Hair analysis has garnered a reputation as a highly effective tool for identifying drug and alcohol consumption. Hair offers an extended historical perspective on alcohol and drug use by embedding biomarkers within the strands of emerging hair. When procured near the root, hair can offer a detection duration of up to roughly three months for alcohol and drugs. The collection of hair is straightforward, relatively difficult to tamper with, and convenient to transport.
A sample measuring 1.5 inches in length with around 200 hair strands (resembling the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal amount for testing and verification. For EtG, additional tests, and/or analyses exceeding 10 panels, 150mg of the sample is advisable. Utilizing a jeweler’s scale for specimen measurement is recommended. If scalp hair is absent, a comparable amount of body hair can be gathered. When referencing head hair, it specifically pertains to scalp hair. Body hair encompasses all other varieties (face, underarm, etc.).
Procedure Summary
The principal phases in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the preliminary intake of a sample into a lab’s database. This phase ensures the sample was properly sealed and sent, assigns a unique LAN (Laboratory Accessioning Number), and supplements any additional data not entered by an electronic chain of custody system.
Screening pertains to an initial rapid assessment for substance abuse. Screening serves as a cost-effective means to exclude drug use for most samples, yet a positive screen necessitates verification to be admissible in legal actions. Samples deemed presumptively positive in Screening require an additional validation.
When a sample tests presumptively positive during the Screening phase, additional hair is extracted from the original sample and set up for Extraction. In this phase, drugs are separated from hair at a considerably lower concentration compared to other methods (e.g., urine or oral fluid), hence hair drug screening is the most intricate methodology to execute.
Verification of any positive screening outcome is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positives undergo washing prior to confirmation as needed. The complete lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 criteria.
