Hair Follicle Drug Testing - Grundy, VA

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol usage. Hair captures a long-term record of drugs and alcohol by securing biomarkers within its developing fibers. Hair collected near the scalp may reveal a detection timeline for alcohol and drugs extending up to about three months. Collecting hair is straightforward, relatively tough to tamper with, and hassle-free to transport.

A sample measuring 1.5 inches and consisting of roughly 200 hair strands (comparable to a #2 pencil thickness) taken nearest the scalp provides 100mg of hair, which is the optimal amount for both screening and verification. For EtG, additional tests, and tests exceeding ten panels, it is advisable to provide 150mg of the specimen. It's suggested to measure the specimen's weight using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair is acceptable. References to head hair specifically mean scalp hair. Body hair encompasses all other types, such as facial and axillary hair.

Process Overview

The path of processing a drug test in the laboratory encompasses four pivotal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial sample processing step managed within a laboratory’s system. This stage checks that the sample was correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and fulfills additional data entry requirements not included in an electronic chain of custody system.

Screening offers a preliminary, swift assessment for substance abuse. While it is an economical method to exclude drug usage from most samples, positive results in Screening require confirmation for legal admissibility. Therefore, samples that test presumptively positive in Screening must undergo further verification.

Following a presumptive positive result in the Screening phase, extra hair from the original sample is extracted for the Extraction stage. During Extraction, drugs are derived from hair at concentrations significantly less than those used in other testing methods like urine or oral fluid, contributing to hair drug screening’s complexity as a testing methodology.

Confirmation of any positive screening outcomes is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before Confirmation if necessary. The entire process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and conformance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair testing evidences drug usage for up to 90 days, unlike the shorter windows of urine testing.
• Hard to falsify: Cheating a hair drug test is exceedingly challenging, thus ensuring result accuracy.
• Historical tracking: It showcases a pattern of drug consumption over an extended period, rather than only recent usage.

Limitations:

• Recent usage detection: Drugs become apparent in hair within roughly 5-7 days post-use.
• Expense: Hair drug analyses are typically costlier than alternative drug testing approaches.
• Result variability: Influences like hair color and individual differences in hair growth can impact drug metabolite concentrations in hair.

Note: Although often termed as "hair follicle tests", the assessment itself examines the hair strand and 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.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis.
