Hair Follicle Drug Testing - Centrahoma, OK

What it is, How it works

The utilization of hair analysis has gained recognition as an effective means for identifying substances such as drugs and alcohol. Hair serves as a prolonged record of alcohol and other substances by embedding biomarkers within the strands as they grow. When sampled near the scalp area, hair can reveal usage patterns over an estimated three-month period for alcohol and drugs. It is straightforward to gather, relatively resistant to tampering, and simple to transport.

Collecting a sample measuring 1.5 inches from about 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp results in 100mg, which is optimal for both screening and affirmation. For EtG, supplement tests, and/or evaluations exceeding 10 panels, a recommendation of 150mg of the specimen is ideal. Utilizing a jeweler’s scale for specimen weighing is advised. In the absence of scalp hair, a similar quantity of body hair may serve the purpose. When mentioning head hair, it pertains solely to scalp hair. Body hair encompasses other types such as facial, axillary, etc.

Process Overview

The core stages in the lab examination of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial induction of a sample into a lab’s protocol. It encompasses ensuring the sample was securely sealed and dispatched correctly, allocating a random LAN (Laboratory Accessioning Number), and fulfilling any remaining data input absent in a digital chain of custody system.

Screening entails an initial cursory assessment for substances of misuse. Although it is a budget-friendly method to exclude drug usage in most samples, any positive findings from screening need corroboration for validity in legal contexts. Samples that test positive on screening necessitate subsequent confirmation.

For samples flagged as positive in the Screening phase, further hair is taken from the original specimen for Extraction. In this step, drugs are drawn from hair at a substantially lower prevalence than other methods (e.g., urine or oral fluid), making hair drug assessment the most challenging technique to conduct.

Verification of any preliminary positive screening outcome is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with initial positive results undergo washing before confirmation if necessary. The full lab procedure, from Accessioning to Confirmation, is thoroughly evaluated under the CAP (College of American Pathologists) Hair specification and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can trace substance use for as far back as 90 days, unlike urine tests with a more limited detection period.
• Hard to tamper with: The difficulty of altering hair drug tests results in greater accuracy.
• Gives historical insights: It illustrates a pattern of drug consumption over a stretch of time, rather than merely immediate use.

Limitations:

• Incapable of identifying recent usage: It requires roughly 5-7 days before substances become traceable in hair.
• Expense: Hair drug assessments tend to be pricier compared to alternative drug testing approaches.
• Result variations: Variables like hair hue and individual differences in hair development can influence the levels of drug by-products in the hair.

Note: While frequently labeled as "hair follicle tests", the analysis actually focuses on the strand of hair, not the follicle beneath the scalp

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.
