Hair Follicle Drug Testing - Mount Judea, AR

What it is, How it works

Hair analysis is increasingly recognized as an effective means for detecting drug and alcohol consumption. Hair acts as a record keeper by storing biomarkers within the fibers of the growing strand. When sourced close to the scalp, hair offers nearly a 3-month window for identifying alcohol and other drugs. Hair collection is straightforward, hard to tamper with, and convenient for shipping.

A 1.5-inch section consisting of about 200 strands (roughly the diameter of a #2 pencil) near the scalp yields 100mg—the optimal sample size for screening and verification. For EtG, additional tests, or panels exceeding 10 drugs, a 150mg sample is advisable. It’s recommended to weigh the sample using a jeweler’s scale. If scalp hair isn’t available, a comparable amount of body hair can be gathered. When mentioning head hair, we refer to scalp hair exclusively. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

There are four key steps in processing a hair drug test in the lab: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of integrating the sample into the lab’s system, involving verification of the sample’s proper sealing and shipping, assignment of a random LAN (Laboratory Accessioning Number), and completion of any missing data not covered by an electronic chain of custody.

Screening involves a prompt initial check for drugs. Although Screening is a frugal method to detect drug use in most samples, a positive result necessitates confirmation for legal purposes. Samples showing presumptive positive results in Screening must undergo further Confirmation.

In cases of a positive indication during Screening, additional hair is taken from the original sample for Extraction. This step involves extracting drugs from hair at lower levels than other methods like urine or oral fluid, which is why hair drug analysis is considered the toughest technique to execute.

Confirmation of any positive screening is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed if needed before Confirmation. The entire lab process from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair standards and accredited under ISO / IEC 17025 specifications.

Advantages of hair drug testing:

• Extended detection window: Hair tests identify drug use for up to 90 days, unlike urine tests with shorter detection windows.
• Cheating is difficult: Cheating a hair drug test is largely impractical, enhancing result accuracy.
• Historical data provision: It offers insight into drug use patterns over time, beyond just recent consumption.

Limitations:

• Cannot detect recent use: Drugs take approximately 5-7 days to manifest in hair.
• Cost: Hair tests generally cost more compared to other drug testing methods.
• Result variations: Elements like hair color and personal hair growth differences can influence drug metabolite levels in hair.

Note: Commonly called "hair follicle tests", the analysis examines the hair strand, not the follicle under 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. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
