Hair analysis has become recognized as a significant means for identifying drug and alcohol consumption. Hair retains a prolonged timeline of alcohol and other substances by embedding biomarkers within the strands of the developing hair. When acquired near the scalp, hair can yield up to a roughly 3-month detection timeframe for alcohol and other substances. Hair is straightforward to obtain, relatively secure against tampering, and simple to transport.
A 1.5-inch segment encompassing around 200 hair strands (roughly matching the girth of a #2 pencil) nearest to the scalp will provide 100mg of hair, which is the optimal sample for assessment and verification. For EtG, supplementary tests, and/or evaluations over 10 panels, 150mg of the sample is advised. We suggest measuring the sample on a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair may be gathered. When mentioning head hair, we specifically mean scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The key stages in the laboratory processing of a drug test result comprise Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a specimen into a laboratory’s system. This encompasses validating that the specimen was sealed and dispatched correctly, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any supplementary data input not provided by an electronic chain of custody mechanism.
Screening comprises a preliminary swift assessment for substances of abuse. Although Screening is a cost-effective approach to eliminate drug usage in most specimens, a positive screen must be substantiated to be permissible in legal proceedings. Any specimens that are presumptively positive during Screening necessitate a secondary confirmation.
If a specimen is presumptively positive at the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. During this phase, substances are extracted from hair at a substantially lower concentration than in other approaches (e.g., urine or oral fluid), rendering hair drug screening the most challenging technique to execute.
Confirmation of any positive screening outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens are cleansed prior to confirmation as required. The comprehensive laboratory process from Accessioning to Confirmation is appraised under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
