Hair testing is increasingly recognized as a robust method for detecting alcohol and drug use. The fibers of the hair strand capture biomarkers, offering a comprehensive history of substances consumed. When collected near the scalp, hair can provide evidence of alcohol and drug use for up to about three months. Collection is straightforward, adulteration is challenging, and shipping is uncomplicated.
A sample measuring 1.5 inches of approximately 200 strands of hair, comparable to the diameter of a #2 pencil, yields 100mg, perfect for both screening and verification. For EtG, additional tests, or tests exceeding 10 panels, a 150mg sample is suggested. We advise using a jeweler's scale for weight accuracy. If scalp hair isn't available, body hair in an equivalent amount can be collected. "Head hair" is defined specifically as scalp hair, while "body hair" includes all other types (e.g., facial, axillary).
Process Overview
The laboratory's processing of drug test results encompasses four critical stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step, where a sample is integrated into the lab's system, involving the verification of proper sealing and shipping, assigning a unique Laboratory Accessioning Number (LAN), and completing any data entry not captured by electronic custody systems.
Screening serves as a preliminary check for drugs of abuse. While it's an affordable method to exclude drug use for most samples, a positive Screening result necessitates confirmation to be court-admissible. Samples with presumptive positive results require additional confirmation.
If a sample shows presumptive positivity during Screening, further hair is extracted from the original sample to prepare for Extraction. At this stage, drug concentrations are extracted from hair at lower levels compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.
Confirmation of positive Screening results is performed using techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleaned before confirmation as appropriate. The entire lab process from Accessioning to Confirmation undergoes review per both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.
