Hair assessments are increasingly acknowledged as a robust method for identifying substance and alcohol consumption. By embedding biomarkers within the strands, hair offers an extended history of drug use. When gathered near the scalp, the hair can provide a detection span of up to three months for substances and alcohol. The collection process for hair is straightforward, challenging to tamper with, and easy to dispatch.
A hair sample measuring 1.5 inches in length, consisting of approximately 200 strands (around the thickness of a #2 pencil) from the closest scalp area, yields 100mg—the optimal amount for analysis and verification. For EtG additions or assessments beyond ten panels, 150mg of hair is advisable. We suggest using a jeweler’s scale for specimen measurement. If scalp hair cannot be accessed, a similar quantity of body hair can be gathered. The term head hair specifically refers to scalp hair. Body hair includes all other kinds, such as facial and axillary hair.
Process Overview
The laboratory processing of a drug test result follows four fundamental steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage of integrating a sample into a laboratory's system, involving verification of sample sealing and proper shipment, assignment of a random LAN (Laboratory Accessioning Number), and completion of any additional data entry not covered by an electronic chain of custody system.
Screening is a preliminary examination for substance use. Although Screening is economical for excluding drug use in most samples, a positive Screening result requires verification to be valid for court proceedings. All samples that are preliminarily positive in Screening necessitate an additional confirmation step.
Upon a positive outcome in Screening, additional hair from the original sample is used for Extraction. This phase involves extracting drugs from hair at a concentration much lower than in other methods like urine or oral fluids, underscoring the complexity of hair drug screening as a methodology.
GC/MS, GC/MS/MS or LC/MS/MS are utilized for confirming any positive Screening results. Before confirmation, any samples with presumptive positives undergo necessary washing. The entire process from Accessioning to Confirmation is evaluated under the auspices of both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
