Hair analysis has emerged as a potent method for identifying drug and alcohol consumption. Hair retains a prolonged record of substance intake by capturing biomarkers within the strands. When sourced near the scalp, hair can offer up to a 3-month detection period for substances. It is straightforward to collect, relatively tamper-resistant, and simple to transport.
A 1.5-inch section of approximately 200 hair strands (similar in thickness to a #2 pencil) nearest to the scalp yields 100mg, which is optimal for both preliminary and confirmatory analysis. For EtG, add-ons, and/or extensive panels above 10 panels, a 150mg sample is advisable. Utilizing a jeweler’s scale for measurement is recommended. In cases where scalp hair is unobtainable, a comparable amount of body hair is acceptable. “Head hair” specifically pertains to scalp hair, whereas “body hair” encompasses all other types (facial, axillary, etc.).
Process Overview
The drug testing laboratory procedure comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into the lab system, which includes ensuring the sample was sealed and shipped correctly, allocating a unique LAN (Laboratory Accessioning Number), and inputting any further data absent in an electronic chain of custody setup.
Screening acts as a preliminary assessment for drugs. Though cost-efficient for excluding drug use in most samples, a screening positive must be confirmed to be valid in legal settings. Samples suspected to be positive in Screening necessitate a confirmatory test.
For samples presumed positive in Screening, additional hair is extracted from the original specimen for Extraction. Here, drugs are extracted from hair at lower concentrations compared to methods like urine or oral fluid testing, marking hair drug screening as the most complex methodology available.
Confirmation of a positive screen entails GC/MS, GC/MS/MS, or LC/MS/MS analysis. Any samples tentatively positive are washed before confirmation when required. The laboratory procedure from start to finish is audited under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
