Hair testing is increasingly recognized as a potent method for detecting drug and alcohol consumption. Hair offers an extensive history of alcohol and drug use by embedding biomarkers within its growing fibers. When collected near the scalp, hair can reveal drug and alcohol usage up to an approximate 3-month period. This method involves easy collection, is relatively resistant to tampering, and is straightforward to transport.
A sample of 1.5 inches, consisting of roughly 200 hair strands (similar in size to a #2 pencil) near the scalp, provides about 100mg of hair, an ideal amount for both screening and confirmation. For EtG, add-on tests, and tests exceeding 10 panels, a specimen of 150mg is preferred. It is advisable to weigh the sample using a jeweler’s scale. If head hair is not available, a comparable amount of body hair can be gathered. References to head hair specifically pertain to scalp hair. Body hair includes any other body locations (such as facial or axillary hair, etc.).
Process Overview
The key phases in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial handling of a sample within a lab’s system, which encompasses checking the sample for proper sealing and shipment, assigning an arbitrary LAN (Laboratory Accessioning Number), and performing any supplementary data entry not managed by an electronic chain of custody system.
Screening represents a preliminary swift assessment for substance abuse. Although Screening is economical for preliminarily dismissing drug use in most cases, a positive result requires confirmation for legal acceptability. Any sample found presumptively positive in Screening mandates a subsequent confirmation.
Should a sample yield a presumptive positive during Screening, an additional quantity of hair is taken from the initial sample for preparation for Extraction. At this stage, drugs are isolated from the hair at a far lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug testing the most complex methodology.
Confirmation of any positive result from screening is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives are cleansed before confirmation, as necessary. The complete lab process from Accessioning to Confirmation is monitored under the CAP (College of American Pathologists) Hair designation, in addition to accreditation under ISO / IEC 17025 standards.
