Hair Follicle Drug Testing - Bernice, OK

What it is, How it works

Recognized as an essential method for detecting drug and alcohol consumption, hair analysis captures long-term evidence of substances by embedding biomarkers within the hair’s fiber as it grows. A close-to-scalp sample effectively offers up to a 3-month timeframe for identifying drug and alcohol use. The collection process is straightforward, with a low risk of tampering, and the samples are easily transportable.

A section measuring 1.5 inches composed of approximately 200 hair strands (comparable to a #2 pencil in thickness) near the scalp provides a 100mg sample that is optimal for both screening and confirmation procedures. For tests such as EtG or those above 10 panels, a 150mg quantity is advisable. Using a jeweler’s scale to weigh the sample is recommended. In cases where scalp hair is unavailable, an equivalent quantity of body hair can be used. References to head hair pertain solely to scalp hair, whereas body hair includes all other types (such as facial or axillary hair).

Process Overview:

The laboratory process for processing a drug test result encompasses four principal phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning constitutes the preliminary integration of a sample into a lab’s system. It involves ensuring the sample’s secure sealing and proper shipping, assigning a random LAN (Laboratory Accessioning Number), and updating any missing data absent in an electronic chain of custody system.

The Screening phase entails an initial rapid assessment for substances of abuse. While efficient for excluding drug use in most cases, any positive screen must be confirmed to be legally credible. Samples showing a presumptive positive in Screening must undergo a follow-up confirmation.

When cases indicate a presumptive positive during Screening, additional hair is taken from the initial sample and readied for Extraction. The extraction process retrieves drugs from hair at notably lower concentrations than other techniques (such as urine or oral fluid), thus making hair testing the most challenging methodology.

Confirmation of any positive screening outcome utilizes methods such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleaned prior to confirmation when necessary. The comprehensive laboratory operation from Accessioning through Confirmation is subject to review under the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug screenings can identify drug use up to 90 days, unlike urine assessments which have shortened detection spans.
• Difficulty in subverting: The likelihood of subverting a hair drug test is very low, enhancing result accuracy.
• Historic insight: It offers insights into drug use patterns over an extended timeline, not just recent consumption.

Limitations:

• Recent consumption undetectable: Detecting drugs in hair takes roughly 5-7 days post-use.
• Expense: Hair drug screenings generally cost more than alternate testing methods.
• Result variability: Elements like hair color and personal hair growth differences can influence drug metabolite concentrations in hair.

Note: Though often termed as "hair follicle tests", analysis is conducted on the hair strand itself, 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis.
