of prostate cancer.
TL;DR: Although the increase in the patient's survival due to PSA‐based detection of early prostate cancer remains to be documented, it is generally agreed that the PSA test along with digital rectal examination (DRE) should be included in the annual physical examination for men 50 years of age or older.

Validation of a 10-minute dipstick test for serum prostate-specific antigen.
TL;DR: This semiquantitative one-step PSA test is capable of distinguishing serum PSA levels with a cutoff value of 4.0 ng/ml with an overall concordance rate of 92.9%.

TL;DR: Three fluorophores, allophycocyanin (APC), carboxymethylindocyanine succinimidyl ester (C45) and fluorescein isothiocyanate (FITC), were evaluated in whole blood and serum assays using the fluorescence capillary fill device immunosensor and APC gave the best analytical performance.

Equivalent recognition of free and act‐complexed PSA in a monoclonal‐polyclonal sandwich assay is conferred by binding specificity of the monoclonal antibody
TL;DR: The Bayer Immuno 1TM PSA Assay measures free and ACT‐complexed PSA on an equimolar basis, although it uses a monoclonal antibody (MM1) for capture and polyclonal antibodies for detection, although the affinity constants of MM1 for both free PSA and PSA‐ACT are similar.
