nameMethadone [Z-score] in Urine
descriptionThis term represents the patient's drug level normalized for urine creatinine and lean body mass. It was created for, but not limited in use to, the Ameritox Medication Monitoring system, which assesses a patient's medication compliance by comparing the patient's result to a reference database of results from chronic pain patients who were known to be adherent to their medication regimen. In order to compare to the reference database, the patient's result is first normalized based on urine creatinine and lean body mass using a proprietary algorithm, and then the normalized result is converted to a Z-score based on the reference population.
