Hair testing has emerged as an invaluable method for detecting drug and alcohol consumption. Hair captures drug and alcohol traces over an extended period by embedding biomarkers in the fibers of growing strands. When sourced near the scalp, hair can reveal a history of alcohol and drug usage spanning roughly three months. Hair collection is straightforward, relatively tamper-proof, and convenient for transportation.
Acquiring around 200 hair strands (approximately the diameter of a #2 pencil) near the scalp gives roughly 100mg, which is optimal for screening and confirmation. For EtG, additional tests, or beyond 10 panels, 150mg is advisable. It is recommended to weigh the sample using a jeweler’s scale. Should scalp hair be lacking, a similar quantity of body hair is acceptable. The term head hair pertains specifically to scalp hair. Body hair encompasses all other hair types, such as facial and axillary.
Process Overview
The laboratory procedure for drug testing is comprised of four essential phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the preliminary handling of a specimen into the laboratory’s database. This phase ensures that the sample is properly sealed and shipped, assigns a randomly generated LAN (Laboratory Accessioning Number), and completes any extra data entry not included in an electronic chain of custody system.
Screening performs an initial swift assessment for commonly abused substances. Although Screening offers a cost-efficient solution for excluding drug consumption in most samples, positive screens require confirmation to be court-admissible. Any initially positive screenings necessitate further verification.
If a sample indicates a presumptive positive during Screening, additional hair is extracted from the initial sample for further preparation in Extraction. Here, drugs are isolated from hair in much lower concentrations than traditional methods (such as urine or oral fluid), making hair testing one of the most challenging methodologies to execute.
Verification of any positive screen is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing prior to confirmation as needed. The complete laboratory workflow from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and meets ISO / IEC 17025 accreditation standards.
