Hair analysis has gained recognition as an effective method to uncover drug and alcohol consumption. Hair offers a historical account of substance use through the retention of biomarkers within the hair strands as they grow. If collected near the scalp, hair can extend a detection range for alcohol and drugs up to roughly 90 days. Hair collection is straightforward, challenging to tamper with, and easy to transport.
A 1.5-inch portion comprising roughly 200 hair strands (equivalent to the thickness of a #2 pencil) near the scalp yields 100mg of hair, the perfect amount for screening and validation. For EtG, add-ons, or analyses exceeding 10 panels, 150mg of the sample is advisable. Using a jeweler's scale is recommended for precise specimen weighing. In cases where scalp hair isn't accessible, a comparative quantity of body hair can be gathered. References to head hair specifically mean scalp hair, while body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The laboratory drug test procedure encompasses four critical steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial sample entry into the lab's system, verifying proper sealing and shipment, assigning a LAN (Laboratory Accessioning Number), and completing supplementary data entry absent from an electronic chain of custody setup.
Screening offers an initial swift evaluation for drug presence. While cost-effective, any positive findings here must undergo confirmation for legal admissibility. All presumptive positive results from Screening necessitate secondary validation.
If Screening hints at a positive result, more hair is sourced from the original sample and readied for Extraction. This phase involves isolating drugs from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), marking hair drug screening as a particularly intricate process.
Positive screens are confirmed using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are adequately cleansed before confirmation as required. The entire lab process, from Accessioning to Confirmation, falls under review by both the CAP (College of American Pathologists) Hair program and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although often termed as "hair follicle tests", the analysis pertains to the hair strand, not the follicle beneath the scalp.
