Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair retains biomarkers within its fibers, offering a long-term record of substance use. Collected near the scalp, hair offers a detection potential for substances for up to about three months. It's easy to collect, challenging to tamper with, and simple to transport.
A 1.5-inch segment of roughly 200 hair strands (similar in thickness to a #2 pencil) nearest to the scalp produces 100mg of hair, which is optimal for testing and verification. For EtG, complimentary tests, and assessments beyond 10 panels, a collection of 150mg is advised. It's beneficial to assess the sample weight using a jeweler's scale. If scalp hair isn't available, a comparable amount of body hair might be taken. Head hair refers solely to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The core processes in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning denotes the initial intake of a sample into the lab's database, ensuring the sample was properly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and performing any necessary data entry not covered by an electronic custody system.
Screening is a preliminary rapid assessment for substance misuse. While it's a budget-friendly approach to eliminating drug usage from the majority of samples, any sample with a positive result requires confirmation to be legally valid. Samples with presumptive positive results in Screening need further verification.
Upon a presumptive positive result in the Screening phase, more hair is extracted from the initial sample for the Extraction process. Drugs are then isolated from hair at much lower concentrations than with other methods (e.g., urine or saliva), emphasizing the complexity of hair drug analysis.
Verification of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo cleansing prior to confirmation as needed. The entire lab process from Accessioning to Confirmation occurs under the oversight of both the CAP (College of American Pathologists) Hair designation and the image ISO/IEC 17025 standards.
