Recognized as highly effective, hair testing is utilized for identifying drug and alcohol consumption. Hair strands capture biomarkers within their fibers, offering an extended overview of alcohol and drug usage. Collected near the scalp, hair samples provide roughly a 3-month period for detection. Hair sampling is straightforward to gather, relatively immune to tampering, and convenient to transport.
A sample measuring 1.5 inches, consisting of roughly 200 hair strands (comparable to the width of a #2 pencil) nearest to the scalp provides 100mg of hair, the optimal quantity for screening and verification. For EtG, additional tests, and/or panels exceeding ten, a 150mg specimen is advised. It is recommended to employ a jeweler’s scale for precise weighing. Should scalp hair be inaccessible, a similar quantity of body hair might be utilized. 'Head hair' specifically refers to scalp hair, whereas 'body hair' encompasses all other variants (facial, axillary, etc.).
Process Overview
The core stages of laboratory drug test processing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the introductory assessment of a sample integrated into a laboratory’s system. This covers the verification of proper sample sealing and shipment, allocation of a unique LAN (Laboratory Accessioning Number), and any supplementary data entry absent in an electronic chain of custody framework.
Screening offers an initial rapid drug check. Though cost-efficient for excluding drug use in most samples, a positive screen necessitates confirmation to hold in legal proceedings. Samples exhibiting presumptive positives in Screening require further verification.
Specimens flagged as presumptively positive during Screening have additional hair sourced for Extraction. During Extraction, drugs are retrieved from hair at substantially lower concentrations compared to other methodologies (such as urine or oral fluid), emphasizing the complexity in executing hair drug analysis.
A positive screening result is verified through methods like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before Confirmation as warranted. The comprehensive lab process spanning Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.

Limitations:
Note: Commonly referred to as "hair follicle tests", this test examines the hair strand, not the follicle beneath the scalp.
