Hair analysis is recognized as an effective method for identifying drug and alcohol use. As hair grows, it captures biomarkers within its strands, offering an extended timeline of substance consumption. When hair is sampled near the scalp, it can reveal drug or alcohol use for up to three months. Collecting hair is straightforward, challenging to tamper with, and convenient for shipping.
A sample length of 1.5 inches, consisting of roughly 200 hair strands (approximately equivalent to the thickness of a #2 pencil), yields 100mg, which is the optimal amount for testing and validation. For tests including EtG, additional screenings, or more than 10-panel analyses, 150mg of hair is advisable. Using a jeweler's scale to weigh the sample is recommended. If scalp hair isn't accessible, an equal portion of body hair serves as an alternative. "Head hair" refers solely to scalp hair, whereas "body hair" encompasses all other types such as facial or axillary hair.
Process Overview
The drug testing process in a laboratory involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial stage where samples are processed within the lab's system. This phase ensures samples are properly sealed and sent, assigns a unique LAN (Laboratory Accessioning Number), and completes missing data entries not available through electronic chain of custody systems.
Screening serves as a preliminary assessment for substance abuse. It's an economical method to exclude drug usage in most samples, yet positive findings require confirmation for court acceptability. Samples that test positive during the Screening stage necessitate further confirmation.
For samples testing positive in Screening, additional hair is extracted from the initial sample for use in Extraction. This phase involves isolating drugs from hair at much lower concentrations than other testing methods like urine or oral fluid, making hair drug screening particularly challenging.
Confirmation of positive screening results utilizes GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptively positive samples are washed before undergoing confirmation if necessary. The entire process, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
