Hair Follicle Drug Testing - Silver Hill, MD

What it is, How it works

Hair analysis has emerged as a significant method for identifying drug and alcohol consumption. Within the hair structure, long-term traces of alcohol and other drugs are held by capturing markers within the strands as they grow. When hair is cut near the scalp, it can reveal a detection span of up to around three months for substances like alcohol and drugs. Collecting hair is straightforward, not easy to tamper with, and can be shipped without hassle.

A sample measuring 1.5 inches with about 200 hair strands (similar in size to a #2 pencil) gathered nearest to the scalp provides 100mg of hair, which is optimal for both screening and confirmation. For EtG, enhancements, or tests exceeding 10 panels, a collection of 150mg is advised. Using a jeweler’s scale is recommended for weighing the sample. In the absence of scalp hair, a similar quantity of body hair may be obtained. Reference to head hair exclusively pertains to scalp hair. Body hair encompasses all remaining hair types (facial, axillary, etc.).

Process Overview

The laboratory handling of a drug test outcome involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning deals with the initial intake of a sample into the lab's system. This step includes ensuring the sample's seal and secure shipping, designating a random LAN (Laboratory Accessioning Number), and completing additional data entries not accounted for by an electronic custody trail.

Screening constitutes a preliminary rapid analysis for potential drug abuse. While Screening serves as a budget-friendly approach to rule out drug presence in most samples, a confirmed positive result is essential for legal proceedings. Any samples flagged as likely positive in Screening mandate further confirmation.

When a sample returns presumptively positive from Screening, additional hair from the original sample is collected and prepped for Extraction. During this phase, drugs are extracted from hair at substantially lower concentrations than via other methods (e.g., urine or oral fluid), underscoring why hair drug testing poses the highest challenge in methodology.

Confirmation of any positive screen is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Necessary washing precedes confirmation for any presumptive positive samples. The entire lab process, from Accessioning to Confirmation, is reviewed in accordance with the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection timeline: Hair drug screenings can trace drug use for as long as 90 days, whereas urine tests offer a shorter detection range.
• Difficulty to tamper: Hair drug tests are tough to cheat, rendering the findings more reliable.
• Gives historical perspective: These tests can outline patterns of drug consumption over a timeline, not just immediate use.

Limitations:

• Cannot detect recent use: It takes roughly 5-7 days for drugs to manifest in hair samples.
• Expense: Hair drug analyses are often pricier compared to other testing methods.
• Result variations: Elements like hair color and personal hair growth differences may impact the drug metabolite levels in hair.

Note: Despite being commonly named "hair follicle tests", the examination actually assesses the hair strand instead of 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.
