Hair testing is now recognized as an effective method for identifying drug and alcohol consumption. Hair serves as a record of prolonged alcohol and substance use, capturing biomarkers within the fibers of the growing strands. When taken near the scalp, hair can reveal a history of use over roughly a 3-month period for alcohol and drugs. Collection is straightforward, resisting tampering, and easy to transport.
A 1.5-inch section comprising around 200 strands (about the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, the prime sample for testing and verification. For EtG, additional tests, and those exceeding 10 panels, it is advisable to have 150mg of hair. Utilizing a jeweler’s scale for measuring the sample is advisable. If scalp hair is not available, an equivalent quantity of body hair can be collected. "Head hair" refers exclusively to scalp hair. "Body hair" pertains to all other types, including facial and axillary hair.
Process Overview
The primary steps in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning accredits the sample into the lab's workflow, confirming the secure sealing and proper shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any data not provided electronically via the chain of custody system.
Screening entails a preliminary assessment for signs of drug use. While it’s a cost-effective method to exclude drug use in the majority of instances, a positive screening requires validation for legal acceptance. All presumptively positive screen results necessitate subsequent verification.
Should a sample signal presumed positivity in the Screening phase, additional hair is extracted from the original sample for the Extraction phase. During this phase, drugs are extracted from the hair at a significantly lower concentration compared to other techniques (such as urine or oral fluid testing), making hair drug screening particularly complex.
Confirmation of a positive screening is conducted using GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples assumed to be positive are washed before confirmation, if necessary. The comprehensive laboratory procedures, from Accessioning to Confirmation, are reviewed under the CAP (College of American Pathologists) Hair designation and conform to ISO / IEC 17025 standards.
