Hair analysis is widely regarded as an effective method for identifying alcohol and drug consumption. Hair acts as a historical record for substances by embedding biomarkers within the strands as they grow. Obtained from near the scalp, hair can reflect alcohol and drug usage for up to a three-month period. It is easy to collect, hard to tamper with, and simple to transport.
A 1.5-inch segment from about 200 hair strands (approximately the width of a #2 pencil) taken closest to the scalp provides 100mg of hair, the optimal sample for both screening and confirmation. For EtG, additional tests, or panels exceeding 10, a 150mg sample is recommended. It's suggested to use a jeweler’s scale to weigh the sample. If scalp hair isn't available, an equivalent amount of body hair can be taken. Note that head hair refers specifically to scalp hair, while body hair includes facial, axillary, and other types.
Overview of Procedure
The laboratory processing of a drug test involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where a sample is formally registered in a lab's system, involving checks for proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody system.
Screening involves a preliminary evaluation for drug presence. While Screening serves as a cost-efficient method to exclude drug use for most samples, a positive screening result requires confirmation for legal admissibility. All samples testing presumptively positive in Screening necessitate further confirmation.
For samples indicated as presumptively positive during Screening, additional hair is extracted from the original sample for the Extraction phase. At this point, substances are isolated from the hair at much lower concentrations than other testing methods (like urine or oral fluid), contributing to the complexity of performing hair drug tests.
Any confirmed positive result from the Screening process is verified using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive findings undergo washing prior to confirmation if needed. The complete laboratory process from Accessioning through Confirmation is validated under both the CAP (College of American Pathologists) Hair designation and accreditation per ISO / IEC 17025 standards.
