The use of hair testing has become recognized as an effective means for identifying drug and alcohol consumption. Hair offers an extended history of alcohol and other drugs by capturing biomarkers within the fibers of the growing hair strand. When collected adjacent to the scalp, hair can provide nearly a 3-month window of detection for alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and simple to transport.
A 1.5-inch sample consisting of about 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp offers 100mg of hair, which is the optimal amount for screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a sample of 150mg is advised. It is suggested to measure the specimen using a jeweler's scale. If scalp hair is unavailable, a comparable amount of body hair can be used. In context, head hair refers solely to scalp hair, while body hair encompasses all other types (such as facial, underarm, etc.).
Process Overview
The primary stages in laboratory analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial incorporation of a sample into a laboratory's system. This process includes ensuring the sample was properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry not already provided by an electronic chain of custody system.
Screening involves a preliminary assessment for drugs of abuse. While Screening is a cost-effective approach to eliminate drug usage in most samples, a positive screen requires confirmation for legal admissibility. Any samples showing a presumptively positive result in Screening necessitate a secondary confirmation.
If a sample is determined to be presumptively positive during the Screening stage, additional hair is extracted from the initial specimen to prepare for Extraction. Here, drugs are extracted from hair at a significantly reduced concentration compared to other methods (such as urine or oral fluid), making hair drug testing the most challenging methodology to execute.
Confirmation of any positive screening result is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo a washing process before confirmation as required. The complete laboratory procedure from Accessioning to Confirmation adheres to the CAP (College of American Pathologists) Hair designation and maintains accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Though referred to as "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp.
