Perceived as a robust method, hair testing stands out for detecting drug and alcohol consumption. Hair strands capture biomarkers in their fibers, offering an extended timeline of drug or alcohol consumption. When taken near the scalp, hair can grant a detection frame of approximately three months for substances. It’s easy to collect, harder to tamper with, and simple to transport.
A 1.5-inch sample, roughly 200 strands (the approximate size of a #2 pencil) next to the scalp, assures about 100mg of hair, which is perfect for analysis and confirmation. For EtG and add-ons over 10 panels, a 150mg sample is advised. Using a jeweler’s scale for weighing is suggested. If no scalp hair is available, a similar volume of body hair is acceptable. "Head hair" indicates scalp hair alone, whereas "body hair" includes other hair types like facial or axillary hair.
Process Overview
Drug test result processing in a lab comprises Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves inputting the sample into the lab’s system initially. This phase ensures proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any missing information not included in an electronic chain of custody protocol.
Screening provides a quick initial assessment for drugs of abuse. Although cost-efficient for ruling out usage across most samples, positive screen results need confirmation for court validity. Any samples presumed positive during Screening require another confirmation step.
In cases of presumptive positivity during Screening, further hair is extracted from the original specimen for Extraction. Drugs are drawn out at a much lower concentration than other methods like urine or oral fluid, presenting why hair drug testing is particularly challenging.
Confirmatory analysis for any positive result employs GC/MS, GC/MS/MS or LC/MS/MS techniques. Presumptive positives undergo a wash before confirmation if required. The entire procedure, from Accessioning through Confirmation, is evaluated under both CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
