Intended use: Digoxin Determination Kit is an in vitro diagnostic test for the quantitative detection of Digoxin (DIG) 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. Digoxin is a cardiac glycoside drug, which is mainly used in the clinical treatment of congestive heart failure and high-volume atrial flutter caused by atrial fibrillation. However, this drug has a narrow therapeutic window and large individual differences. Even conventional doses may cause poisoning such as vomiting, nausea, palpitations, and chest tightness. Therefore, it is of great significance to detect the blood concentration of digoxin to ensure the safety of clinical medication.
