Recognized as a robust approach, hair testing serves for identifying drug and alcohol consumption. Hair captures a prolonged history of such substances by embedding biomarkers within the texture of the hair strand as it grows. When trimmed closely to the scalp, it can reveal a detection period of up to roughly three months for substances like alcohol and drugs. The procedure for collecting hair is straightforward, relatively immune to tampering, and convenient for transportation.
A segment measuring 1.5 inches of about 200 hair strands (roughly the thickness of a #2 pencil) adjacent to the scalp yields about 100mg, deemed the ideal quantity for both screening and confirmation purposes. For screenings involving EtG, additional substances, or panels exceeding 10, a 150mg specimen is advised. Utilizing a jeweler’s scale to weigh the sample is suggested. Should scalp hair be unobtainable, an equivalent mass of body hair can suffice. Specifically regarding head hair, it pertains solely to scalp strands, while body hair encompasses all other varieties (such as facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test outcome involves four central phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to initially logging a specimen into the laboratory system. Tasks include validating the integrity of the sample's seal and shipment, allocating a unique LAN (Laboratory Accessioning Number), and fulfilling any additional data details not covered by an electronic chain of custody system.
Screening involves an expedited, preliminary verification for substance abuse. While it serves as an economical means to dismiss drug presence across most samples, positive findings require follow-up confirmation to hold legal weight. Samples flagged as presumptively positive during Screening necessitate further verification.
Upon identifying a sample as presumptively positive during Screening, additional hair is sourced from the primary specimen and groomed for Extraction. This phase denotes a lower concentration extraction of substances from hair, contrasting with other techniques (e.g., urine or oral fluid), making it the most challenging methodology in hair drug testing.
Verifying any screening results that are positive is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Before proceeding with confirmation, any presumptive positive samples undergo cleaning as required. The full lab process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair classification and under ISO / IEC 17025 standards.
