What is it indicated for?
Syntron’s QuikStrip One Step Amphetamine assay is a rapid, qualitative, com@etitive binding immunoassay for the determination of Amphetamine in urine. The test provides only preliminary data which should be confirmed by other methods such as gas chromatograp]i;ylmass spectrophotometry (GC/MS). Clinical considerations and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are indicated®. Syntron’s QuikStrip One Step Amphetamine Test is not inténded to monitor drug levels, but only to screen urines for the presen¢e of amphetamine and its metabolites.
Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
