Breast Milk Drug Testing
In 2008, the CDC reported that in the United States more than 70 percent of mothers breast feed their babies. This high level of participation is due to the growing list of health benefits provided to both the mother and the newborn.
The 2008 publication of data from the most recent National Survey on Drug Use and Health indicated that 5.2 percent of pregnant women had used illicit drugs in the month prior to the survey. In addition, 11.6 percent of pregnant women acknowledged alcohol consumption during pregnancy.
Most drugs of abuse readily pass into human breast milk. While therapeutic levels of prescription drugs may be considered compatible with breastfeeding, abuse levels may be problematic for the infant.
USDTL offers 5, 7, 9, 12 and 13 drug test panels in human breast milk. All presumptive specimens identified by our immunoassay screening are confirmed by LC/MS/MS or GC/MS. The method requires 10 mL of breast milk collected in a sterile container. Results will be provided in 2 to 3 days after the sample is received in the laboratory.

Does the sample need to be frozen?
How much breast milk is needed?
When will I receive breast milk results?
Why was one matrix positive and another negative on the same donor?
There are several explanations for this.
- Different sample matrices have different detection time frames. The result of any second collected specimen has no bearing on the validity of a first collected specimen. For example, a hair sample with a three month window of detection might test positive for a particular substance, while a urine sample from the same donor, with a 2-3 day window of detection, might test negative. In this case, the donor has used that substance within the past three months, but may not have used it within the most recent three days.
- The result of any second collected specimen has no bearing on the validity of a first collected specimen. Therefore, a negative result observed for the umbilical cord does not refute a positive result observed on the maternal urine specimen and the reverse is true as well. There are many legitimate reasons for discrepant urine and umbilical cord results.
- The urine specimen was a screen only result and was not confirmed using an appropriate mass spectrometric method. The screen only urine result is a clinically valid result, however, without an appropriate mass spectrometric confirmation, the urine result has no value in a forensic proceeding.
- Lastly, some placentas can prevent some compounds from reaching the fetus. There are documented cases of maternal ingestion without in utero exposure.
