The analysis of hair has emerged as a potent method for identifying the consumption of drugs and alcohol. Hair serves as a long-term archive of drug and alcohol use by capturing biomarkers in its strands as they grow. When obtained close to the scalp, hair offers a detection period of up to roughly three months for alcohol and drugs. Hair is straightforward to gather, relatively tough to alter, and uncomplicated to transport.
A sample measuring 1.5 inches with around 200 strands of hair (comparable in volume to a #2 pencil) near the scalp equates to 100mg of hair, an optimal amount for both screening and verification. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advisable. Using a jeweler's scale, weighing the specimen is suggested. Should scalp hair not be an option, a similar quantity of body hair is acceptable. References to head hair denote only scalp hair, whereas body hair encompasses all other varieties (facial, axillary, and so forth).
Process Overview
The laboratory processing of a drug test result includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the sample's initial integration into the lab's system. This step ensures the sample's proper sealing and shipping, allocates a random LAN (Laboratory Accessioning Number), and completes any leftover data entry absent from an electronic chain of custody system.
Screening conducts an initial swift evaluation for substance abuse. While Screening is a cost-efficient method to verify the absence of drug use in most samples, positive screenings must be confirmed for legal validity. Samples presumptively positive during Screening necessitate a follow-up confirmation.
Should a sample appear presumptively positive in the Screening phase, additional hair from the original sample is used for Extraction. This phase extracts drugs from hair at much diminished concentrations compared to other techniques (e.g., urine or oral fluid), showcasing why hair drug testing is among the most challenging to perform.
Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples go through washing before confirmation if needed. The comprehensive lab process from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
