Intended use: Mycophenolic Acid Determination Kit is an in vitro diagnostic test for the quantitative detection of Mycophenolic Acid (MPA) in human serum and plasma specimen. This product is intended to be used by laboratory professional workers only. This kit is used for auxiliary diagnosis. Results must be combined with clinical observations, patient history, other laboratory parameters, and epidemiological information. Mycophenolic acid (MPA) is a commonly used immunosuppressant in organ transplantation. Free mycophenolic acid has pharmacological activity, and its metabolism is affected by many factors, resulting in individual differences in blood concentrations. Determine the content of mycophenolic acid in the human body, combining with patient’s individual characteristics and disease state, to design a dosing plan, which will provide reference for realizing individualized dosing in clinical practice, improving curative effect, and reducing adverse drug reactions.
