Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair acts as a long-term recorder of alcohol and other substances by integrating biomarkers into the strands as they grow. Clipping hair close to the scalp can offer an approximate three-month detection timeline for alcohol and drugs. This method allows for easy collection, limited potential for tampering, and straightforward shipping.
A 1.5-inch segment of around 200 hair strands (roughly the width of a #2 pencil) near the scalp yields 100mg, which is ideal for initial screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of hair is advisable. Using a jeweler’s scale to weigh the sample is recommended. If scalp hair is not accessible, a comparable amount of body hair can be used. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The key stages in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial setup of a sample within the lab's framework. This encompasses confirming the proper sealing and dispatch of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry not provided by an electronic chain of custody system.
Screening is a preliminary swift assessment for drugs of abuse. Although Screening is a cost-efficient method for excluding drug use in most samples, a positive result must be confirmed for legal acceptability. Any samples showing presumptive positives in Screening necessitate further confirmation.
For samples indicated as presumptively positive during Screening, additional hair is extracted from the original sample and prepped for Extraction. Drugs are extracted at a markedly lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.
Comprehensive confirmation of any positive screening result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, presumptive positive samples undergo necessary washing. The complete laboratory procedure from Accessioning to Confirmation is assessed according to CAP (College of American Pathologists) Hair criteria and accredited to ISO / IEC 17025 standards.
