Hair analysis has emerged as an effective method for detecting substance and alcohol consumption. Hair can provide an extended history of drug and alcohol use by embedding biomarkers within the growing hair fibers. When collected close to the scalp, hair can present a detection period of up to nearly three months for alcohol and other substances. The collection of hair is straightforward, relatively tamper-resistant, and convenient to transport.
A 1.5-inch segment consisting of around 200 hairs (about the diameter of a #2 pencil) nearest to the scalp yields approximately 100mg, which is the ideal amount for both screening and confirmation purposes. For EtG, additional tests, or more than 10-panel assessments, a 150mg sample is advised. Measuring the sample with a jeweler’s scale is recommended. If there is no scalp hair, an equivalent quantity of body hair can be collected. When referring to head hair, it specifically denotes scalp hair. Body hair encompasses all other types of hair (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning incorporates the initial integration of a sample into a lab system. This process verifies that the sample is properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and fills in any supplementary data not included by an electronic chain of custody protocol.
Screening provides an initial assessment for drug presence. Although screening is a cost-effective method to exclude drug usage for most samples, a positive screening result requires confirmation for court admission. Any samples that are presumptively positive at this stage necessitate additional confirmation.
In cases of presumptive positives during Screening, more hair is extracted from the initial sample for further processing in the Extraction phase. Here, substances are extracted from hair at a significantly lower concentration than other methods (such as urine or oral fluid), making hair drug screening the most complex method to execute.
Any positive screening outcomes undergo confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation as required. The lab process from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
