The utilization of hair testing has become recognized as an effective instrument in identifying drug and alcohol consumption. Hair retains a prolonged history of alcohol and drugs by embedding biomarkers within its fibers as it grows. When hair is obtained near the scalp, it can yield an approximately 3-month detection period for alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and easily shipped.
A 1.5-inch section comprising roughly 200 hair strands (about pencil-width size) nearest to the scalp will result in 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, or panels exceeding 10, 150mg of the sample is advised. Utilizing a jeweler’s scale for specimen weighing is recommended. If scalp hair is absent, an equal volume of body hair may be used. Head hair refers exclusively to scalp hair, while body hair includes all other types, such as facial or axillary hair.
Process Overview
The drug test laboratory process is comprised of four core stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial processing into the laboratory's system, ensuring proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing additional data entries beyond what an electronic chain of custody system provides.
Screening is a preliminary rapid check for drug presence. While cost-efficient for excluding drug use in most samples, a positive screen demands confirmation to be court-admissible. Samples flagged as presumptively positive in Screening necessitate secondary confirmation.
For samples marked presumptively positive in Screening, further hair is extracted from the initial batch and prepared for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), thus making hair drug screening a challenging methodology to implement.
GC/MS, GC/MS/MS, or LC/MS/MS techniques conduct the Confirmation of any positive screening outcomes. Presumptive positive samples undergo washing before confirmation as necessary. The complete laboratory procedure, from Accessioning to Confirmation, undergoes scrutiny under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
