Hair analysis is regarded as an effective means for identifying drug and alcohol consumption. By capturing biomarkers within the strands, hair offers an extensive history of substance use. When sample collection occurs close to the scalp, hair allows for up to a 3-month timeframe for detecting alcohol and drugs. The collection process is straightforward, with minimal risk of tampering, and the samples are convenient to transport.
A specimen of 1.5 inches, consisting of roughly 200 hair strands (similar in size to a #2 pencil) from the scalp area, provides 100mg, which is ideal for both screening and confirmation. For assessments like EtG and tests exceeding 10 panels, a 150mg sample is advisable. It's best to use a jeweler’s scale for accurate specimen weight. Should scalp hair be unavailable, an equivalent amount of body hair is acceptable. The term head hair exclusively references scalp hair, while body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory handling of a drug test follows four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning references the initial incorporation of a specimen into a lab’s system, ensuring the sample’s seal and shipment were intact, assigning a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry omitted by an electronic custody system.
Screening represents a preliminary evaluation for drugs. Although cost-efficient for ruling out drug presence in many specimens, a positive screening necessitates confirmation for legal acceptability. Specimens showing presumptive positive results in Screening require further confirmation.
A presumptive positive result in screening demands additional hair from the initial sample for Extraction. During Extraction, drugs are isolated from hair at a notably lower concentration than other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.
A confirmed positive screening is verified using GC/MS, GC/MS/MS or LC/MS/MS. Necessary samples are cleaned prior to confirmation. Every step from Accessioning to Confirmation undergoes scrutiny following both the CAP (College of American Pathologists) Hair guidelines and the ISO / IEC 17025 accreditation standards.
