## Indications for Use

For the quantitative determination of salicylate in serum. For IN VITRO diagnostic use.

## Device Story

Salicylate-SL Assay is an in vitro diagnostic reagent for quantitative measurement of salicylate in serum. It addresses clinical needs for rapid salicylate detection in cases of accidental ingestion or suicidal poisoning. Unlike traditional Trinder Reaction methods requiring extraction or centrifugation, this enzymatic assay uses salicylate hydroxylase to react with salicylate and NADH. The reaction causes a decrease in absorbance proportional to salicylate concentration. Designed for use on automated clinical laboratory instruments, it provides rapid, specific results to assist physicians in managing acute medical emergencies involving salicylate overdose, such as CNS disturbances, encephalopathy, and renal failure.

## Clinical Evidence

No clinical data provided; bench testing only.

## Technological Characteristics

Enzymatic assay utilizing salicylate hydroxylase. Principle: decrease in NADH absorbance proportional to salicylate concentration. Form factor: liquid reagent for automated clinical chemistry analyzers. Intended for in vitro diagnostic use.

## Regulatory Identification

A salicylate test system is a device intended to measure salicylates, a class of analgesic, antipyretic and anti-inflammatory drugs that includes aspirin, in human specimens. Measurements obtained by this device are used in diagnosis and treatment of salicylate overdose and in monitoring salicylate levels to ensure appropriate therapy.

Device Name: Salicylate-SL Assay _____________________________________________________________________________________________________________________________________________

## 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.
