Hair testing is increasingly recognized as an effective approach for detecting drug and alcohol use. Hair captures a comprehensive history of alcohol and other substances by binding biomarkers within the growing hair strand. When obtained close to the scalp, hair offers a detection timeframe of up to roughly 3 months for alcohol and other substances. It is straightforward to collect, relatively challenging to tamper with, and easy to transport.
A sample measuring 1.5 inches comprising around 200 hairs (comparable to a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal amount for screening and confirmation. For EtG, add-ons, and tests beyond 10 panels, it is suggested to gather 150mg of the sample. Utilizing a jeweler’s scale to weigh the sample is advisable. In cases where scalp hair is not available, an equal quantity of body hair may be utilized. The term head hair pertains solely to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The primary steps in processing a drug test in the laboratory are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves integrating the sample into the laboratory’s system, ensuring proper sealing and shipping, assigning a random Laboratory Accessioning Number (LAN), and inputting any additional data not provided by an electronic chain of custody system.
During Screening, an initial rapid check for drugs of abuse is conducted. While Screening is a cost-effective method to rule out drug use in most samples, a positive result requires confirmation for legal admissibility. Samples with presumptive positive results during Screening need a secondary confirmation.
In the event of a presumptive positive in the Screening phase, additional hair is extracted from the original sample for the Extraction phase. This phase involves extracting drugs from hair at a much lower concentration than methods like urine or oral fluid, making hair drug screening the most demanding methodology to perform.
Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed before confirmation as needed. The complete laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
