Description

technical field [0001] The invention relates to the technical fields of medicine and biochemistry, in particular to an adenosine deaminase assay kit. Background technique [0002] Adenosine deaminase (adenosine deaminase, ADA) is an important enzyme in purine nucleoside metabolism. Its activity is a sensitive indicator reflecting liver damage and can be used as one of the routine inspection items of liver function. The determination of ADA activity in serum can be used to: judge acute liver injury and residual disease; assist in the diagnosis of chronic liver disease; help in the diagnosis of liver fibrosis; help in the identification of jaundice. In addition, ADA deficiency is related to severe combined immunodeficiency disease (SCID), which can be used as an important enzyme in nucleic acid metabolism; ADA deficiency can lead to nucleic acid metabolism disorders, affect the development of thymus, and cause immune dysfunction. CSF ADA detection can be used as an important...
