Hair assessments have become recognized as a potent resource for identifying drug and alcohol consumption. Hair retains a comprehensive history of alcohol and other substances by encapsulating biomarkers within the fibers of the developing hair strand. When gathered near the scalp, hair offers up to roughly a 3-month detection span for alcohol and various drugs. Hair collection is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch portion consisting of approximately 200 hair strands (comparable to the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample for testing and validation. For EtG, additional tests, and/or testing beyond 10 panels, a 150mg specimen is advised. It's suggested to use a jeweler’s scale to weigh the specimen. If scalp hair is absent, an equivalent quantity of body hair can be collected. When discussing head hair, it pertains exclusively to scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The four fundamental stages involved in lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the preliminary processing of a specimen into a laboratory's system. This incorporates verifying the sample was appropriately sealed and dispatched, allotting a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry not covered by an electronic chain of custody system.
Screening entails an initial rapid assessment for illicit substances. Although Screening serves as a cost-efficient method to exclude drug use in the majority of specimens, a positive screen necessitates confirmation to be legally admissible. Samples that presumptively test positive in Screening do require secondary validation.
If a specimen is presumptively positive during the Screening phase, additional hair is obtained from the initial sample and prepared for Extraction. During this step, substances are extracted from hair at significantly lower concentrations compared to other methodologies (e.g., urine or oral fluid), making hair drug testing the most challenging method to perform.
Confirmation of any positive Screening outcome is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. Presumed positive samples are cleansed prior to confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
