Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. Hair strands preserve a prolonged record of substance use by embedding biomarkers within the hair fiber as it grows. When trimmed near the scalp, hair can reveal up to a three-month timeframe for detecting both alcohol and drugs. Hair collection is straightforward, quite resistant to tampering, and easily transportable.
A 1.5-inch sample comprising roughly 200 hair strands (comparable to the width of a #2 pencil) near the scalp generates 100mg of hair, which is optimal for screening and confirmation. For EtG, supplementary tests, or analysis exceeding 10 panels, 150mg of the sample is advised. Using a jeweler’s scale to weigh the sample is recommended. Should scalp hair be absent, an equivalent amount of body hair might be used. Head hair strictly refers to scalp hair, while body hair encompasses other types like facial and axillary hair.
Process Overview
The primary procedures in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step of integrating a sample into the laboratory's system, ensuring the sample is sealed and dispatched correctly, generating a random LAN (Laboratory Accessioning Number), and supplementing any extra data entry not covered by an e-chain of custody system.
Screening consists of an initial rapid assessment for drugs of misuse. Although Screening is a financially efficient way to exclude drug use in most samples, a positive screen must be verified for legal acceptance. Any samples with provisional positive results in Screening necessitate a follow-up confirmation.
Should a sample exhibit a presumptive positive in the Screening phase, additional hair is extracted from the initial sample to prepare for Extraction. During this phase, drugs are isolated from hair at markedly lower concentrations compared to other methods (such as urine or oral fluid), which makes hair drug screening particularly challenging to execute.
Confirmation of a positive screening result is done through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing before confirmation if required. The complete laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
