Hair Follicle Drug Testing - Cavour, WI

What it is, How it works

Hair analysis is now recognized as an effective method for identifying alcohol and drug consumption. The inherent markers within hair strands provide a long-term record of substance use. If collected near the scalp, hair samples can potentially offer a 3-month window for detecting drugs and alcohol. Hair collection is straightforward, not easily tampered with, and convenient to transport.

A 1.5-inch section containing approximately 200 hair strands (akin to the width of a #2 pencil) near the scalp yields a 100mg sample, the optimal amount for both initial screening and subsequent confirmation. For EtG, extended panels, and/or tests exceeding 10 panels, a 150mg specimen is suggested. We advise using a jeweler's scale for weighing the sample. If the head hair is not available, an equivalent amount of other body hair can suffice. Here, head hair specifically refers to hair on the scalp, while body hair encompasses other types (facial, axillary, etc.).

Process Overview

The leading stages in lab processing for a drug test include Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, a sample is first logged into the lab's database. This step ensures the sample's proper sealing and shipping, assigns a non-sequential LAN (Laboratory Accessioning Number), and completes any supplemental data entry if not covered by an electronic chain of custody system.

Screening acts as an initial, quick examination for drug presence. Although Screening offers an economical approach to negate drug use for most samples, legal acceptance requires a positive result to be confirmed. Samples presumed to be positive in this phase need secondary confirmation.

Should results be positive in the Screening phase, additional hair is extracted from the original sample for the Extraction process. During Extraction, drugs are isolated from hair at a lower concentration compared to other methods (e.g., urine or saliva), thus making hair drug testing more technically challenging.

Positive findings from the screening are validated through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples presumed to be positive undergo a cleansing protocol prior to final confirmation. The entire lab process, from Accessioning to Confirmation, is conducted under the guidelines of both the CAP (College of American Pathologists) Hair certification and compliance with ISO / IEC 17025 standards.

Benefits of hair drug analysis:

• Extended detection period: Hair tests can reveal drug use for up to 90 days, as opposed to the shorter timeframe of urine tests.
• Test integrity: The difficulty in manipulating hair tests ensures more reliable results.
• Trends analysis: Capable of illustrating a history of drug usage over time, rather than recent use alone.

Drawbacks:

• Not suitable for detecting recent use: Drugs generally become evident in hair after around 5-7 days.
• Expense: Hair tests tend to be pricier than other drug detection methods.
• Result variability: Factors like hair color and personal hair growth differences can impact drug metabolite levels in hair.

Note: Commonly dubbed "hair follicle tests,” the examination targets 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.
