Hair analysis is now acknowledged as a potent method for identifying drug and alcohol consumption. Hair delivers an extended history of alcohol and drug usage by encapsulating biomarkers within the growing strand's fibers. When harvested near the scalp, the hair can offer up to roughly a 3-month detection range for alcohol and drugs. Harvesting hair is straightforward, relatively hard to tamper with, and simple to transport.
A segment measuring 1.5 inches with approximately 200 hair strands (around the thickness of a #2 pencil) nearest to the scalp is needed to gather 100mg, the optimum amount for evaluation and verification. For EtG, additional tests, and tests exceeding 10 panels, 150mg of hair is suggested. It's advisable to weigh the hair sample on a jeweler’s scale. In cases where scalp hair is not available, an equivalent quantity of body hair can be utilized. By head hair, we mean scalp hair only. Body hair pertains to all other hair varieties (facial, axillary, and the like).
Procedure Synopsis
The primary stages in the laboratory assessment of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning denotes the preliminary input of a sample into a lab's system. This step involves ensuring the sample's seal and shipment were appropriate, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody protocol.
Screening serves as an initial rapid inspection for substance misuse. Although an economical method to rule out drug presence in most samples, a positive screen necessitates verification to hold up in court. Samples identified as presumptively positive in Screening require further confirmation.
Should a sample indicate a presumptive positive in Screening, additional hair is collected from the initial sample for Extraction preparation. Drugs are extracted from hair at a considerably lower concentration compared to other techniques (e.g., urine or oral fluid), which makes hair drug screening the hardest methodology to execute.
Confirmation for any positive screen result is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as required. The complete laboratory journey from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
