Hair analysis is now recognized as an effective means for identifying drug and alcohol consumption. Hair captures long-term indicators of substances by embedding them in the hair's structure as it grows. When cut near the scalp, hair can reveal drug and alcohol intake history for up to a 90-day period. It is straightforward to collect, challenging to tamper with, and convenient for transport.
Collecting a 1.5-inch section of about 200 hairs (similar to the width of a #2 pencil) close to the scalp will yield 100mg, which is sufficient for testing and verification. For EtG, additional analyses, and tests exceeding 10 panels, 150mg of hair is advised. It is suggested to measure the sample using a jeweler’s scale. If scalp hair is not an option, a similar quantity of body hair may be used. By head hair, we only mean scalp hair. Body hair includes other types (facial, axillary, etc.).
Process Overview
The primary steps in lab processing for a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning handles the initial integration of a sample into a lab's system. This process includes confirming the sample's proper seal and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not available from an electronic chain of custody system.
Screening is a preliminary evaluation for substances of abuse. Although Screening is an economical approach to exclude drug use in most samples, findings must be verified to be legally valid. Samples that test presumptively positive in the Screening phase require a follow-up confirmation.
If a sample tests positive during Screening, additional hair is taken for Extraction. Here, drugs are isolated from the hair at a lower concentration than with other methods (e.g., urine or saliva), necessitating that hair drug testing is the most challenging method to execute.
Confirmation of any positive result from screening is achieved using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples are cleansed before final evaluation if necessary. The end-to-end lab process from Accessioning through Confirmation is audited as per both CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 certification.
