Analyzing hair samples has emerged as an effective method for identifying drug and alcohol consumption. Hair can capture and encapsulate the traces of alcohol and various substances within the fibers of the hair as it naturally grows. If collected near the scalp, hair can reveal drug and alcohol intake over a span of roughly three months. This method is straightforward for collection, relatively challenging to tamper with, and convenient for transportation.
A sample measuring 1.5 inches, consisting of around 200 hair strands (comparable in size to a #2 pencil), cut nearest the scalp, will yield 100mg of hair, which is optimal for both screening and confirmation. For tests involving EtG, additional elements, or more than 10 panels, a sample of 150mg is advisable. A jeweler’s scale is recommended for weighing the hair. Should scalp hair be unavailable, an equivalent portion of body hair is acceptable. In our context, head hair specifically refers to scalp hair, whereas body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The process of laboratory analysis for a drug test is divided into four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial phase where a sample is logged into the laboratory’s system. This step ensures the sample's proper sealing and shipment, assigns it a unique LAN (Laboratory Accessioning Number), and addresses any supplementary data that isn't covered by an electronic chain of custody system.
Screening involves a preliminary quick analysis to identify drugs of abuse. Though cost-effective for identifying drug use in most samples, positive findings in Screening must be further verified for legal proceedings. Any presumed positive results during Screening mandate a confirmatory step.
Should a sample yield a presumptive positive during Screening, additional hair from the initial sample is used for Extraction. This step isolates drugs from hair at considerably lower levels than those detected through other methods like urine or oral fluid, establishing hair drug testing as particularly intricate.
Confirming any positive results from Screening is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All samples preliminarily positive are cleansed before confirmation when necessary. The entire procedure, from Accessioning to Confirmation, is conducted under the guidelines of CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.
