Hair testing is increasingly recognized as a robust method for detecting drug and alcohol consumption. Hair offers an extended timeline of substance use by ensnaring biomarkers within its growing fibers. When obtained near the scalp, hair can reveal substance use over a period of up to three months. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A sample size of 1.5 inches from around 200 hair strands (comparable to a #2 pencil's width) near the scalp yields 100mg, an ideal amount for initial analysis and verification. For EtG, additional tests, and panels exceeding 10, a 150mg sample is advised. It's suggested to measure the sample on a jeweler's scale. In the absence of scalp hair, a similar quantity of body hair can be used. "Head hair" implies scalp hair exclusively, while "body hair" encompasses other types, such as facial and axillary.
Process Overview
The laboratory handling of a drug test result consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the sample's preliminary integration into the lab system. This step verifies correct sealing and shipment of the sample, allocates a unique LAN (Laboratory Accessioning Number), and completes data entry not covered by an electronic custody system.
Screening involves a preliminary check for substances. Though cost-effective for excluding drug use in most samples, positive screenings must be confirmed for legal acceptability. Samples showing potential positive results require further verification.
Should a sample show a presumptive positive at Screening, more hair from the initial collection is readied for Extraction. Here, substances are isolated from the hair at significantly lower concentrations compared to urine or oral fluid methods, highlighting the complexity of hair drug screening methodology.
Results deemed positive during Screening are corroborated through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are washed beforehand as necessary. Every stage from Accessioning to Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair standard and accreditation per ISO / IEC 17025.
