Buprenorphine, Meconium, Quantitative

Drugs Covered: Buprenorphine and norbuprenorphine.
Positive Cutoff: 20 ng/g

Meconium begins to form between the 12th and 16th week of gestation. Meconium drug testing can detect maternal drug use during the last 4 to 5 months of pregnancy. A negative result does not exclude the possibility that a mother used drugs during pregnancy. Detection of drug use depends on the quantity and quality of the specimen tested as well as the pattern and frequency of drug(s) used by mother. The concentration value must be greater than or equal to the cutoff to be reported as positive. Although not likely, the presence of drugs administered during labor and delivery may be detected in meconium. Interpretive questions should be directed to the laboratory.
