Hair drug and alcohol detection using hair testing has emerged as an effective method. By capturing biomarkers within the fibers of growing hair, it offers a prolonged history of substance use. When obtained near the scalp, hair can reveal evidence of drugs and alcohol for up to roughly three months. The collection process is straightforward, tampering is relatively challenging, and transportation is uncomplicated.
To acquire an optimal sample for evaluation, a 1.5-inch portion consisting of around 200 hair strands (approximately a #2 pencil's thickness) adjacent to the scalp is ideal, yielding 100mg of hair. For EtG, additions, and/or comprehensive panels exceeding 10, a 150mg specimen is suggested. Utilizing a jeweler’s scale for measurement is advisable. Should scalp hair be inadequate, an equivalent amount of body hair can be substituted. "Head hair" denotes scalp hair specifically, whereas "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The drug test laboratory process involves four essential steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, samples are entered into the laboratory system. This stage includes confirming proper sealing and delivery of the sample, assigning a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent in an electronic chain of custody system.
Screening serves as an initial rapid assessment for drugs of abuse. While Screening efficiently identifies negative results for most samples, a positive outcome necessitates confirmation for legal admissibility. Any samples flagged as presumptive positives in Screening undergo secondary confirmation.
Should a sample test presumptively positive during Screening, additional hair is extracted from the initial sample and prepared for Extraction. This phase involves extracting drugs from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening a notably challenging technique to execute.
Confirmation for any positive screening outcomes is conducted using GC/MS, GC/MS/MS, or LC/MS/MS technologies. Presumptive positive samples are washed as required prior to confirmation. The comprehensive laboratory process, from Accessioning through Confirmation, is scrutinized under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
