Hair analysis has emerged as a compelling approach for identifying drug and alcohol consumption. Hair retains a long-standing record of alcohol and drug intake by embedding biomarkers within the fibers of the hair shaft as it grows. Hair collected near the scalp can offer a detection span of up to roughly 3 months for alcohol and drugs. It's straightforward to collect, challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches of roughly 200 hair strands (comparable to a #2 pencil width) nearest to the scalp provides 100mg of hair, the optimal sample for screening and verification. For EtG, supplemental, and/or tests exceeding 10 panels, a 150mg sample is advised. We suggest using a jeweler's scale for specimen measurement. If scalp hair isn’t available, a comparable quantity of body hair can be obtained. References to head hair pertain exclusively to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The primary steps involved in lab processing for a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial sample integration into a lab system. It involves verifying proper sealing and shipping of the sample, assigning an arbitrary LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent in an electronic chain of custody system.
Screening involves an initial rapid assessment for drug misuse. While Screening offers a cost-efficient method to exclude drug use for the majority of samples, a confirmed positive screen is necessary for legal admissibility. Samples that show presumptive positives in Screening mandate secondary confirmation.
If a sample displays presumptive positivity during Screening, additional hair is extracted from the initial sample for Extraction. Here, drugs are isolated from hair at far lower concentrations than in methods like urine or oral fluid, highlighting why hair drug screening is a challenging approach to execute.
Positive screening outcomes undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, any presumptive positive samples are washed if needed. The comprehensive lab process from Accessioning to Confirmation undergoes evaluation under the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.
