Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair captures biomarkers in its growing strands, offering a prolonged record of alcohol and drug use. When taken from near the scalp, hair can indicate alcohol and drug presence for a period of up to approximately 3 months. The collection of hair is straightforward, resists tampering, and is easy to transport.
A 1.5-inch hair sample consisting of about 200 strands (roughly the thickness of a #2 pencil) from near the scalp provides 100mg of hair, which is the perfect amount for screening and validation. For EtG, additional testing, and/or tests beyond 10 panels, a sample of 150mg is suggested. It's advisable to weigh the sample on a jeweler’s scale. If there is no scalp hair, a comparable quantity of body hair can be taken. References to head hair pertain solely to scalp hair, while body hair encompasses other types of hair (facial, axillary, etc.).
Overview of the Process
The core procedures in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary handling of a sample within a lab's framework. This step verifies that the sample was properly sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and concludes any supplementary data entry absent in an electronic chain of custody system.
Screening is a foundational check for drugs of abuse. While Screening is a cost-efficient means to dismiss drug use in most samples, those rendering a positive result necessitate confirmation to be legally valid. Samples flagged as presumptively positive during Screening demand a secondary authentication.
Should a sample be deemed presumptively positive during Screening, additional hair is gathered from the initial sample and readied for Extraction. In this phase, substances are extracted from hair at a notably lower concentration compared to other methods (e.g., urine or oral fluid), which positions hair drug screening as a demanding methodology to execute.
Confirmation of any positive results from screening occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All samples considered presumptively positive are cleansed prior to confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair classification as well as the accreditation to ISO / IEC 17025 standards.
