Hair analysis is increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair captures a prolonged record of substance use by embedding biomarkers within the fibers of the hair as it grows. When cut near the scalp, hair can offer a detection timeframe of up to around three months for alcohol and other substances. Hair is straightforward to gather, relatively hard to tamper with, and convenient to transport.
A 1.5-inch piece comprising roughly 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp will provide 100mg of hair, which is the optimal sample for both screening and verification. For EtG, additional analyses, and/or tests over 10 panels, 150mg of the specimen is advised. We suggest using a jeweler’s scale to measure the specimen's weight. If head hair is not available, a similar quantity of body hair might be collected. In terms of head hair, we refer exclusively to scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The primary stages involved in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample within a lab’s system. This process involves ensuring the sample was correctly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and conducting any extra data entry not available from an electronic chain of custody system.
Screening is an initial rapid check for the presence of drugs. Though Screening is an economical approach to exclude drug intake in most samples, a positive result must be confirmed for court admissibility. Any samples with presumptive positive results in Screening must undergo further confirmation.
If a sample results in a presumptive positive during Screening, more hair is extracted from the initial sample and readied for Extraction. At this stage, drugs are extracted from hair at a much finer concentration than other methods (e.g., urine or oral fluid), making hair drug analysis the most complex method to undertake.
Confirmation of any positive Screening result is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are cleaned prior to confirmation as required. The entire laboratory procedure from Accessioning to Confirmation is conducted under both the CAP (College of American Pathologists) Hair designation and the certification to ISO / IEC 17025 standards.
