Because of the confusion that occurs in countries that report results as both decimal fraction and percent, this property was created to represent decimal fractions that are reported without units.
This term was created for, but is not limited in use to, bioMerieux's VIDAS FPSA assay, which is intended for the quantitative measurement of the free fraction of prostate specific antigen (PSA) in human serum or plasma.
Prostate-specific antigen (PSA) is a protein produced by the prostate gland. This test measures PSA levels in peritoneal fluid (fluid in the abdomen), which may be performed in advanced prostate cancer cases to assess disease spread or progression. Elevated PSA in peritoneal fluid can indicate metastatic disease. PSA testing is part of prostate cancer screening and monitoring, particularly in men with a family history or those experiencing urinary symptoms. Results should be interpreted alongside other clinical findings.
