Clinical chemistry is the division of laboratory medicine that uses chemical methods to measure, determine, or analyze various biochemical measurands in clinical specimens such as blood, urine, and body fluids.
About more than half of the laboratory tests performed in most clinical laboratories are clinical chemistry tests. The test items include carbohydrates, proteins, vitamins, trace elements, lipids, enzymes, electrolytes, blood gases, cardiac markers, hormones, endocrine function tests, minerals, bone markers, therapeutic drugs, tumor markers, urine, genetic and molecular tests, etc.
Clinical chemistry involves a variety of disciplines, including laboratory informatics, laboratory statistics, quality control and management, and laboratory automation, standardization and harmonization.
For good laboratory practice, clinical chemistry professionals are frequently involved in evaluating the analytical performance of chemistry items.
