Hair assessments have emerged as an effective method for identifying drug and alcohol consumption. By encapsulating biomarkers within the strands' fibers, hair offers an extended timeline of substance usage. Collected near the scalp, hair samples can track substance consumption for approximately three months. The process of obtaining hair samples is straightforward, challenging to tamper with, and convenient for shipping.
A sample measuring 1.5 inches, comprising roughly 200 strands (equivalent to a #2 pencil), yields 100mg of hair—ideal for both initial tests and confirmations. For EtG, additional requirements, and extensive tests exceeding ten panels, it's advisable to collect 150mg. Using a jeweler’s scale for precise weighing is suggested. If scalp hair is inaccessible, a corresponding quantity of body hair can be substituted. Head hair specifically refers to scalp hair, while body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The laboratory analysis of drug test results encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the preliminary processing of a sample within the laboratory's system. This stage ensures proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry absent from an electronic chain of custody system.
Screening offers an initial rapid assessment for substances of abuse. While cost-effective for excluding drug presence in most samples, a preliminary positive requires confirmation for legal admissibility. Samples indicating a presumptive positive during Screening demand subsequent confirmation.
During Extraction, more hair is drawn from the original sample if a presumptive positive emerges in Screening. This stage extracts substances from hair at much lower concentrations than other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug assessments.
Confirmation of any positive screening outcome employs GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Prior to confirmation, all presumptive positive samples undergo requisite washing. The comprehensive laboratory procedure from Accessioning to Confirmation is examined both under the CAP (College of American Pathologists) Hair designation and the accreditation aligned with ISO / IEC 17025 standards.
