Recognized as an essential method for identifying drug and alcohol use, hair testing captures a historical record by embedding biomarkers in the strands as they grow. Sampling hair near the scalp can deliver a detection range of up to roughly three months for alcohol and drugs. The process of collection is straightforward, challenging to tamper with, and convenient for transport.
Collecting a 1.5-inch section consisting of approximately 200 hairs (akin to a #2 pencil's diameter) nearest to the scalp yields 100mg—ideal for screening and verification. For assessments including EtG, more than 10 panels, or additional options, a 150mg sample is suggested. It's advisable to measure the sample using a jeweler’s scale. When scalp hair cannot be obtained, a comparable quantity of body hair is suitable. Reference to head hair implies scalp hair alone. Body hair encompasses other types like facial or axillary hair.
Process Overview
The laboratory process for a drug test involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial sample processing within a laboratory's framework. This encompasses confirming proper sealing and shipment of the sample, generating a random LAN (Laboratory Accessioning Number), and completing any outstanding data input not covered by an electronic chain of custody mechanism.
Screening performs an initial identification for substance misuse. Although Screening is budget-friendly and rules out drug presence for most samples, any positive screen must be confirmed for legal acceptance. Presumptive positives in Screening necessitate subsequent confirmation.
Should a sample indicate a presumptive positive in Screening, more hair is extracted from the initial sample for the Extraction stage. Here, drugs are isolated from hair in significantly lesser concentrations compared to other methods (e.g., urine or oral fluid), underscoring why hair drug testing is among the most challenging methodologies.
Confirmation of screening positives employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing before confirmation where appropriate. From Accessioning to Confirmation, the laboratory procedure is scrutinized under the CAP (College of American Pathologists) Hair criteria besides ISO / IEC 17025 accreditation.
