biokeemilistest

Biokeemilistest is a term used in laboratory sciences to describe a broad class of biochemical assays and tests that quantify or characterize biological molecules and enzymatic activities. In practice, it covers methods designed to detect, measure, or profile metabolites, enzymes, proteins, and other biomolecules in biological samples. The term is used in regional or occupational contexts and generally aligns with clinical chemistry and biochemical analytics.

Methods within biokeemilistest include colorimetric and fluorometric assays, immunoassays such as ELISA, chromatography-based analyses (high-performance liquid chromatography and gas chromatography–mass spectrometry), and mass spectrometry–based workflows. Emerging approaches also involve biosensors and microfluidic-based platforms. Sample types span blood, urine, tissue extracts, cell culture media, and environmental or food matrices, reflecting the field’s broad applicability.

Applications of biokeemilistest encompass clinical diagnostics (for example, measuring glucose, lipids, liver enzymes), therapeutic drug monitoring, biomarker discovery, and profiling in proteomics and metabolomics. They support quality control in pharmaceutical development, food safety testing, and environmental surveillance.

Quality and standards in biokeemilistest rely on calibration curves, appropriate controls, and adherence to QA/QC procedures. Laboratories often follow guidelines from professional bodies and accreditation schemes to ensure accuracy and traceability. Limitations can include matrix effects, cross-reactivity, instrument requirements, and the need for specialized expertise.

Etymology and usage note: in some languages, the term corresponds to “biochemical tests” and is used descriptively rather than as a formal, singular discipline. See also clinical chemistry, analytical chemistry, and biomarker assays.
