Hair testing is now recognized as an effective method for identifying drug and alcohol consumption. Hair offers a comprehensive timeline of substance usage by capturing biomarkers within the fibers of the hair as it grows. When taken from near the scalp, hair can reveal up to around a 3-month history of alcohol and drug use. Hair is easy to collect, less prone to tampering, and straightforward to transport.
A sample close to 1.5 inches consisting of about 200 strands (roughly the circumference of a #2 pencil) nearest the scalp equates to 100mg, the optimal amount for analysis and validation. For EtG, additional tests, and/or panels exceeding 10 tests, 150mg of hair is advised. We suggest using a jeweler's scale for specimen measurement. If scalp hair isn't available, a similar volume of body hair might be used. When discussing head hair, we mean scalp hair specifically. Body hair denotes all other types (such as facial and axillary hair).
Process Overview
The primary stages in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial inclusion of a sample into a lab’s systems. This covers checking that the sample was sealed and shipped correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data input not covered by an electronic chain of custody protocol.
Screening refers to a preliminary fast evaluation for substances of abuse. While Screening is efficient for dismissing drug use in most cases, a positive initial test must be validated to hold up in legal settings. Samples that show a potential positive during Screening necessitate further confirmation.
For samples showing potential positives in Screening, additional hair is extracted from the original sample and made ready for Extraction. During this phase, drugs are separated from hair at notably lower concentrations than other methods (e.g., urine or oral fluids), illustrating why hair drug screening is the most challenging methodology to execute.
Positive Screening results are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples that are possibly positive undergo washing before confirmation when necessary. The complete laboratory workflow from Accessioning to Confirmation is conducted under the guidelines of both the CAP (College of American Pathologists) Hair category and accreditation to ISO / IEC 17025 standards.
