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.

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.

CAM tests are not covered by health insurance. [6] The number of CAM laboratories is unknown and the sales of supplemental remedies based on the results of these tests is unknown. [11] Since CLIA does not regulate the clinical validity/usefulness of a test, it is possible for a CLIA laboratory to offer tests that have no clinical utility. [8] [12]
An example of a Levey–Jennings chart with upper and lower limits of one and two times the standard deviation. A Levey–Jennings chart is a graph that quality control data is plotted on to give a visual indication whether a laboratory test is working well.
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 ...
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 ...
NGS assays, however, are still at an early stage in clinical diagnostics. [48] To do the molecular diagnostic test for cancer, one of the significant issue is the DNA sequence variation detection. Tumor biopsy samples used for diagnostics always contain as little as 5% of the target variant as compared to wildtype sequence.
