Hair analysis has gained recognition as a potent resource for identifying drug and alcohol consumption. Hair offers an extended timeline of drug and alcohol history by embedding biomarkers within the fibers of the growing strand. When gathered near the scalp, it can reveal a detection span of up to 3 months for drugs and alcohol. Hair collection is straightforward, relatively tamper-resistant, and conveniently packed for shipping.
A 1.5-inch segment of around 200 strands (comparable to a #2 pencil) taken closest to the scalp produces 100mg, the optimal amount for both screening and confirmation tests. For EtG, additional tests, and those beyond 10 panels, a 150mg specimen is advised. Utilizing a jeweler's scale is suggested for weighing. If scalp hair is not available, a comparable portion of body hair can be collected. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other hair types (e.g., facial, axillary).
Process Overview
The lab processing for drug test results involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial phase where a sample is incorporated into a lab's system. This includes verifying the seal and shipment integrity, assigning a LAN (Laboratory Accessioning Number), and completing any further data entry absent from an electronic chain of custody.
Screening is a preliminary rapid assessment for drug presence. Though Screening is cost-effective for excluding drug use in most samples, a positive finding requires confirmation for court admissibility. Presumptive positive samples in Screening demand further verification.
For samples flagged presumptively positive in Screening, additional hair is extracted from the original sample for Extraction. Here, drugs are isolated at much lower concentrations than other methods (e.g., urine, oral fluid), highlighting the difficulty in conducting hair drug tests.
Confirmation for any positive screening proceeds via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation, as needed. The complete lab process from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Despite often being termed "hair follicle tests," the exam actually analyzes the hair strand rather than the follicle beneath the scalp.
