What is it indicated for?

The UPlink™ Oral Fluid Drug Test is a rapid immunoassay intended for use with the UP/ink™ Analyzer for the qualitative detection of opiates in oral fluid using a 40 ng/mL cutoff. FOR IN VITRO DIAGNOSTIC USE.

The UPlink™ Test System provides only a preliminary analytical test result. A more specific alternate chemical method must be used in order to obtain a confirmed analytical result. Gas chromatography/mass spectrometry (GC/MS) is the preferred confirmatory method. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when a preliminary, positive result is observed.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
