Hair analysis is recognized as an effective method for identifying the use of drugs and alcohol. Hair retains a historical record of substances by capturing biomarkers in its growing strands. When sourced near the scalp, hair can offer a detection span of up to three months for alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and easy to transport.
A 1.5-inch hair segment of roughly 200 strands (similar in size to a #2 pencil), taken nearest the scalp, provides 100mg of hair, which is optimal for screening and confirmation. For EtG, additions, and/or tests exceeding 10 panels, the recommendation is 150mg of the sample. We advise measuring the specimen using a jeweler's scale. In the absence of scalp hair, an equivalent quantity of body hair can be obtained. Head hair specifically refers to scalp hair, while body hair includes all other types (such as facial and axillary hair).
Process Overview
The process of handling a drug test result in a laboratory involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes an initial entry into the laboratory system. This step ensures the sample's proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and completes any necessary data entry absent in an electronic chain of custody.
Screening is a preliminary, swift assessment for drugs of concern. It's a cost-effective measure to dismiss drug use in most samples; however, a positive result in screening mandates confirmation for legal proceedings. Presumptive positives discovered during Screening necessitate further confirmation.
In instances of presumptive positivity at the Screening phase, additional hair is extracted from the original sample and prepared for Extraction. This stage entails extracting drugs at far lower concentrations from hair compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.
Confirmatory testing of any screening positive occurs through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo washing before confirmation as needed. The complete laboratory procedure from Accessioning through Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.
