Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drugs by embedding biomarkers within the shaft of the hair as it grows. When hair is taken near the scalp, it can offer an approximate 3-month timeframe for detecting alcohol and other substances. Hair is straightforward to collect, challenging to tamper with, and simple to transport.
A 1.5-inch segment of around 200 strands of hair (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is a perfect quantity for both initial testing and verification. For EtG, additional testing, and/or assessments exceeding 10 panels, 150mg is advisable. We suggest using a jeweler’s scale for weighing the sample. If scalp hair is unavailable, a comparable volume of body hair is acceptable. Regarding head hair, we are referencing only scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).
Process Overview
The key stages in the lab handling of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary handling of a sample within a lab’s framework. This entails verifying that the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data entry absent from an electronic chain of custody system.
Screening involves an initial rapid assessment for drugs of abuse. While Screening is a cost-effective means to exclude drug use on most samples, a positive screen requires confirmation for legal acceptability. Any samples that are tentatively positive in Screening necessitate a subsequent confirmation.
If a sample tests presumptively positive at the Screening phase, additional hair is taken from the original specimen and prepared for Extraction. In this phase, drug extracts from hair at lower concentrations than other techniques (e.g., urine or oral fluid), which is why hair drug screening is considered the most challenging method to conduct.
Confirmation of any positive screen result is done through GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleaned prior to confirmation when needed. The complete lab procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair specification and ISO / IEC 17025 standards of accreditation.
