Hair analysis is now considered a robust method for detecting drug and alcohol consumption. The hair captures a prolonged record of alcohol and other substances by embedding biomarkers within the strands as they grow. When collected from near the scalp, hair can offer up to a three-month timeline for detecting alcohol and drugs. It is straightforward to collect, rather tricky to tamper with, and convenient to send.
A 1.5-inch specimen of roughly 200 hair strands (comparable to the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, which is ideal for both screening and confirmation. For EtG or tests beyond 10 panels, 150mg is suggested. It's advisable to weigh the sample using a jeweler’s scale. Should scalp hair be inaccessible, an equivalent quantity of body hair may be used. When mentioning head hair, it specifically means scalp hair. Body hair includes other types like facial and axillary hair.
Process Overview
The core steps in processing a drug test in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the introductory step where a sample is logged into a lab’s framework. This process ensures the sample is sealed and delivered correctly, assigns a random LAN (Laboratory Accessioning Number), and fills in any additional details not filled by an electronic chain of custody.
Screening provides an initial scan for drug presence. Though Screening is economical for discounting drug use in most cases, a detected positive result must be verified for legal acceptability. Samples with presumptive positives in Screening mandate subsequent confirmation.
Should a specimen indicate positive in Screening, more hair is extracted and set for Evaluation. During this phase, substances are extracted from hair at a significantly lower level than other methods (like urine or oral fluids), establishing hair drug testing as one of the most challenging methods to execute.
Confirmation of any pretended positive result is attained via GC/MS, GC/MS/MS or LC/MS/MS. Samples that test presumptive positive undergo washing before confirmation as necessary. The complete laboratory process from Accessioning through Confirmation is assessed through both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.
