Hair analysis is now recognized as an effective method for detecting the use of drugs and alcohol. Hair captures a historical record of alcohol and other substances by retaining biomarkers within the fibers of the hair as it grows. When clipped closely to the scalp, hair can reveal substance use over an approximate period of three months. Hair collection is straightforward, generally hard to tamper with, and easily transportable.
A strand length of 1.5 inches consisting of approximately 200 hairs (roughly matching the diameter of a #2 pencil) from near the scalp should yield 100mg, which is the perfect amount for initial testing and validation. For EtG, additional testing, or analyses exceeding 10 panels, 150mg of hair is preferred. Measuring the sample using a jeweler's scale is advisable. If head hair cannot be provided, a similar quantity of body hair can be utilized. The term 'head hair' pertains specifically to scalp hair, whereas 'body hair' refers to other types such as facial or underarm hair.
Process Overview
The primary stages in laboratory processing for drug test analysis include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial intake of the sample into a lab's framework. This involves certifying that the sample was correctly sealed and transported, assigning it a unique LAN (Laboratory Accessioning Number), and completing any additional documentation not accessible through a digital chain of custody system.
Screening provides an initial assessment for drug presence. Although Screening is an economical method to eliminate drug use in most instances, a positive finding in Screening must be corroborated to hold legal validity. Any test results indicating potential positivity in Screening necessitate further validation.
Should a test yield a possible positive at the Screening phase, additional hair is procured from the original sample and readied for Extraction. At this stage, drug components are isolated from hair at significantly lower levels than those used in other methodologies (like urine or saliva), making hair analysis a highly complex process.
Confirmation for any positive findings from Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with assumed positive outcomes are cleansed before confirmation as per necessity. The complete lab workflow from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair classification and with respect to the ISO / IEC 17025 certification.
