Clinical Biochemistry is a special branch of medicine dealing with measurement and interpretation of the physicochemical condition and dynamics in healthy and diseased humans, thus contributing to a pathophysiological understanding and thereby to prophylaxis, diagnosis, therapy, prognostication and research of disease. Many diseases show significant changes in the chemical composition of body fluids such as the raised blood enzymes due to their release from heart muscles after a heart attack; or a raised blood sugar in diabetes mellitus due to lack of insulin. Biochemical tests are designed to detect these changes qualitatively or quantitatively compared to results from healthy people. Clinical biochemistry use a broad range of analytical techniques for example, molecular diagnostics, measurement of enzyme activities, spectrophotometry, electrophoresis, the separation of molecules based on physical characteristics and immunoassays. A journal is a periodical publication intended to further progress of science, usually by reporting new research. Most journals are highly specialized, although some of the oldest journals publish articles, reviews, editorials, short communications, letters, and scientific papers across a wide range of scientific fields.
