Hair analysis has emerged as an invaluable resource in detecting drug and alcohol consumption. Hair can capture a prolonged timeline of substance use by embedding biomarkers in the strands of growing hair. When collected near the scalp, it can offer a window of detection up to roughly three months for substances. Hair collection is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch segment of roughly 200 hair strands (comparable in size to a #2 pencil) nearest the scalp yields 100mg, the optimal quantity for both screening and confirmation. For EtG, additional tests, and tests exceeding ten panels, a specimen of 150mg is advised. Using a jeweler’s scale for specimen weighing is suggested. In cases where scalp hair isn't available, an equivalent amount of body hair can be gathered. "Head hair" specifically refers to scalp hair, while "body hair" pertains to all other types (facial, axillary, etc.).
Process Overview
The four principal stages in lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the initial sample incorporation into a lab's system, ensuring the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data entry absent from an electronic chain of custody system.
Screening administers a preliminary swift check for substances. Despite Screening being cost-efficient for eliminating substance use in the majority of samples, a positive screen requires confirmation for legal admissibility. Any samples testing presumptively positive in Screening necessitate a secondary confirmation.
If a sample presents presumptively positive during Screening, additional hair is extracted from the initial sample for the Extraction phase. Here, substances are extracted from hair at significantly lower concentrations than in other approaches (e.g., urine or oral fluid), establishing hair drug screening as the most complex methodology.
Confirmation of any positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing as needed prior to confirmation. The comprehensive lab process, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
