Hair analysis is now acknowledged as a potent method for identifying drug and alcohol consumption. The structure of hair captures a long-term record of substances by embedding biomarkers within its growing strands. When taken near the scalp, the hair sample can offer roughly a 90-day detection period for both alcohol and narcotics. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.
A sample measuring 1.5 inches with around 200 hair strands (similar in size to a #2 pencil) nearest to the scalp yields 100mg of hair, ideal for testing. For EtG, additional evaluations, and/or tests beyond 10 panels, 150mg of the sample is advised. It is best to weigh the sample using a jeweler’s scale. If scalp hair is not available, a similar amount of body hair may be used. In references to head hair, we mean only scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The procedure for processing a drug test involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial handling of a specimen within the lab's workflow, including ensuring proper sealing and shipping of the sample, assigning it a LAN (Laboratory Accessioning Number) randomly, and fulfilling any additional data entry absent from an electronic chain of custody.
Screening is a preliminary assessment for substances of abuse. This cost-efficient measure helps exclude drug consumption in most specimens, but court-eligible results require confirmation. Samples that are potentially positive in Screening must undergo a second confirmation.
When a specimen tests potentially positive during Screening, more hair is extracted from the initial sample for the Extraction process. Here, substances are isolated from hair at much lower concentrations than other methods (e.g., urine or saliva), illustrating why hair testing is the most challenging technique to carry out.
GC/MS, GC/MS/MS, or LC/MS/MS methods conduct Confirmation of any positive Screening outcomes. Prior to Confirmation, all potentially positive samples are cleansed as necessary. The laboratory's entire procedure from Accessioning through Confirmation is overseen under the standards of both the CAP (College of American Pathologists) Hair classification and ISO/IEC 17025 accreditation.
