New Fee Code: JA063 (CPT 80307)
Effective November 19, 2024, the MLabs Chemistry Laboratory will begin performing the Buprenorphine, Urine, Qualitative Screen assay using the Roche Cobas C automated analyzer. This method utilizes an enzyme immunoassay, replacing the current lateral flow immunoassay test strip. The threshold for detecting buprenorphine will be lowered from 10 ng/mL to 5 ng/mL with the Roche method.
The screening assay provides a Positive or Negative presumptive result. The Buprenorphine and Metabolites, Urine, Quantitative LC-MS/MS assay (order code UBUPM) remains available for confirmatory testing.
