Hair examination has emerged as an effective mechanism for identifying drug and alcohol consumption. Hair captures a prolonged history of alcohol and substances by embedding biomarkers within the strands. When collected from near the scalp, hair can offer a detection span of up to around 90 days for alcohol and drugs. Hair is straightforward to gather, somewhat resistant to tampering, and convenient to transport.
A segment of 1.5 inches consisting of roughly 200 hair strands (comparable to a #2 pencil) closest to the scalp provides 100mg, the perfect sample for initial screening and further confirmation. For EtG, additions, and assessments exceeding 10 panels, a 150mg sample is advised. We suggest measuring the sample on a jeweler’s scale. If scalp hair isn't available, a comparable quantity of body hair can be collected. When discussing head hair, it strictly refers to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The key procedures involved in laboratory drug test processing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary handling of a sample into the laboratory's infrastructure. This includes ensuring the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any data entry missing from an electronic chain of custody system.
Screening represents an initial rapid probe for illicit substances. Although Screening is an economical approach to exclude drug use in the bulk of samples, a positive indication necessitates confirmation for court acceptance. Any samples with presumptively positive results in Screening demand a subsequent confirmation.
If a sample is presumptive in the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. At this stage, drugs are extracted from hair at a notably lower concentration than in other methods (e.g., urine or oral fluids), underscoring why hair drug testing is among the most challenging methods.
Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation when needed. The entire laboratory process from Accessioning to Confirmation undergoes evaluation under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.
