The utilization of hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair encapsulates a prolonged record of such use by locking biomarkers within the fibers of the burgeoning hair strand. When sourced near the scalp, hair can reveal substance use for up to about three months, demonstrating its effectiveness in detection. The collection process for hair is straightforward, poses challenges for tampering, and is convenient for shipping.
A sample measuring 1.5 inches, comprising roughly 200 hair strands (equivalent to the diameter of a #2 pencil) nearest to the scalp, provides 100mg of hair, which is optimal for conducting screenings and confirming results. For EtG, additional tests, and/or analyses exceeding 10 panels, it is advisable to use 150mg of the sample. Utilizing a jeweler's scale to weigh the specimen is recommended. Should scalp hair be unavailable, gathering an equivalent amount of body hair is an option. When discussing head hair, we specifically refer to scalp hair. Conversely, body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The key stages in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary handling of a sample within a lab's framework. This step ensures that the sample was properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data entry not included in an electronic chain of custody system.
Screening involves an initial rapid assessment for drugs of misuse. Although Screening provides a cost-efficient means to exclude drug usage for most samples, a positive result requires Confirmation to be valid for legal proceedings. Samples with a presumptive positive result from Screening necessitate additional confirmation.
If a sample returns a presumptive positive during Screening, further hair is extracted from the initial sample and prepared for Extraction. In this phase, drugs are isolated from hair at a significantly reduced concentration compared to other methods (e.g., urine or oral fluid), emphasizing the complexity of hair drug screening.
Confirmation of any positive screening is achieved via methods like GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positivity are cleansed prior to Confirmation when necessary. The comprehensive laboratory process, from Accessioning to Confirmation, is examined under the CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.
