The utilization of hair analysis has emerged as an effective means for identifying the consumption of drugs and alcohol. Hair retains a historical record of alcohol and various substances by incorporating biomarkers within the hair shaft as it grows. When gathered near the scalp, hair can yield roughly a 3-month detection period for alcohol and drugs. It is straightforward to collect, relatively resistant to tampering, and conveniently shipped.
A 1.5-inch segment of approximately 200 strands (resembling a #2 pencil) nearest to the scalp offers 100mg of hair, which is the preferred amount for evaluation and confirmation. For tests including EtG, additional screenings, or beyond 10 panels, a collection of 150mg is suggested. Verification of the specimen's weight using a jeweler’s scale is advised. In cases where scalp hair is not available, a comparable amount of body hair can be collected. In reference to head hair, it pertains solely to scalp hair, whereas body hair encompasses every other type (facial, axillary, and others).
Process Overview
The drug test result's laboratory process comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab's system. This step includes confirming the sample's proper sealing and shipment, assigning it a random Laboratory Accessioning Number (LAN), and completing any missing data entry not already provided by an electronic chain of custody system.
Screening consists of an initial abbreviated inspection for drugs of abuse. Though Screening is a cost-effective strategy to eliminate drug use for most samples, a positive screen mandates confirmation to be admissible in legal contexts. Any samples showing presumptive positivity during Screening must undergo further validation.
Should a sample display presumptive positivity during Screening, further hair will be extracted from the original sample for the Extraction stage. Here, drugs are extracted from hair at concentrations significantly lower than those in other methods (e.g. urine or oral fluid), underscoring the complexity of conducting hair drug screening.
The verification of any positive screening outcomes is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity undergo washing before confirmation as needed. The entire lab procedure from Accessioning through Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
