Hair Follicle Drug Testing - Parker, TX

What it is, How it works

Hair screening has emerged as an effective method for identifying drug and alcohol consumption. Hair retains a long-term record of substances by capturing biomarkers within the strands' fibers. When collected near the scalp, hair can offer roughly a 3-month detection range for alcohol and drugs. Hair collection is straightforward, relatively hard to alter, and simple to transport.

A 1.5-inch segment of approximately 200 hairs (similar in size to a #2 pencil) closest to the scalp yields 100mg of hair, the optimal sample for analysis and verification. For EtG, additional tests, and/or those beyond 10 panels, 150mg of the sample is advisable. We suggest weighing the specimen with a jeweler’s scale. If scalp hair is absent, a comparable amount of body hair can be used. By head hair, we mean scalp hair exclusively. Body hair encompasses all other hair types (such as facial, axillary, etc.).

Process Overview

The fundamental steps in laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a sample into a lab's system. This comprises ensuring the sample was properly sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and finishing any extra data entry not managed by an electronic chain of custody framework.

Screening entails an initial brief check for substances of abuse. Although Screening is an economical method for excluding drug usage in most samples, a positive screen requires validation to be accepted in legal settings. Presumptive positive samples in Screening necessitate a subsequent confirmation.

If a sample shows presumptive positive results during Screening, additional hair is extracted from the original sample for Extraction. This phase involves extracting substances from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to conduct.

Confirmation of any positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. The complete process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug screenings can identify drug use up to 90 days, surpassing the shorter detection period of urine tests.
• Difficult to deceive: Hair drug screenings are hard to deceive, ensuring more reliable outcomes.
• Offers historical insights: Provides a timeline of drug use over time rather than just recent consumption.

Limitations:

• Cannot identify recent use: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Typically more costly than other testing methods.
• Result variability: Variables like hair color and individual growth differences can influence metabolite concentrations in hair.

Note: Despite being referred to as "hair follicle tests", the analysis focuses on the hair strand, 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. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
