Hair testing is now recognized as an effective means for identifying drug and alcohol use. Hair offers a long-term record of alcohol and drug presence by embedding biomarkers within the hair strand's fibers as it grows. When taken near the scalp, hair can indicate alcohol and other drug use for nearly 3 months. Hair is easy to collect, moderately resistant to tampering, and straightforward to send off.
A 1.5-inch hair sample consisting of roughly 200 strands (akin to the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional tests, or panels above 10, 150mg of the sample is suggested. Using a jeweler's scale to weigh the sample is advised. If there is no scalp hair available, a similar amount of body hair can be taken. By head hair, we refer specifically to scalp hair. Body hair covers all other types (facial, axillary, etc.).
Process Overview
The laboratory processing for a drug test result comprises four major stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a lab's database. This step includes confirming the proper sealing and shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any further required data entry if not provided electronically.
Screening serves as a preliminary check for abused substances. While Screening is economical for negating drug use in most samples, a positive Screening requires confirmation for judicial acceptance. Presumptive positives identified during Screening necessitate a further confirmation step.
Should Screening yield a presumptive positive, additional hair is extracted from the primary sample and readied for Extraction. In this phase, drugs are removed from hair at significantly lower concentrations than in alternatives (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.
Postive screenings are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS methods. Prior to confirmation, all samples that tested presumptively positive are washed if required. The entire process, from Accessioning through Confirmation, undergoes thorough review in accordance with the CAP Hair guidelines and ISO/IEC 17025 accreditation standards.
