Hair assessments are now recognized as a significant means for identifying substance and alcohol use. Hair encapsulates a prolonged record of alcohol and other substances by capturing biomarkers within the strands of hair as they grow. When procured near the scalp, hair offers nearly a 3-month period for identifying alcohol and drugs. Collecting hair is straightforward, comparatively resistant to tampering, and convenient to transport.
A lock of hair measuring 1.5 inches, containing around 200 strands (about the thickness of a #2 pencil) nearest to the scalp, yields 100mg of hair, the optimal quantity for both checking and confirming. For EtG, additional examinations, and/or assessments exceeding ten panels, it is advisable to have 150mg of the sample. It's recommended to measure the sample using a jeweler’s balance. If head hair is not accessible, a similar volume of body hair may be obtained. When discussing head hair, it pertains solely to scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning relates to the initial incorporation of a sample into a laboratory’s framework. This process ensures the sample was appropriately sealed and shipped, assigns an arbitrary LAN (Laboratory Accessioning Number), and executes supplementary data entry not available through an electronic chain of custody system.
Screening serves as an initial rapid assessment to detect illicit drug use. Although Screening is an economical tactic for eliminating drug usage for most samples, a confirmed result is needed for admissibility in a court setting. Any presumptively positive Screening samples indeed require subsequent confirmation.
Should a sample show presumptively positive in the Screening stage, additional hair is extracted from the original specimen and prepared for Extraction. At this point, drugs are extracted at notably lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening among the most challenging methodologies to conduct.
Confirmation for any positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples with a presumptive positive need to be cleansed before confirmation when necessary. From Accessioning to Confirmation, the entire laboratory procedure is scrutinized under both the CAP (College of American Pathologists) Hair category and the accreditation to ISO / IEC 17025 standards.
