With its emergence, hair testing is perceived as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of substances by enclosing biomarkers within its fibers. When sourced near the scalp, it offers about a 3-month detection period for substances. The collection of hair is straightforward, somewhat resistant to tampering, and convenient to transport.
A sample measuring 1.5 inches, comprising roughly 200 hair strands (similar to a #2 pencil in thickness) nearest to the scalp delivers 100mg of hair—ideal for both screening and confirming. For testing EtG, additional assessments, and/or more than 10 panels, 150mg of hair is advisable. The sample should be weighed using a jeweler’s scale. Should scalp hair be lacking, an equal quantity of body hair can be used. References to head hair pertain strictly to scalp hair, while body hair includes all other forms (facial, axillary, etc.).
Process Overview
The drug test laboratory processing encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab’s system, ensuring proper sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing supplemental data entry not managed by an electronic chain of custody system.
Screening provides an initial swift evaluation for substances. While Screening serves as an economical way to dismiss drug use in most samples, a positive result mandates confirmation for legal acceptability. Samples with a presumptive positive in Screening require further confirmation.
In the event a sample shows a presumptive positive in Screening, additional hair is extracted from the original sample for preparation in the Extraction phase. Here, drugs are withdrawn from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), making hair drug testing notably challenging.
Confirmation of a positive screening outcome is performed with GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing where necessary before confirmation during this step. The complete lab process, from Accessioning to Confirmation, is scrutinized per the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
