## Indications for use
For the quantitative determination of salicylate in serum. For IN VITRO diagnostic use. Salicylate is a common drug used for its analgesic and anti-inflammatory properties. Its accessibility leads to its implication in a large number of accidental ingestions by children and it is a common choice among adults and adolescents for attempted suicidal poisoning. (1) Salicylate overdose results in disturbances of the central nervous system and the gastrointestinal tract as well as encephalopathy and renal failure. It represents an acute medical emergency and rapid quantitation of the drug is necessary for effective patient management. (2) Salicylate has been traditionally measured by the "Trinder Reaction" which is based on the interaction between salicylate and ferric ions. This test however is not specific and requires extraction or centrifugation which inhibit the automation of the test. This enzymatic Salicylate Assay provides a rapid, specific and simplified method for salicylate determination. It is based on the action of salicylate hydroxylase on salicylate and NADH which results in a decrease in absorbance proportional to the amount of salicylate present. (3) The test can be adapted to automated instruments resulting in rapid, accurate results required by physicians.
