Hair examinations have emerged as a potent method for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and other substances by embedding biomarkers within the strands of hair as it grows. When cut close to the scalp, hair offers a detection window of up to roughly three months for alcohol and drugs. It's straightforward to collect, somewhat challenging to tamper with, and conveniently transportable.
A sample measuring 1.5 inches, consisting of approximately 200 strands of hair (comparable to the thickness of a #2 pencil) near the scalp, will yield 100mg of hair, which is the preferred sample size for testing and confirmation. For EtG, expanded panels, and/or examinations exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale for weighing the specimen. Should scalp hair be inaccessible, a similar quantity of body hair can be gathered. By head hair, we mean scalp hair exclusively. Body hair pertains to every other hair type (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the preliminary handling of a sample within a laboratory’s framework. This step verifies the sample's proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry absent in an electronic chain of custody system.
Screening entails a rapid preliminary evaluation for drugs of abuse. While Screening is an economical strategy to eliminate drug usage in most samples, a positive result from Screening requires confirmation to be court-admissible. Any sample presumptively positive in Screening mandates secondary confirmation.
When a sample is presumptively positive in the Screening phase, an additional quantity of hair is extracted from the initial sample and readied for Extraction. This stage extracts drugs from hair at significantly lower concentrations compared to other methods (for example, urine or oral fluid), which makes hair drug screening one of the most challenging methodologies.
Confirmation of any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Washing of all presumptive positive samples is done prior to confirmation as required. Each part of the laboratory process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation.
