Hair testing has emerged as a potent method for identifying drug and alcohol usage. Hair offers an extended history of substance use by capturing biomarkers within the fibers of the growing hair strand. Collected near the scalp, hair can indicate usage for roughly a 3-month period for alcohol and other substances. It’s straightforward to collect, relatively hard to tamper with, and simple to transport.
Gathering a 1.5-inch sample composed of about 200 strands of hair (roughly the size of a #2 pencil) situated closest to the scalp yields 100mg of hair, which is the ideal amount for analysis and confirmation. For EtG, additional tests, and/or panels exceeding 10, 150mg of hair is recommended. It’s advisable to weigh the sample using a jeweler’s scale. Should scalp hair be unavailable, the equivalent amount of body hair may be collected. When discussing head hair, it’s specifically in reference to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The primary four steps in lab processing for a drug test result comprise Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial integration of a sample into a lab's system. This process verifies proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data entry not facilitated by an electronic chain of custody system.
Screening constitutes a preliminary check for substances of abuse. While Screening cost-effectively rules out substance use in most samples, positive screenings require confirmation for court acceptance. Samples presumed positive during Screening necessitate further confirmation.
Upon a presumptive positive result in Screening, additional hair is sourced from the preliminary specimen for Extraction. Here, substances are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), rendering hair drug screening the most challenging method to execute.
Confirmation of any positive screening finding is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleaned as required prior to confirmation. The full lab process from Accessioning to Confirmation is conducted under both the guidance of the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
