A clinical chemistry analyzer; hand shows size. Clinical chemistry (also known as chemical pathology, clinical biochemistry or medical biochemistry) is a division in medical laboratory sciences focusing on qualitative tests of important compounds, referred to as analytes or markers, in bodily fluids and tissues using analytical techniques and specialized instruments. [1]
Other clinical immunoassays are quantitative; they measure amounts. Immunoassays can measure levels of CK-MB to assess heart disease, insulin to assess hypoglycemia , prostate-specific antigen to detect prostate cancer , and some are also used for the detection and/or quantitative measurement of some pharmaceutical compounds (see Enzyme ...
A medical test is a medical procedure performed to detect, diagnose, or monitor diseases, disease processes, susceptibility, or to determine a course of treatment. Medical tests such as, physical and visual exams, diagnostic imaging, genetic testing, chemical and cellular analysis, relating to clinical chemistry and molecular diagnostics, are typically performed in a medical setting.
Clinical laboratory in a hospital setting showing several automated analysers. A medical laboratory or clinical laboratory is a laboratory where tests are conducted out on clinical specimens to obtain information about the health of a patient to aid in diagnosis, treatment, and prevention of disease.

The sample probably is the substance. For example, the Kastle–Meyer test will show either that a sample is not blood or that the sample is probably blood, but may be a less common substance. Further chemical tests are needed to prove that the substance is blood. Confirmatory tests are the tests required to confirm the analysis. Confirmatory ...
An assay (analysis) is never an isolated process, as it must be accompanied with pre- and post-analytic procedures. Both the communication order (the request to perform an assay plus related information) and the handling of the specimen itself (the collecting, documenting, transporting, and processing done before beginning the assay) are pre-analytic steps.
For example, the ColoGuard test may be used to screen people over 55 years old for colorectal cancer. [57] Cancer is a longtime-scale disease with various progression steps, molecular diagnostics tools can be used for prognosis of cancer progression. For example, the OncoType Dx test by Genomic Health can estimate risk of breast cancer.
Clinical chemistry: an automated blood chemistry analyser. Clinical pathology is a medical specialty that is concerned with the diagnosis of disease based on the laboratory analysis of bodily fluids , such as blood , urine , and tissue homogenates or extracts using the tools of chemistry , microbiology , hematology , molecular pathology , and ...
