Hair testing is recognized as a formidable method for identifying substance use. Hair captures a longitudinal profile of alcohol and drug intake by embedding biomarkers within the hair's growing strands. When clipped close to the scalp, hair can offer an approximate 3-month window for detecting alcohol and drugs. Its collection is straightforward, alteration is challenging, and shipping is convenient.
A sample of 1.5 inches consisting of roughly 200 hair strands (comparable to a #2 pencil's width) nearest to the scalp provides 100mg of hair, which is the ideal amount for both screening and confirmation. For EtG, add-ons, or beyond 10-panel tests, 150mg of hair is advised. It is recommended to measure the specimen using a jeweler's scale. In the absence of scalp hair, a similar quantity of body hair can be gathered. References to head hair specifically denote scalp hair. Body hair includes all alternative hair types (such as facial or axillary hair).
Process Overview
The laboratory process for a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary incorporation of a sample into a lab's system. It entails checking that the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and inputting additional data not covered by an electronic chain of custody system.
Screening provides an initial drug abuse evaluation. While Screening is a cost-efficient approach to rule out most drug use, a positive finding requires confirmation for legal acceptance. Any presumptive positives in Screening need a follow-up confirmation.
Upon a presumptive positive in the Screening step, additional hair is extracted from the initial sample and readied for Extraction. Here, drugs are extracted from hair at much lower concentrations than in other methods (such as urine or oral fluid), highlighting why hair drug screening is particularly complex.
Confirmation for any positive Screening is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with preliminary positives are cleansed prior to confirmation as necessary. The whole process from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair recognition and accreditation to ISO / IEC 17025 standards.
