Clinical chemistry studies the molecular processes that underlie the development and functioning of organisms. Biochemistry uses the methods of "molecular" sciences - chemistry, physical chemistry, molecular physics, and in this respect biochemistry itself is a molecular science.
Clinical biochemistry is a section of clinical laboratory diagnostics whose main objectives are the quantitative and qualitative determination of biochemical parameters in biological fluids of the body, the study of the nature of changes in these indicators in pathology and a number of physiological states, as well as the development of methods for their determination.
Biochemical analysis of blood is aimed at determining the level of glucose, proteins and amino acids, nitrogenous substances, pigments, lipid composition, enzymes, vitamins, proteins, inorganic substances, including microelements. This blood test makes it possible to identify abnormalities in the liver and kidneys, the pathology of the cardiovascular system, the diagnosis of anemia, and the differential diagnosis of cancer.
