Testing hair has emerged as a formidable approach for uncovering drug and alcohol consumption. The strands serve as a recorded chronicle of drug activity, capturing biomarkers within the fiber structure of hair as it grows. When collected near the scalp, these strands can exhibit evidence of substance use within a period reaching up to three months. Hair is straightforward to gather, moderately tough to tamper with, and conveniently shipped.
A section of hair measuring 1.5 inches in length and comprising approximately 200 strands (comparable in size to a #2 pencil) near the scalp yields 100mg, an optimal amount for both screening and validation. For tests involving EtG, additional panels, or those exceeding 10 panels, a quantity of 150mg is preferred. It is recommended to measure the sample using a jeweler’s scale. Should scalp hair be unavailable, a similar quantity of body hair may serve as an alternative. By scalp hair, we refer explicitly to head hair. Body hair encompasses all other types, including facial and axillary hair.
Process Overview
The process includes four key stages in processing a drug test result at the laboratory: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial processing into the laboratory system. This process involves ensuring that the sample was suitably sealed and transported, assigning it a unique LAN (Laboratory Accessioning Number), and recording any supplemental data not captured by an electronic chain of custody system.
Screening entails an initial rapid evaluation for substances of abuse. Though it offers a cost-effective means to eliminate drug usage in most samples, positive results in this phase require subsequent validation to be eligible for legal proceedings. Samples yielding presumptive positive outcomes in Screening mandate further confirmation.
When a sample appears presumptively positive during Screening, additional hair is extracted from the initial sample and readied for Extraction. This phase involves extracting drugs from hair at lesser concentrations than in other methods (e.g., urine or saliva), rendering hair drug screening the most challenging method to execute.
The Confirmation phase for any positive screening outcomes is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to Confirmation, all samples deemed presumptively positive receive a washing process as required. The complete laboratory process, spanning from Accessioning to Confirmation, undergoes evaluation under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.
