Hair analysis is recognized as an effective means for identifying substance and alcohol consumption. Hair captures a prolonged history of substances by embedding biomarkers into the fibers of the developing hair strand. When taken near the scalp, hair can offer an approximately 3-month detection period for substances and alcohol use. Hair collection is straightforward, relatively hard to tamper with, and simple to transport.
A 1.5-inch section comprising around 200 hair strands (roughly the width of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the ideal sample size for testing and verification. For EtG, add-ons, and/or assessments exceeding 10 panels, a 150mg sample is suggested. Usage of a jeweler’s scale for weighing the sample is advisable. In cases where scalp hair is unavailable, an equivalent quantity of body hair is acceptable. By head hair, we specifically mean scalp hair. Body hair refers to other types like facial or axillary hair.
Process Overview
There are four primary phases in the lab analysis of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary sample processing into the lab’s system. This phase includes checking that the sample was correctly sealed and transported, issuing a random LAN (Laboratory Accessioning Number), and completing any other data entry tasks not covered by an electronic chain of custody system.
Screening consists of an initial rapid assessment for substance misuse. Though Screening offers a cost-efficient method to rule out usage in most samples, a positive result requires confirmation to hold up in court. Any samples showing presumptive positive results in Screening necessitate an additional confirmation stage.
Should a sample appear presumptively positive in the Screening phase, additional hair is removed from the original sample and prepped for Extraction. At this juncture, substances are extracted from hair at much lower concentrations compared to other approaches (e.g., urine or oral fluid), underscoring the complexity of performing hair drug screening.
The Confirmation of any positive Screening findings occurs through GC/MS, GC/MS/MS, or LC/MS/MS procedures. All samples indicating presumptive positivity are cleaned prior to Confirmation as required. Both the entire laboratory procedure from Accessioning through Confirmation adheres to the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 accreditation standards.
