Hair testing is recognized as an effective instrument for identifying usage of drugs and alcohol. Hair captures biomarkers within its fibers, presenting a long-term profile of alcohol and drug use. When obtained near the scalp, hair can offer approximately a 3-month detection timeline for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A sample of 1.5 inches with roughly 200 strands (around the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is ideal for analysis and validation. For EtG, additional components, and/or assessments surpassing 10 panels, 150mg is advisable. It's suggested to weigh the sample using a jeweler’s scale. Should scalp hair be insufficient, an equivalent amount of body hair can be used. "Head hair" specifically refers to scalp hair only. "Body hair" encompasses all other forms (facial, axillary, etc.).
Process Overview
Processing a drug test result in the lab involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning manages the initial entry of a sample into the lab system. This entails confirming the sample’s seal and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.
Screening performs an initial rapid evaluation for drug presence. While efficient in ruling out drug use in most samples, a positive screen must be verified for court acceptance. Samples presumptively positive in Screening need further confirmation.
If a sample tests presumptively positive during Screening, more hair from the initial sample is extracted and processed for Extraction. Here, drugs are extracted from hair at much lower concentrations than other methods (such as urine or oral fluid), making hair drug screening the most complex method to execute.
Confirmation of any positive screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity are washed as necessary before confirmation. The full lab process from Accessioning to Confirmation undergoes review by both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
