Hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of drugs and alcohol by preserving biomarkers within the strands of hair as it grows. When sampled near the scalp, hair can indicate alcohol and drug use extending back approximately 3 months. It is easy to collect, relatively hard to tamper with, and convenient for shipping.
A sample measuring 1.5 inches from about 200 hair strands (roughly the diameter of a #2 pencil) nearest the scalp provides 100mg of hair, which is ideal for both screening and confirmation purposes. For EtG, additional tests, and/or panels exceeding 10, a specimen of 150mg is suggested. Use a jeweler’s scale to weigh the specimen accurately. If scalp hair isn’t an option, an equivalent quantity of body hair is acceptable. In discussions of head hair, we mean scalp hair solely, whereas body hair refers to all other hair types (e.g., facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial integration of a sample into the laboratory system. This comprises confirming proper sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and performing any extra data entry not handled by an electronic chain of custody system.
Screening serves as a preliminary rapid assessment for substance abuse. Though Screening is a cost-effective means of excluding drug use across most samples, a positive screen requires confirmation to hold up in court. Any samples with presumptive positives during Screening necessitate further confirmation.
For samples displaying presumptive positives in the Screening phase, additional hair is extracted from the original specimen and readied for Extraction. This step involves extracting drugs from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), which is why hair drug testing is the most complex methodology.
Confirmation of any positive screening outcomes is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Every presumptive positive sample undergoes washing prior to confirmation as required. The whole laboratory procedure from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.
