## Indications for Use

This in-vitro diagnostic method is intended to measure salicylate in human serum and plasma (lithium heparin as the anticoagulant) on ADVIA IMS. Measurements of salicylate are used in the diagnosis, monitoring and treatment of salicylate toxicity and overdose.

## Device Story

In-vitro diagnostic assay for use on Bayer ADVIA IMS system; measures salicylate concentrations in human serum or plasma (lithium heparin). Device processes patient samples to quantify salicylate levels; results used by clinicians to diagnose, monitor, and treat salicylate toxicity and overdose. Performance validated via correlation with predicate system and assessment of imprecision and interfering substances (bilirubin, hemoglobin, lipids).

## Clinical Evidence

Bench testing only. Correlation study (N=47) comparing ADVIA IMS to Abbott/TDx yielded regression Y=0.997X - 1.39 (R=0.996). Plasma vs. serum correlation (N=49) yielded Y=0.985X + 0.00 (R=0.988). Imprecision (Total CV%) ranged from 2.5% to 9.6% across levels 4.8-64.6 mg/dL. Interference testing performed for bilirubin, hemoglobin, and lipids.

## Technological Characteristics

In-vitro diagnostic reagent system for use on ADVIA IMS analyzer. Analytical range: 0-120 mg/dL. Methodology involves chemical assay for salicylate quantification. Performance characteristics validated against predicate; no specific materials or software architecture details provided.

## 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.

## Predicate Devices

- Abbott/TDx Salicylate ([K844070](/device/K844070.md))
