Testing Algorithm
Testing begins with a screening assay. If the buprenorphine screen is positive, then the liquid chromatography tandem mass spectrometry confirmation with quantification will be performed at an additional charge.
Method Name
Immunoassay
Reporting Name
Buprenorphine Screen w/Reflex, USpecimen Type
UrineOrdering Guidance
For screening buprenorphine alone, order BUPS / Buprenorphine Screen, Random, Urine.
For comprehensive opioid screening, order TOSU / Targeted Opioid Screen, Random, Urine.
For situations where chain of custody is required, a Chain of Custody Kit (T282) is available. For chain-of-custody testing, order BUPMX / Buprenorphine and Norbuprenorphine, Chain of Custody, Random, Urine.
Additional Testing Requirements
If urine creatinine is required or adulteration of the sample is suspected, the following test should also be ordered, ADULT / Adulterants Survey, Random, Urine.

Method Description
This assay is a homogeneous enzyme immunoassay technique. The assay will be performed semi-quantitatively. The assay is based on competition between free drug in the urine sample, and a drug labeled with the enzyme glucose-6-phosphate dehydrogenase for a fixed amount of specific antibody binding sites. Active enzyme reduces nicotinamide adenine dinucleotide (NAD[+]) to NADH, which results in an absorbance change that can be measured spectrophotometrically at 340nm. Similar testing is being performed on the Olympus AU680 analyzer and this test would be an addition to the current testing.(Package insert: Buprenorphine Urine Enzyme Immunoassay.
