The adoption of hair testing has become widely recognized as an effective method for identifying drug and alcohol consumption. Hair strands offer a prolonged timeline of alcohol and drug use by capturing biomarkers within the strands as they grow. If gathered near the scalp, hair can offer an approximate 90-day detection period for alcohol and drugs. Collecting hair is straightforward, quite resistant to tampering, and can be easily transported.
A 1.5-inch section of about 200 hair strands (comparable in thickness to a #2 pencil) nearest to the scalp provides 100mg of hair, which is the preferred quantity for both screening and confirmation. For EtG, added tests, and/or panels exceeding 10, 150mg of hair is advised. We suggest weighing the hair sample on a jeweler’s scale. Should scalp hair be lacking, a comparable amount of body hair can be used instead. When mentioning head hair, reference is made exclusively to scalp hair. Body hair encompasses all other hair forms (e.g., facial, axillary).
Process Overview
The drug test outcome processing in the lab entails four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning initiates the sample processing within a lab system. This phase ensures the sample was properly sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any data entry not covered by an electronic chain of custody system.
Screening offers a preliminary analysis for substance abuse. Although Screening serves as a cost-effective approach to eliminate drug use in most samples, confirmation of a positive screening is necessary for court validity. Samples that register presumptively positive in Screening require further confirmation.
When a sample is presumed positive during Screening, extra hair is extracted from the original sample and prepped for Extraction. This step involves retrieving drugs from the hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), highlighting why hair drug screening is the most intricate methodology.
Positive screening confirmations are executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo washing before confirmation as necessary. The comprehensive laboratory process from Accessioning through Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and meets the accreditation for ISO / IEC 17025 standards.
