Hair Follicle Drug Testing - Winnie, TX

What it is, How it works

Hair analysis is regarded as an effective method for identifying drug and alcohol consumption. Hair offers a comprehensive timeline of alcohol and drug usage by embedding biomarkers within the strands as they grow. When obtained near the scalp, hair can reveal a detection period of up to three months for alcohol and drugs. Hair collection is straightforward, relatively tamper-proof, and easily transportable.

A 1.5-inch section comprising roughly 200 strands of hair (comparable in size to a #2 pencil) pulled from the nearest point to the scalp yields 100mg of hair, which is the optimal quantity for both screening and confirmation. For EtG, additional substances, and tests exceeding 10 panels, a 150mg sample is preferable. It is advisable to measure the sample using a jeweler’s scale. If scalp hair is not an option, a similar volume of body hair can be utilized. "Head hair" refers specifically to scalp hair, while "body hair" encompasses all other types, such as facial or underarm hair.

Process Overview

The laboratory processing workflow for drug test results involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase where a sample is integrated into a laboratory's system. This includes ensuring the sample's seal and shipment are intact, generating an arbitrary LAN (Laboratory Accessioning Number), and completing any extra data documentation not captured by an electronic chain of custody protocol.

Screening serves as a preliminary evaluation for identifying drug abuse. While it is an economical approach to dismiss drug use in most samples, any positive screening requires confirmation to be valid in legal proceedings. Samples that show a potential positive result during Screening necessitate additional confirmation.

For samples showing potential drug presence after Screening, additional hair from the original sample is used for the Extraction phase. Here, drugs are isolated from hair at concentrations lower than other methods (e.g., urine or oral fluids), underscoring the complexity of hair drug analysis.

Verification of a positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Prior to confirmation, all samples presumed positive are cleaned as needed. The complete laboratory sequence from Accessioning to Confirmation is assessed under both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can identify drug use for as long as 90 days, whereas urine tests have a much shorter detection period.
• Immunity to cheating: Hair drug assessments are highly resistant to cheating, ensuring more dependable results.
• Tracks drug use history: These tests can reveal patterns of drug use over time, rather than just recent consumption.

Limitations:

• Inability to detect recent use: Drugs typically become detectable in hair after 5-7 days.
• Expense: Hair drug testing tends to be costlier than alternative drug testing methods.
• Result variance: Elements such as hair color and personal hair growth variations can influence drug metabolite levels within hair.

Note: The term "hair follicle tests" often used is misleading, as the analysis focuses on 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.
