Glossary Term
A program for the determination of laboratory performance where individual labs perform the same test on the same or similar items or materials, with the results from each lab compared and evaluated.
Tests
The determination of the proliferating cell nuclear antigen present in a sample.
Glossary Term
A DNA sequence at which RNA polymerase binds and initiates transcription.
Article
Research record from Sci Rep, 2026-04-08. PMID 41951723.
Glossary Term
A type of study in which participants are enrolled into the study before they develop the disease or outcome in question.
Tests
The determination of the amount of prostate cancer antigen 3 mRNA in a biological sample.
Tests
The determination of the amount of prostate specific antigen mRNA in a biological sample.
Tests
A protein produced by prostate tissue; elevated values can reflect prostate cancer but also common benign conditions.
Glossary Term
Refers to the total protein-encoding capability of an organism's genome. It is also used to refer to the actual total expressed protein complement of an organism or to the identifiable proteins of a single tissue or cell type or subcellular compartment.
Glossary Term
The global analysis of cellular proteins. Proteomics uses a combination of sophisticated techniques including two-dimensional (2D) gel electrophoresis, image analysis, mass spectrometry, amino acid sequencing, and bio-informatics to resolve comprehensively, to quantify, and to characterize proteins. The application of proteomics provides major opportunities to elucidate disease mechanisms and to identify new diagnostic markers and therapeutic targets.

Indicators
Prostate-specific antigen — a prostate tissue protein whose blood level rises in prostate cancer and in common benign conditions.
