Hair Follicle Drug Testing - Campia, WI

What it is, How it works

The detection of drugs and alcohol through hair testing is now regarded as a highly effective approach. Hair captures long-term usage data by embedding biomarkers within its growing fibers. When sampled from the scalp, hair can reveal a drug and alcohol history stretching back about three months. The collection process is straightforward and the sample is tough to tamper with, plus it’s convenient to mail.

A 1.5-inch segment consisting of approximately 200 hair strands (roughly the size of a #2 pencil) from near the scalp offers 100mg of hair, which is considered the optimal amount for effective screening and confirmation. For EtG assessments, additional tests, and/or those exceeding 10 panels, a quantity of 150mg is preferable. We advise using a jeweler’s scale for measuring the sample. In cases where scalp hair is absent, a proportional amount of body hair can be utilized. When discussing head hair, it's specific to scalp hair. Body hair covers all other types (facial, axillary, etc.).

Process Overview

The drug testing process in the lab consists of four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the step where a sample is initially integrated into the lab's system. This process involves ensuring the sample's seal and shipment were intact, assigning it a random Laboratory Accessioning Number (LAN), and filling in any data not provided by an electronic chain of custody protocol.

Screening acts as a preliminary evaluation for the presence of drug abuse. Although cost-effective for eliminating drug usage concerns in most samples, any positives from this stage must be validated for court use. Presumptive positives in Screening necessitate a further confirmation step.

For samples deemed presumptively positive during Screening, additional hair strands are taken from the original sample for the Extraction phase. Here, drugs are extracted at lower concentrations compared to alternative methods (e.g., urine or oral fluid), making hair drug testing a particularly challenging procedure.

All positive findings from screening undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, samples that are presumptively positive are cleansed based on requirements. The entire procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug testing can reveal substance use up to 90 days, while urine testing has a more limited timeframe.
• Hard to manipulate: The difficulty of altering hair test results enhances their reliability.
• Tracks historical usage: Offers insight into drug use patterns over time, not just recent consumption.

Limitations:

• Cannot identify recent use: Drugs typically take 5-7 days to become traceable in hair samples.
• Expense: Hair drug tests tend to be more costly compared to other testing techniques.
• Result variability: Factors like hair color and individual hair growth differences can influence metabolite levels in hair.

Note: Tests often termed "hair follicle tests" actually assess the hair strand above the scalp—not the underlying hair follicle.

Why Hair Follicle Testing Beats Urine Testing

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.
