Hair analysis is increasingly regarded as an effective means for uncovering the use of drugs and alcohol. The hair fiber captures biomarkers as it grows, providing a record of substance use over time. A sample taken near the scalp offers roughly a 90-day period for detecting alcohol and drugs. Hair sampling is straightforward, difficult to tamper with, and easy to transport.
A 1.5-inch segment comprising around 200 hairs (equivalent to a #2 pencil) collected close to the scalp will yield 100mg, ideal for initial screening and confirmation. For EtG, add-ons, and tests beyond 10 panels, it is advised to use 150mg of hair. We suggest using a jeweler’s scale for precise measurement. If no scalp hair is available, body hair in the same quantity can be used. We specifically refer to scalp hair as head hair, while body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory handling of a drug test result consists of four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial incorporation of a sample into a lab’s system, ensuring that the sample is properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any data entry not supplied by an electronic chain of custody system.
Screening serves as a preliminary check for drug abuses. Despite being a cost-efficient method to dismiss drug usage in most samples, a confirmed positive Screening is necessary for courtroom use. All samples with a presumed positive Screening result will need further confirmation.
Should Screening render a presumptive positive, more hair is taken from the original sample for Extraction. This phase extracts drugs from hair at a much lower density than other approaches (e.g., urine or oral samples), making hair drug screening the hardest methodology to conduct.
Confirmation for all positive Screening results utilizes GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples undergo washing as needed. Each phase of the laboratory procedure from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
