LOINC description : Qualitative confirmation of mitragynine in urine. Submitter's referral laboratory
uses what is usually considered a confirmatory method (e.g. LC/MS/MS) as the initial
method for this analyte and then will repeat the measurement with the same high accuracy
method on tests that are positive in the first run to confirm them. Results (e.g.
positive/negative) are based on a threshold of 1.0 ng/mL.;
