Hair analysis is recognized as an effective mechanism for identifying substance and alcohol use. Hair can capture a long-term picture of substances including alcohol by embedding biomarkers within the strands. Collected close to the scalp, hair reveals approximately a 3-month exposure history for substances including alcohol. Collecting hair is straightforward, difficult to tamper with, and easily transported.
A 1.5-inch segment of around 200 hair strands (comparable to the size of a #2 pencil) near the scalp can produce 100mg of hair, which is the optimal amount for both screening and results verification. For EtG, additional tests, and/or assessments exceeding 10 panels, a 150mg sample is advised. We suggest weighing the sample with a jeweler's scale. If scalp hair can't be obtained, a similar amount of body hair can be used. When mentioning head hair, it pertains solely to scalp hair. Body hair encompasses all other types (facial, underarm, etc.).
Process Overview
The laboratory processing of a drug test result comprises four essential steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a specimen into a lab's system. It ensures the sample was correctly sealed and dispatched, assigns it a random LAN (Laboratory Accessioning Number), and completes any supplementary data not offered by an electronic chain of custody system.
Screening consists of an initial swift assessment for substance misuse. While it is economical to exclude drug usage in most samples, a positive screening result requires confirmation for court acceptance. Any samples that are presumptively positive at the Screening stage necessitate further confirmation.
When a sample shows a presumptive positive during Screening, additional hair is extracted from the initially collected specimen for Extraction. In this step, substances are removed from hair at concentrations much lower than in other methodologies (such as urine or oral fluid), making hair drug testing quite challenging.
Confirmation for any positive screening result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptive positive are cleansed before confirmation as necessary. The comprehensive lab procedure from Accessioning to Confirmation undergoes review under the CAP (College of American Pathologists) Hair certification and adheres to ISO / IEC 17025 standards.
