Hair Follicle Drug Testing - Dassel, MN

What it is, How it works

Hair analysis is now recognized as a robust method for identifying alcohol and drug usage. Hair strands capture biomarker evidence as they grow, offering a timeline of drug and alcohol consumption. When hair is sampled near the scalp, it can indicate substance use over roughly three months. The hair collection process is straightforward, hard to tamper with, and convenient for shipping.

A sample measuring 1.5 inches and consisting of around 200 hair strands, equating to a #2 pencil's girth, provides 100mg of hair, which is optimal for initial screening and subsequent validation. For extended panels or EtG add-ons, a specimen weight of 150mg is advisable. We suggest utilizing a jeweler’s scale for precise measurement. If head hair is not available, an equivalent quantity of body hair may be used. When we refer to head hair, we mean only scalp hair. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The drug testing process in a laboratory consists of four crucial phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the phase where a sample is entered into the lab's system. The process ensures that the sample is properly sealed and transported, assigns it a random LAN (Laboratory Accessioning Number), and completes any necessary data entry not covered by an electronic custody tracking system.

Screening serves as a preliminary fitness test for detecting substances of abuse. While it's an economical way to discount drug presence in most cases, a positive finding requires verification for legal admissibility. Any sample flagged as presumptively positive in Screening mandates further confirmation.

If Screening results in a presumptive positive, additional hair is extracted from the initial sample for the Extraction phase. This stage involves isolating drugs from hair at significantly lower levels compared to other procedures (e.g., urine or oral fluid), making hair drug screening the most complex method to execute.

Positive Screening outcomes are validated via GC/MS, GC/MS/MS, or LC/MS/MS. All samples labeled as presumptive positive undergo a cleansing step before confirmation as required. Every laboratory procedure from Accessioning through Confirmation is evaluated based on the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to 90 days, unlike urine tests with shorter detection periods.
• Hard to tamper with: Cheating a hair drug test is immensely challenging, ensuring more reliable results.
• Tracks usage history: It depicts drug usage patterns over time, not just recent intake.

Limitations:

• Doesn't show recent use: It takes approximately 5-7 days for drugs to emerge in hair.
• Expense: Hair drug tests tend to be costlier than other testing methodologies.
• Result variability: Variables like hair color and personal differences in hair growth can influence metabolite concentration.

Note: Although widely called "hair follicle tests," the procedure examines 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.

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.

Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols.
