Hair examinations have emerged as a robust means for identifying substance and alcohol usage. Hair captures a long-term record of alcohol and other substances by embedding biomarkers within the fibers of the hair strand as it grows. When gathered near the scalp, hair embodies an approximately 3-month detection period for alcohol and drugs. Collection is straightforward, making tampering somewhat challenging, while also being convenient for shipping.
A hair sample measuring 1.5 inches, totaling roughly 200 strands, equivalent to the width of a #2 pencil, cut near the scalp, will yield 100mg of hair, the ideal quantity for screening and validation. For EtG, additional tests, or tests exceeding 10 panels, a 150mg sample is advised. We recommend using a jeweler's scale to weigh the specimen. Should scalp hair be unavailable, an equivalent amount of body hair may serve as a substitute. "Head hair" specifically denotes scalp hair, whereas "body hair" encompasses all other types (facial, underarm, etc.).
Process Overview
Handling a drug test result in the laboratory entails four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the sample's initial processing within a lab's framework. This step includes ensuring the sample’s proper sealing and shipping, assigning it a random LAN (Laboratory Accessioning Number), and completing any missing data entry not furnished by an electronic custody chain system.
Screening provides an initial rapid assessment for drugs of abuse. While Screening efficiently rules out drug use for most samples, a confirmation is necessary for a court-admissible positive result. Samples flagged as presumptively positive in Screening necessitate a secondary confirmation.
For samples tested presumptively positive during Screening, additional hair is extracted from the initial specimen and readied for Extraction. Here, drugs are withdrawn from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), establishing hair drug screening as the most complex method to execute.
Confirming any positive result from Screening is done through GC/MS, GC/MS/MS or LC/MS/MS. All samples that are presumptive positives undergo washing before confirmation if required. The entire lab procedure, from Accessioning to Confirmation, is subject to review under both the CAP (College of American Pathologists) Hair accreditation and the ISO / IEC 17025 standards.
