Hair Follicle Drug Testing - Bloomfield Hills, MI

What it is, How it works

Hair analysis is increasingly recognized as an effective means to identify drug and alcohol consumption. Hair captures a long-term record of drug and alcohol presence by embedding biomarkers within the hair strand fibers as they grow. A sample taken close to the scalp can reveal drug and alcohol usage for a duration of up to about three months. Collecting hair is straightforward, less prone to tampering, and convenient for transport.

A 1.5-inch length of approximately 200 hair strands, roughly the diameter of a #2 pencil, cut closest to the scalp, generates 100mg of hair, which is optimal for initial screening and verification. For EtG, additional testing, and/or assessments beyond ten panels, 150mg of hair is advisable. We suggest using a jeweler's scale for precision in weighing the sample. When scalp hair is unobtainable, an equivalent volume of body hair can be substituted. Head hair refers specifically to scalp hair, while body hair includes all other types (like facial, axillary, etc.).

Process Overview

The laboratory procedure for processing a drug test outcome consists of four stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the introduction of a sample into a lab's framework. This step involves ensuring that the sample was sealed and transported correctly, generating a random LAN (Laboratory Accessioning Number), and completing any supplemental data entry absent from an electronic chain of custody system.

Screening serves as an initial rapid assessment for drug presence. Although Screening is economical for initially excluding drug use in most samples, a positive result must be confirmed for legal acceptability. Any samples that test presumptively positive during Screening necessitate further confirmation.

When a sample shows a presumptive positive result in the Screening stage, additional hair from the original collection is utilized for Extraction. During this process, drugs are isolated from hair at concentrations much lower than in other methods (e.g., urine or oral fluid), which explains why hair drug testing presents the most significant challenge in methodology.

Confirmed positive results from Screening undergo verification using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptively positive samples are cleansed before confirmation when necessary. The complete lab procedure from Accessioning to Confirmation adheres to the guidelines set by both CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests that have a brief detection timeframe.
• Difficult to manipulate: Hair drug tests are challenging to falsify, leading to more reliable results.
• Offers a usage timeline: They can illustrate a drug usage pattern over months, not just recent consumption.

Limitations:

• Inability to detect recent use: Hair needs about 5-7 days for drugs to become detectable.
• Expense: Hair drug tests typically cost more than other testing methods.
• Result variability: Factors like hair color and individual hair growth differences can influence drug metabolite levels in hair.

Note: Although commonly called "hair follicle tests", the test actually examines the hair strand, not the follicle beneath the skin.

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.
