The utilization of hair testing has emerged as an effective means for identifying drug and alcohol consumption. Hair captures a prolonged timeline of alcohol and drug presence by encapsulating biomarkers within the strands as they grow. Collected near the scalp, hair offers a potential detection window of around three months for both alcohol and drugs. The collection process for hair samples is straightforward, challenging to tamper with, and convenient for transportation.
A sample measuring 1.5 inches, consisting of approximately 200 hair strands (comparable to a #2 pencil's thickness) nearest to the scalp, provides 100mg of hair—ideal for analysis and verification. For tests like EtG, additional tests, or panels exceeding 10, a 150mg sample is preferable. Using a jeweler’s scale to weigh the sample is advised. In cases where scalp hair is inaccessible, a comparable quantity of body hair can be obtained. References to head hair specifically imply scalp hair. Body hair encompasses all other types such as facial and axillary hair.
Process Overview
The laboratory analysis of a drug test involves four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary integration of a sample into the laboratory's database. This phase involves checking that the sample was appropriately sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry not captured by an electronic chain of custody system.
In the Screening phase, an initial rapid assessment for drug use is conducted. While Screening offers a cost-efficient approach to ruling out drug use in most samples, confirmation of a positive screen is necessary for legal acceptability. Samples with a preliminary positive result in Screening require an additional confirmation.
Should a sample be preliminarily positive during the Screening phase, further hair is extracted from the original sample to prepare for Extraction. During Extraction, drugs are isolated from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid). This complexity is why hair drug analysis is among the most challenging methodologies to execute.
For any positive screening results, Confirmation is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Prior to confirmation, all presumptive positive specimens are washed as necessary. The entire laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair parameters and the ISO / IEC 17025 accreditation standards.
