Hair analysis has gained recognition as an effective method for identifying substance use. Hair strands offer an extended timeline for detecting alcohol and other substances by embedding biomarkers within the hair's growing fibers. When taken near the scalp, hair samples can present an approximately three-month window for identifying alcohol and other substances. Hair collection is straightforward, relatively tamper-proof, and easy to transport.
A sample measuring 1.5 inches, consisting of roughly 200 hair strands (comparable to the thickness of a standard pencil), taken nearest the scalp, provides 100mg of hair, ideal for both screening and confirmation. For EtG, add-ons, and/or tests exceeding ten panels, a 150mg sample is preferred. We advise assessing the sample weight using a jeweler's scale. Should scalp hair be unavailable, an equivalent quantity of body hair may be used. References to head hair solely regard scalp hair, whereas body hair encompasses all other hair varieties (facial, underarm, etc.).
Process Overview
The primary stages in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial intake of a sample into the lab’s records. This phase ensures proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and inputs any additional data omitted by an electronic custody chain system.
Screening offers a preliminary assessment for substances of abuse. Although Screening is a cost-efficient method to exclude drug usage for most samples, a positive screen requires confirmation for court admissibility. Samples presumed positive in Screening necessitate further confirmation.
Samples that test presumptively positive in Screening undergo additional hair extraction from the initial sample for the Extraction stage. In this step, drugs are isolated from hair at significantly lower concentrations than other methods (e.g., urine or oral fluids), highlighting the complexity of hair drug testing methodology.
Confirmation of any positive screening result is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test presumptively positive are washed before confirmation as needed. The complete lab procedure, from Accessioning to Confirmation, is examined in line with the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
