Hair analysis has evolved into a robust method for identifying drug and alcohol consumption. Hair strands capture and retain biomarkers within their fibers, offering a prolonged history of substance use. When the hair is harvested near the scalp, it can provide an approximate 3-month detection span for both alcohol and drugs. It's straightforward to gather, relatively resistant to tampering, and convenient to transport.
A segment measuring 1.5 inches, composed of roughly 200 hair strands (comparable to a #2 pencil's width) near the scalp, yields 100mg of hair, which is an optimal sample for both screening and confirmatory purposes. For EtG, additional tests, or those exceeding 10 panels, a 150mg specimen is advised. It's suggested to weigh the hair using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can be taken. References to head hair pertain exclusively to scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The lab processing of a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes integrating a sample into a lab's system initially. This step involves confirming that the sample is correctly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and finishing any extra data tasks absent from an electronic chain of custody system.
Screening consists of a preliminary rapid check for substances of abuse. Although Screening is a cost-efficient means to dismiss drug usage for most samples, a positive outcome requires confirmation for legal admissibility. Samples that are presumptively positive in Screening necessitate secondary validation.
Presumptive positives in the Screening phase require more hair from the initial collection for preparation in the Extraction phase. During this phase, drug compounds are extracted from hair at much lower concentrations than other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug analysis compared to other testing methodologies.
In the Confirmation phase, any positive screening outcomes are verified using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are washed pre-confirmation if necessary. The comprehensive lab procedure from Accessioning to Confirmation adheres to standards from both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
