Hair analysis has emerged as an effective method for tracing drug and alcohol consumption. Hair retains a prolonged record of substance intake, capturing biomarkers within its growing strands. When sampled close to the scalp, hair can offer a detection period of up to about three months for both alcohol and drugs. The collection of hair is straightforward, relatively tamper-resistant, and convenient for transport.
A sample measuring 1.5 inches, consisting of roughly 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp yields 100mg of hair, which is ideal for both screening and confirmation. For tests such as EtG, other add-ons, or those exceeding 10 panels, 150mg of hair is advised. It is recommended to weigh the hair on a jeweler’s scale. Should scalp hair be inaccessible, a similar quantity of body hair may be used. "Head hair" specifically denotes scalp hair, while "body hair" encompasses all other hair types (such as facial or axillary).
Process Overview
The four key stages in the laboratory analysis of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial integration of a sample into a laboratory system. This step ensures the sample was properly sealed and shipped, assigns it a unique LAN (Laboratory Accessioning Number), and completes any missing data not captured by an electronic chain of custody system.
Screening involves a preliminary rapid test for drugs of abuse. Although Screening is a cost-efficient approach to exclude drug use for most samples, a confirmed positive result is essential for legal admissibility. Thus, samples with presumptive positive results in Screening must undergo further confirmation.
When a sample is indicative of a positive result during Screening, additional hair is taken from the original sample and prepared for Extraction. In this phase, drug compounds are extracted from hair at significantly lower concentrations than other tests like urine or oral fluid, explaining why hair drug screening is among the most challenging methodologies.
Confirmation of any presumptive positive screening result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Any samples testing positive in Screening are washed prior to confirmation as required. The complete laboratory process, from Accessioning through to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair standards and aligns with ISO/IEC 17025 accreditation.
