Hair testing is now recognized as a significant method for identifying the use of drugs and alcohol. It offers a comprehensive timeline of alcohol and drug consumption by embedding biomarkers in the fibers of the hair as it grows. By collecting hair near the root, one can achieve up to a 3-month timeframe for alcohol and drug detection. Hair acquisition is straightforward, challenging to tamper with, and convenient for shipping.
A 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil) taken near the scalp will amount to 100mg, which is the optimal quantity for testing and verification. For testing like EtG, add-ons, and panels exceeding 10, 150mg of hair is suggested. Using a jeweler’s scale for weighing the hair sample is advised. If head hair isn't obtainable, a similar quantity of body hair may be used. In mentioning head hair, it specifically pertains to hair from the scalp. Body hair includes other types of hair (facial, axillary, etc.).
Process Overview
The drug testing process in a lab generally follows four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning initiates the process by integrating a sample into the lab's system. This phase ensures the sample is sealed and delivered correctly, assigns a unique LAN (Laboratory Accessioning Number), and completes necessary data entries not covered by an electronic chain of custody system.
Screening performs an initial assessment for commonly abused drugs. Although Screening is an economical method to negate drug use in most samples, any detected positives must be confirmed for legal validity. Samples deemed presumptively positive in the Screening phase need a follow-up confirmation.
For samples flagged as presumptively positive, additional hair from the original sample is used to prepare for Extraction. During Extraction, drug compounds are derived from hair at much lesser rates than other methods (e.g., urine or oral fluid), highlighting the intricate nature of hair drug testing.
GC/MS, GC/MS/MS or LC/MS/MS techniques confirm any positive screening outcomes. Before confirmation, all samples marked presumptively positive are cleaned if necessary. The complete lab sequence, from Accessioning to Confirmation, adheres to CAP (College of American Pathologists) Hair protocols and meets ISO / IEC 17025 accreditation standards.
