Hair analysis is now recognized as an effective means for identifying alcohol and drug consumption. By embedding biomarkers within the hair's fibers, hair offers an extended timeline of substance usage. When harvested close to the scalp, it can present a detection timeframe of up to around 3 months for alcohol and drugs. Hair is straightforward to gather, moderately tamper-resistant, and simple to send.
A 1.5-inch section, consisting of approximately 200 hair strands (equivalent to a #2 pencil's thickness) nearest to the scalp provides 100mg of hair, the optimal quantity for both screening and validation. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is advised. It is suggested to weigh the sample using a jeweler’s scale. If scalp hair isn’t available, a similar quantity of body hair can be acquired. While mentioning head hair, it refers solely to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The procedure of laboratory drug testing consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the sample’s initial processing into a lab's system. This step includes checking that the sample was adequately sealed and sent, assigning an arbitrary LAN (Laboratory Accessioning Number), and executing any additional data entry not covered by the electronic chain of custody system.
Screening entails an initial rapid assessment for drug abuse indicators. While Screening is a cost-efficient method to exclude drug usage across most samples, a positive screen must be verified to be legally accepted. Any samples that show presumptively positive results in Screening require a secondary verification.
Should a sample test presumptively positive during Screening, more hair is extracted from the original specimen and readied for Extraction. Here, drugs are isolated from hair at much lower concentrations compared to other methods (such as urine or oral fluid), which is why hair drug analysis is the most challenging methodology to execute.
Verification of any positive screening result is performed through GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation if required. The comprehensive laboratory operation from Accessioning to Confirmation is scrutinized both under the CAP (College of American Pathologists) Hair designation and the compliance with ISO / IEC 17025 benchmarks.
Advantages of hair drug testing:
Limitations:
Note: Although frequently termed "hair follicle tests", the analysis actually examines the hair strand rather than the underlying hair follicle.
