Hair testing is recognized as an effective method for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of the growing hair strand, hair serves as an archive for long-term alcohol and drug use. When hair is collected near the scalp, it provides an approximate 3-month detection window for substances. Collection of hair is straightforward, challenging to tamper with, and convenient to transport.
A sample of about 200 hair strands (around the size of a #2 pencil), measuring 1.5 inches closest to the scalp, yields 100mg of hair, which is optimal for screening and confirmation. For EtG, additional tests, or those beyond 10 panels, a specimen weight of 150mg is suggested. It's advisable to weigh the specimen using a jeweler’s scale. If scalp hair isn't accessible, a comparable quantity of body hair is collected. Reference to head hair pertains solely to scalp hair, whereas body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The core stages in processing a drug test result in a lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into a lab’s system. It involves ensuring that the sample was appropriately sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent in an electronic chain of custody system.
Screening entails a preliminary rapid test for drugs of abuse. Though cost-effective for ruling out drug usage in most samples, a positive screening result necessitates confirmation for legal admissibility. Samples with a presumptive positive result from Screening require further verification.
Should a sample show presumptive positivity in Screening, additional hair is taken from the initial specimen for Extraction. This phase involves extracting drugs from hair at lower concentrations than other methods (e.g., urine or oral fluid), thus making hair drug screening the most challenging methodology.
Confirmation of any positive screening outcome is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation, as needed. The entire process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
