Hair Follicle Drug Testing - Twin Valley, MN

What it is, How it works

Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. Hair fibers ensnare biomarkers, offering a detailed long-term history of alcohol and drugs as hair strands grow. When clipped near the scalp, they reveal up to a 3-month detection window for substances. Hair is easy to collect, challenging to tamper with, and straightforward to transport.

A 1.5-inch portion containing about 200 hairs (approximately a #2 pencil’s thickness) near the scalp provides 100mg of hair, the optimal quantity for testing. For EtG, add-ons, or tests over 10 panels, 150mg is advisable. It's best to measure the sample using a jeweler’s scale. If scalp hair isn't accessible, a similar quantity of body hair may be used. References to head hair pertain solely to scalp hair, whereas body hair refers to other hair types (e.g., facial, axillary, etc.).

Process Overview

The process involves four principal laboratory stages: Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, samples are initially processed into a lab system. This step confirms the sample's proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and finishes any data not included in an electronic chain of custody system.

Screening conducts a preliminary check for drugs of abuse. Although Screening economically dismisses drug use in most samples, a positive outcome must undergo confirmation to be legally admissible. Any samples showing preliminary positivity in Screening need secondary confirmation.

If Screening indicates a presumptive positive, additional hair is taken from the original sample and readied for Extraction. In Extraction, drugs are separated from hair at significantly lower concentrations than in other techniques (e.g., urine or oral fluid), underlining hair drug screening's complexity.

For any positive screening, Confirmation uses GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples receive pre-confirmation washing as required. The complete laboratory process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests reveal drug use over up to 90 days, unlike urine tests with shorter detection periods.
• Hard to falsify: Circumventing a hair test is quite challenging, ensuring more reliable results.
• Historical use: It provides a drug use pattern over time, rather than just recent use.

Limitations:

• Cannot find recent use: It requires about 5-7 days for drugs to become detectable in hair.
• Price: Hair tests generally incur higher costs than other drug testing methods.
• Variability: Factors like hair color and personal hair growth differences can influence drug metabolite concentration in hair.

Note: Although often labeled "hair follicle tests", the analysis focuses on the hair strand, not the scalp hair follicle.

Why Hair Follicle Testing Beats Urine Testing

In Twin Valley, MN, the superiority of hair follicle testing over traditional urine testing is apparent. Hair analysis offers extensive detection capabilities, proving to be a more accurate and reliable choice.

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.
