Hair assessments are now recognized as an effective method for detecting drug and alcohol usage. Hair retains a prolonged history of substances by embedding biomarkers within the fibers of the hair strand as it develops. When sampled close to the scalp, hair can reveal drug and alcohol presence for up to a 3-month period. Its collection is straightforward, difficult to alter, and convenient to transport.
A sample of 1.5 inches comprising approximately 200 hair strands (similar in size to a #2 pencil) near the scalp yields 100mg of hair, serving as the optimal amount for analysis and validation. For EtG, supplementary, and/or screenings exceeding 10 panels, 150mg is advised. We suggest using a jeweler's scale to weigh the specimen. If scalp hair isn't available, an equivalent amount of body hair can be used. When mentioning head hair, we mean scalp hair only. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is processed into a lab's system. This step includes verifying the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any data entry that isn't covered by an electronic chain of custody.
Screening is a preliminary assessment for drug substances. While Screening is an economical method to dismiss drug presence in most samples, any positive findings must be confirmed for legal acceptability. Samples showing presumptive positives in Screening need a follow-up confirmation.
For samples deemed presumptively positive during Screening, additional hair is extracted from the original sample for Extraction preparation. This phase extracts drugs from hair at significantly lower concentrations than other techniques (e.g., urine or saliva), highlighting the challenge of hair drug screening.
Positive screening confirmations are executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo necessary washing before confirmation. The laboratory process, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair criteria, and adheres to ISO / IEC 17025 standards.
