Recognized widely, hair testing serves as a robust method for identifying drug and alcohol consumption. Offering a historical record of substance use, hair captures markers within the strands as they grow. When collected near the scalp, hair can reveal a detection period of up to about three months for alcohol and drugs. Hair collection is easy, hard to tamper with, and straightforward to transport.
A optimal sample for screening and verification involves a 1.5-inch hair piece, comprised of roughly 200 hair strands (about the size of a #2 pencil), closest to the scalp yielding 100mg of hair. For EtG, enhancements, or testing surpassing 10 panels, 150mg is preferable. Using a jeweler’s scale for specimen weighing is advised. Should scalp hair be inaccessible, a proportional amount of body hair is acceptable. References to head hair specify scalp hair exclusively, whereas body hair includes all other types (facial, axillary, etc.).
Process Overview
The four fundamental steps in processing a drug test result in the laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the sample’s initial integration into the laboratory's system. This process ensures the sample was sealed and transported correctly, assigns a random LAN (Laboratory Accessioning Number), and fills in any missing data not captured by an electronic chain of custody system.
Screening provides an initial rapid evaluation for drug use. It’s a cost-efficient means to rule out drug consumption for most samples; however, a positive screen necessitates confirmation for legal admissibility. Samples testing positive in Screening require further validation.
Upon presumptive positives in Screening, additional hair is extracted from the specimen for Extraction preparation. Drugs are withdrawn from hair at much lower concentrations than other techniques (e.g., urine or oral fluid), making hair drug tests the most challenging to execute.
Confirmation for any positive screening result is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as necessary. From Accessioning to Confirmation, the entire lab process is audited following the CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.
