COCAINE METABOLITE

SPECIFIC PERFORMANCE CHARACTERISTICS

 

SENSITIVITY

 

The sensitivity of the AxSYM Cocaine Metabolite assay was calculated to be 30.00 ng/mL. This sensitivity is defined as the lowest measurable concentration which can be distinguished from zero at least 95% confidence.

 

SPECIFICITY

 

Cross-reactivity was tested for cocaine metabolites. The following compounds cross-react above the sensitivity (30.00 ng/mL) of the AxSYM Cocaine Metabolite assay:

The presence of detergents in samples potentially interferes with immunoassay results.

 

Bleach (hypochlorite) is a strong oxidizing agent. As a consequence, bleach may cause oxidation of some analytes, thus reducing the amount available for analysis. This may result in lower analytic results, regardless of the methodology.

 

There is the possibility that other substances and/or factors not listed above may interfere with the test and cause false results.
