Hair analysis is recognized as an effective means for identifying the use of drugs and alcohol. The fibers of a growing hair strand entrap markers, allowing hair to present a comprehensive history of drug and alcohol use. When obtained near the scalp, hair can indicate the usage of alcohol and drugs for up to roughly three months. It's straightforward to gather hair samples, challenging to tamper with, and simple to transport.
A sample of 1.5 inches in length, composed of about 200 hair strands (approximately comparable to a #2 pencil's diameter) near the scalp, provides 100mg, which is optimal for both screening and confirmation processes. For EtG, additional tests, and/or assessments exceeding 10 panels, a minimum of 150mg of hair is suggested. It's advisable to measure the sample's weight using a jeweler’s scale. Should scalp hair be unavailable, a matching quantity of body hair can be used. The term "head hair" pertains solely to scalp hair, whereas "body hair" encompasses all other types of hair (facial, armpit, etc.).
Process Overview
The laboratory procedure for processing a drug test comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial integration of a sample into a laboratory's system. This process ensures the sample's proper sealing and shipment, assigns a unique LAN (Laboratory Accessioning Number), and completes any remaining data entry not covered by an electronic chain of custody system.
Screening serves as a preliminary, rapid assessment for drugs of abuse. Though this method economically excludes drug use in most samples, a positive screening result requires confirmation to be legally admissible. Any samples flagged as presumptively positive during Screening must undergo additional confirmation.
If Screening indicates a presumptive positive result, additional hair is drawn from the original sample for Extraction. This stage entails extracting drugs from hair at considerably lower concentrations compared to other techniques (such as urine or oral fluid), underscoring the complexity of hair drug screening.
Confirming a positive screening result is carried out using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples with presumptive positive results are thoroughly washed as necessary. The entire laboratory process—from Accessioning to Confirmation—adheres to both the CAP (College of American Pathologists) Hair designation and accreditation standards of ISO / IEC 17025.
