OPIATES CONFIRMATORY/ DEFINITIVE, URINE, BY LC-MS/MS
Message- Definitive compliance checks in patients prescribed codeine, dihydrocodeine, hydrocodone, hydromorphone, morphine, oxycodone, and/or oxymorphone
- Confirming presumptive positive screening tests for opiates. [Urine quantitative values do NOT correlate well with serum concentrations and should not be used for assessing dose efficacy or timing.]
Test Code
LAB1230610
CPT Codes
80307
Includes
Quantitative/definitive detection of opiates that can cross-react and yield positive opiate screening results. Quantitative results are only provided for positive results; negative results will have an interpretation of “Negative” and a component result of “Not detected”. [Urine quantitative values do NOT correlate well with serum concentrations and should not be used for assessing dose efficacy or timing.]
Adulteration testing is provided at no-charge and includes urine creatinine
