Hair testing is increasingly recognized as an effective means for detecting drug and alcohol consumption. By capturing biomarkers within the strands of hair, it offers an extended history of substance use. Hair sampled near the scalp can provide a detection period for alcohol and drugs of up to three months. The collection of hair specimens is straightforward, challenging to tamper with, and convenient to transport.
An optimal sample consists of a 1.5-inch section containing roughly 200 hair strands, equivalent in thickness to a #2 pencil. This yields 100mg of hair, suitable for both screening and confirmation. In cases involving EtG, additional panels, or panels exceeding ten, a 150mg sample is advised. Utilizing a jeweler’s scale is recommended for weighing the specimen. In scenarios where scalp hair is not accessible, a matching quantity of body hair can be used. References to head hair specifically signify scalp hair. Body hair encompasses all other hair categories (such as facial or axillary hair).
Process Overview
The drug test result laboratory processing comprises the four primary stages of Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the phase of initially incorporating the specimen into the lab's system. This entails verifying appropriate sealing and shipment of the sample, generating a unique LAN (Laboratory Accessioning Number), and completing any requisite data entry absent in an electronic chain of custody setup.
Screening conducts an initial expedited assessment for substance abuse. While Screening provides a cost-efficient method for excluding drug use in most specimens, court acceptance of a positive screen necessitates confirmation. Samples flagged as presumptive positives during Screening require further confirmation.
For presumptive positives identified during Screening, additional hair is extracted from the initial sample for the Extraction process. At this stage, drugs are extracted from hair at significantly lower concentrations in comparison to other methodologies (such as urine or oral fluids), rendering hair drug screening a particularly intricate methodology.
Subsequent to a positive screen, Confirmation is executed using GC/MS, GC/MS/MS, or LC/MS/MS technologies. Necessary washing of presumptive positive samples occurs prior to Confirmation. The comprehensive lab procedure from Accessioning to Confirmation undergoes evaluation under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
Advantages of hair drug testing:
Limitations:
Note: Despite the common term "hair follicle tests," this test analyzes the hair strand itself rather than the hair follicle situated beneath the scalp.
