Hair analysis is now regarded as an effective method for identifying drug and alcohol consumption. Hair offers an extended history of substance use by embedding biomarkers within the strands as they grow. When obtained near the scalp, hair can reveal up to about a 90-day timeline for detecting drugs and alcohol. This method is easy to obtain, somewhat resistant to tampering, and convenient to transport.
A 1.5-inch sample comprising around 200 hairs (approximately the thickness of a #2 pencil) from the scalp delivers 100mg, which is ideal for testing and validation. For EtG, additional tests, and/or screenings beyond 10 panels, a sample of 150mg is advised. Utilizing a jeweler’s scale to measure the sample is suggested. If head hair isn't available, a similar quantity of body hair can be substituted. By “head hair,†we mean only scalp hair. "Body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test outcomes includes four steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary processing of a specimen in a laboratory's system. This includes ensuring the sample was properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and finishing any extra data input that isn't automatically supplied by an electronic chain of custody system.
Screening entails a preliminary assessment for drugs of misuse. While it's a budget-friendly approach to exclude drug usage for most samples, a positive result requires validation to be court-admissible. Samples that show a preliminary positive in Screening must undergo further confirmation.
If a sample shows a preliminary positive in Screening, additional hair is taken from the initial sample for Extraction. In this stage, drug compounds are removed from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug testing one of the most challenging methodologies to carry out.
Confirmation of any positive screening outcome is done using GC/MS, GC/MS/MS, or LC/MS/MS. All preliminary positive samples are cleansed beforehand if necessary. The entire lab procedure from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair designation and accreditation of ISO / IEC 17025 norms.
