Hair assessments have gained recognition as an effective method for identifying alcohol and drug consumption. The hair stores long-term records of drugs and alcohol by embedding biomarkers within the fibers of the maturing hair shaft. When gathered near the scalp, hair can offer an approximate 3-month detection period for substances. Hair is straightforward to obtain, relatively challenging to tamper with, and convenient to transport.
A segment of 1.5 inches comprising approximately 200 hair strands (similar in width to a #2 pencil) adjacent to the scalp will yield 100mg of hair, the optimal size for assessment and validation. For EtG, additional tests, and/or panels exceeding 10, 150mg of the sample is advised. Using a jeweler's scale for weighing is recommended. If scalp hair is nonexistent, an equal quantity of body hair is permissible. References to head hair indicate exclusively scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The laboratory's four primary stages in processing a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning concerns the preliminary handling of a sample within a lab's system. Tasks involve confirming the sample's proper sealing and shipment, designating a random LAN (Laboratory Accessioning Number), and finishing any residual data input absent in an electronic chain of custody protocol.
Screening encompasses an initial swift assessment for drug misuse. Though Screening is a budget-friendly method for excluding drug presence in most samples, a verified positive screen is essential for court acceptance. All presumptive positive samples from Screening necessitate secondary authentication.
Should a sample yield a presumptive positive during Screening, extra hair is extracted from the original sample and set for Extraction. Here, drugs are isolated from the hair at significantly lower concentrations compared to other approaches (e.g., urine or oral fluid), underscoring the complexity of hair drug testing.
Confirmation of any affirmative screening results is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptive positive undergo washing before confirmation if necessary. From Accessioning to Confirmation, the entire lab procedure is scrutinized under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.
