Hair analysis is now recognized as an effective means for identifying drug and alcohol use. Hair captures a prolonged history of substance intake by embedding biomarkers within the fibers of the hair strand as it grows. When hair is taken close to the scalp, it can offer roughly a 3-month period for detecting alcohol and drugs. Hair collection is straightforward, relatively tough to tamper with, and convenient to transport.
Acquiring a 1.5-inch segment consisting of around 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is optimal for both screening and verification. For tests involving EtG, additional screenings, or those exceeding 10 panels, 150mg of the sample is advisable. It's suggested to measure the sample using a jeweler's scale. If scalp hair is not accessible, a similar amount of body hair may be used. When discussing head hair, it refers solely to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Outline
The key stages in processing a drug test result in the lab involve Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes entering a sample into a laboratory system initially. This phase checks if the sample was securely sealed and shipped, allocates a random LAN (Laboratory Accessioning Number), and finalizes any supplementary data entry not covered by an electronic chain of custody system.
Screening involves a preliminary rapid assessment for substances of abuse. Although Screening is an economical means to discount drug usage in most samples, a positive result requires confirmation to hold up in a legal context. Any samples presumed positive in Screening necessitate a subsequent confirmation.
Should a sample be tentatively positive during the Screening phase, more hair is extracted from the primary specimen and readied for Extraction. At this phase, substances are extracted from hair at a significantly lower concentration than using other techniques (e.g., urine or oral fluid), which is why hair drug analysis is most challenging.
Confirmation of any positive screening outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Prior to confirmation, all samples presumed positive are washed as needed. The full lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.
