Hair analysis has emerged as a significant technique for identifying the presence of drugs and alcohol. Hair captures a long-term record of substance use by incorporating biomarkers within the fibers as the hair grows. When obtained near the scalp, hair offers roughly a 3-month period for detecting various substances, including alcohol. Collecting hair is straightforward, challenging to tamper with, and easy to transport.
By securing a 1.5-inch segment of approximately 200 hair strands (roughly equivalent to the diameter of a #2 pencil) close to the scalp, you procure 100mg of hair, which is the preferred specimen size for initial and confirmatory testing. For procedures like EtG, additional analyses, or when testing exceeds 10 panels, 150mg of the sample is advised. It is beneficial to use a jeweler's scale for weighing. If head hair cannot be sourced, an equivalent mass of body hair is acceptable. "Head hair" strictly refers to scalp hair. "Body hair" encompasses all other types (such as facial and axillary hair).
Process Overview
There are four fundamental phases in the testing of a drug sample at a laboratory: Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of entering a sample into the laboratory's tracking system. This stage ensures that the sample is properly sealed and transported, allocates a random LAN (Laboratory Accessioning Number), and handles necessary data entry absent in an electronic chain of custody framework.
Screening functions as a preliminary assessment for illicit substances. It is a cost-efficient method to exclude drug use for most samples, yet any positive result in this phase must undergo Confirmation for legal admissibility. Samples that yield a presumptive positive in Screening necessitate secondary verification.
When Screening suggests a presumptive positive, additional hair is extracted from the primary specimen and readied for Extraction. At this step, drugs are isolated from hair at a considerably lower concentration than other methods (such as urine or saliva), underscoring hair testing as a complex procedure.
A confirmatory test for any positive screening results employs methods like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples are cleaned before confirmation as required. The complete lab procedure, from Accessioning to Confirmation, complies with both the CAP (College of American Pathologists) Hair certification and ISO / IEC 17025 accreditation standards.
