Hair examination is increasingly recognized as a potent means for identifying drug and alcohol consumption. Hair captures a long-standing record of alcohol and other substances by embedding biomarkers within the fibers of the hair as it grows. When collected near the scalp, hair can reflect up to an approximate 3-month span of alcohol and drug exposure. Hair collection is straightforward, relatively resistant to tampering, and convenient for shipping.
A sample measuring 1.5 inches, consisting of around 200 hair strands (comparable to the thickness of a #2 pencil) closest to the scalp will yield 100mg of hair, the perfect sample for analysis and confirmation. For EtG, additional assessments, and/or tests exceeding 10 panels, a 150mg sample is advised. We suggest weighing the hair using a jeweler’s scale. If no scalp hair is available, an equivalent amount of body hair can be collected. When discussing head hair, we specifically mean scalp hair. Body hair pertains to other hair varieties (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result includes four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial incorporation of a sample into the laboratory's system. This process confirms the sample was sealed and transmitted correctly, assigns an arbitrary LAN (Laboratory Accessioning Number), and completes any further data entry absent from an electronic chain of custody system.
Screening consists of a preliminary rapid check for drug abuse. Though Screening is an economical means to discard drug use in most samples, a positive indication necessitates confirmation to be court-admissible. Any samples that test presumptively positive in Screening do need subsequent confirmation.
If a sample tests presumptively positive during Screening, additional hair is extracted from the initial sample and prepared for Extraction. Here, drugs are isolated from hair at a significantly lower concentration compared to other techniques (e.g., urine or oral fluid), which makes hair drug screening the most challenging technique to execute.
Confirmation of any positive screening outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positives undergo washing prior to confirmation when necessary. The entire laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
