Hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair retains a historical record of alcohol and other drugs by embedding biomarkers within its fibers as it grows. When cut near the scalp, hair can offer a detection period of up to around 90 days for alcohol and other drugs. Hair collection is straightforward, generally resistant to tampering, and easy to transport.
A sample measuring 1.5 inches, consisting of about 200 hair strands (approximately the diameter of a #2 pencil) near the scalp, will yield 100mg of hair—the ideal quantity for both screening and confirmation. For EtG, additional tests, and/or more than 10-panel tests, it is advised to collect 150mg of the sample. We advise weighing the hair sample with a jeweler’s scale. Should scalp hair be unavailable, a comparable volume of body hair can be used. In reference to head hair, only scalp hair is implied. Body hair encompasses all other hair categories (facial, axillary, etc.).
Overview of the Process
The laboratory procedure for processing a drug test encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning concerns the preliminary handling of a sample within a laboratory's framework. This step includes confirming that the sample was correctly sealed and dispatched, generating a unique LAN (Laboratory Accessioning Number), and executing any supplementary data input not furnished by an electronic chain of custody system.
Screening entails an initial rapid assessment for substances of abuse. While Screening is a cost-efficient manner to exclude drug use in the majority of cases, a positive screening result requires confirmation for legal validity. Samples identified as potentially positive during Screening necessitate further confirmation.
Should a sample yield a presumptive positive in Screening, additional hair is taken from the original sample for preparation in Extraction. Here, drugs are extracted from hair at significantly lower concentrations compared to other techniques (like urine or oral fluid), making hair drug testing the most challenging methodology to execute.
Confirmation for any presumptive positive from screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Samples indicated as presumptive positives undergo washing before confirmation as needed. The complete laboratory process, spanning from Accessioning to Confirmation, is examined under both the CAP (College of American Pathologists) Hair designation and in conformity with ISO / IEC 17025 standards.
