Hair testing is regarded as a robust method for identifying drug and alcohol usage. It offers an extensive timeline of substance use by capturing biomarkers within the fibers of the hair as it grows. When taken near the scalp, hair can reveal drug and alcohol use over an approximate three-month period. It is straightforward to gather, relatively hard to tamper with, and simple to transport.
A sample measuring 1.5 inches of roughly 200 hair strands (about the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, 150mg of the sample is advised. It is suggested to weigh the sample on a jeweler’s scale. Should scalp hair not be available, an equivalent amount of body hair can be gathered. Head hair refers solely to scalp hair, while body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The primary stages in processing a drug test result in a lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is integrated into the laboratory system. This step involves confirming that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and entering any additional information not supplied by an electronic chain of custody system.
Screening is a preliminary swift examination for drugs of abuse. While Screening effectively eliminates the possibility of drug usage for most samples affordably, a positive screen must be confirmed for it to be legally admissible. Any samples with presumptive positives in Screening require follow-up confirmation.
When a sample tests presumptively positive during the Screening phase, additional hair is taken from the original collection and prepared for Extraction. In this stage, drugs are removed from hair at considerably lower concentrations than in other testing methods (e.g., urine or oral fluid), contributing to hair drug testing being the most challenging methodology to conduct.
Positively screened results are verified via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation if necessary. The complete laboratory process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
