Hair examinations are recognized as a potent method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drugs by embedding biomarkers in the growing hair strand's fibers. Gathered from near the scalp, hair can offer a detection range of up to roughly 3 months for alcohol and substances. Hair is straightforward to gather, relatively hard to tamper with, and simple to send.
A 1.5-inch section comprising about 200 hair strands (comparable to a #2 pencil's width) nearest to the scalp provides 100mg of hair, the optimal amount for both screening and verification. For EtG, additional tests, and/or those exceeding 10 panels, 150mg of the sample is advised. The sample should ideally be weighed on a jeweler’s scale. Should scalp hair not be available, an equivalent quantity of body hair can be collected. When referencing head hair, it pertains solely to scalp hair. Body hair denotes all other hair types (facial, axillary, etc.).
Process Overview
The key phases in laboratory drug testing processing are Accessioning, Screening, Extraction, and Confirmation.
Accessioning represents the initial processing phase where a sample is entered into a laboratory’s system. This phase includes confirming the sample's proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry absent in an electronic chain of custody system.
Screening offers an initial rapid assessment for substance misuse. Although Screening presents a cost-effective approach to negate drug usage in most samples, a positive screen requires confirmation to be valid in court. All samples that indicate a presumptive positive in Screening necessitate a secondary confirmation.
For samples suggesting a positive result in the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. During this stage, drugs are extracted from hair at a much lower concentration than other techniques (e.g., urine or oral fluid), pointing to the complexity of hair drug screening.
Confirmation of any positive screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation as required. The complete laboratory procedure, from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation.
