| Interpretive Data: |
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 the mother. Although not likely, drugs administered during labor and delivery may be detected in meconium. Interpretive questions should be directed to the laboratory.
The concentration at which the screening test can detect a drug or metabolite varies within a drug class. The concentration value must be greater than or equal to the cutoff to be reported as positive.
For medical purposes only; not valid for forensic use.

| Note: |
If the specimen screens positive, then Confirmation/Quantitation by GC/MS and/or LC-MS/MS will be added to confirm result. Additional charges apply.
Unless ARUP is otherwise notified, reflex confirmation testing will be performed in the following order of priority:
Amphetamines (0.125 g sample required)
Cocaine (0.5 g sample required)
Opiates (0.125 g required)
Marijuana (0.125 g required)
Benzodiazepines (0.5 g sample required)
Methadone (0.125 g sample required)
Propoxyphene (0.125 g sample required)
Phencyclidine - PCP (0.5 g sample required)
Barbiturates (0.5 g sample required)
