Utilizing hair testing proves effective for ascertaining drug and alcohol consumption. Hair strands capture markers of substance use, offering a prolonged timeline by encapsulating the indicators within the strand’s fibers. Hair gathered near the head's surface can show a detection span of up to about three months for alcohol and other substances. Collection is straightforward, the sample is fairly resistant to tampering, and shipment is uncomplicated.
A hair sample measuring 1.5 inches, containing around 200 strands and comparable in size to a standard pencil, will weigh approximately 100mg, fitting for analysis and validation. For EtG tests, supplementary screenings, or assessments exceeding 10-panel tests, a 150mg sample is advisable. Use of a jeweler’s scale is recommended to weigh the hair. If scalp hair cannot be obtained, the equivalent amount of body hair can be used as a substitute. The term 'head hair' pertains solely to scalp hair. 'Body hair' covers all other types (such as facial, axillary, etc.).
Process Overview
There are four crucial stages in processing a drug test at the lab: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the process of inputting the sample into the lab's system. It ensures the sample's packaging and transportation were conducted correctly, assigns a random LAN (Laboratory Accessioning Number), and fills in any data gaps not covered by an electronic tracking system.
Screening performs an initial assessment for drugs. While cost-efficient and effective for most, a positive result in Screening necessitates additional confirmation to hold validity in legal proceedings. Any screenings indicating presumptive positives require further verification.
A presumptive positive result in Screening leads to additional hair being extracted from the original sample for the Extraction phase. Here, drugs are isolated at lower concentrations compared to methods like urine or oral fluid tests, necessitating more sophisticated techniques in hair analysis.
Confirmation of any positive results from Screening is carried out using methods such as GC/MS, GC/MS/MS, or LC/MS/MS. All positive samples undergo washing before confirmation as determined necessary. The entire spectrum from Accessioning to Confirmation is assessed under CAP (College of American Pathologists) standards and compliant with ISO / IEC 17025 standards.
