Hair Follicle Drug Testing - Kiel, WI

What it is, How it works

Hair evaluations have emerged as an effective means for identifying drug and alcohol consumption. The hair captures a historical record of substances by embedding markers in the growing strand. When clipped near the scalp, hair can reveal substance use over an estimated 3-month period. Collection is straightforward, it is fairly resistant to tampering, and transport is simple.

A 1.5-inch snippet comprising approximately 200 hairs (comparable in girth to a #2 pencil) closest to the scalp provides 100mg, the ideal quantity for analysis. For EtG, additional tests, or panels exceeding ten, a 150mg sample is advisable. Use a jeweler’s scale for precise weighing. Should scalp hair be unavailable, a comparable amount of body hair can suffice. The term "head hair" denotes scalp hair specifically, while "body hair" pertains to all other categories (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial intake procedure for a sample into the lab’s system. It includes confirming the proper sealing and transport of the sample, assigning a random LAN (Laboratory Accessioning Number), and handling any further data input not addressed by an electronic chain of custody system.

Screening provides a preliminary overview for drug abuse indicators. Screening offers a cost-effective method to eliminate drug involvement in most cases; however, for legal acceptability, a positive result must undergo confirmation. Samples testing presumptively positive in Screening necessitate additional confirmation.

Should a sample exhibit presumptively positive results in Screening, additional hair is extracted from the original specimen for the Extraction phase. Here, drugs are extracted from hair at lower concentrations than other methods (e.g., urine or oral fluid), rendering hair drug evaluation particularly challenging.

Post-screening confirmation of positive results is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positives are cleansed as required. The full laboratory procedure from Accessioning through Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing reveals drug usage over as much as 90 days, unlike urine tests with a more limited timeframe.
• Difficult to evade: The accurate outcomes of a hair drug test are hard to tamper with.
• Offers usage pattern insights: Provides a timeline of substance consumption, not merely recent intake.

Limitations:

• Non-detection of recent usage: It generally takes drugs about 5-7 days to become detectable in hair.
• Expense: Hair drug assessments typically cost more than other drug testing methods.
• Result fluctuations: Drug metabolite concentrations in hair can be influenced by factors like hair color and individual growth variations.

Note: Referring to these as "hair follicle tests" is a misnomer since the analysis targets the strand rather than 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.
