Hair testing is recognized as a significant method for identifying drug and alcohol consumption. By embedding biomarkers in the fibers of the growing hair strand, hair offers an extended timeline for alcohol and drug detection. A sample taken near the scalp can reveal up to a 3-month usage history of alcohol and drugs. The collection process for hair is straightforward, with limited opportunity for tampering, and it is easy to transport.
A 1.5-inch segment from around 200 hair strands (approximating the size of a #2 pencil) nearest to the scalp yields 100mg, which is an optimal sample for analysis and validation. For EtG, additional tests, and/or panels exceeding 10, a specimen weight of 150mg is suggested. To ensure accuracy, weigh the sample using a jeweler’s scale. Should scalp hair be unavailable, an equivalent quantity of body hair can be used. Head hair refers exclusively to scalp hair, while body hair includes all other hair categories (facial, axillary, etc.).
Process Overview
The laboratory workflow for drug test results includes four critical stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial incorporation of a sample into the laboratory system, involving verification of proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing pending data entry not covered by an electronic chain of custody system.
Screening consists of an initial rapid evaluation for substances of abuse. Although Screening is economical for eliminating drug use in most samples, to be court-admissible, a confirmation of a positive screen is necessary. Samples that exhibit presumptive positives during Screening must undergo subsequent confirmation.
When a sample tests presumptive positive during Screening, additional hair is extracted from the initial specimen for the Extraction phase. This phase involves extracting drugs from hair at significantly lower concentrations than other methods (e.g., urine or saliva), rendering hair drug screening the most challenging technique to execute.
Confirmation of any positive screening outcome utilizes GC/MS, GC/MS/MS or LC/MS/MS technologies. Prior to confirmation, all presumptive positives are washed as necessary. The complete lab process from Accessioning to Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair designation and aligns with ISO / IEC 17025 accreditation standards.
