Hair Follicle Drug Testing - Stiles, PA

What it is, How it works

Hair analysis has become recognized as an effective method for identifying drug and alcohol consumption. Hair offers a comprehensive timeline of substance use by encapsulating biomarkers within the strands as they grow. When taken from the scalp, hair testing can reveal up to an estimated 90-day history of alcohol and drug use. Collecting hair is straightforward, moderately challenging to tamper with, and convenient to transport.

An optimal testing sample includes a 1.5-inch length of approximately 200 hair strands (comparable to the width of a pencil), yielding 100mg of hair, suitable for both screening and confirmation tests. For EtG, additional tests, and/or panels exceeding 10, 150mg is preferred. It’s advisable to measure the sample with a jeweler’s scale. If scalp hair is not available, a similar quantity of body hair could be used. In this context, head hair refers specifically to scalp hair, while body hair includes all other forms (facial, axillary, etc.).

Process Overview

The drug testing procedure in the laboratory comprises four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning deals with the preliminary handling of a sample in a lab’s framework. This process ensures the sample is sealed and transported correctly, assigns it a unique LAN (Laboratory Accessioning Number), and completes necessary data entry absent in an electronic chain of custody setup.

Screening is a rapid assessment for detecting abuse of drugs. Although cost-efficient to rule out drug presence in most samples, any positive screen must be verified for legal suitability. Samples showing positive results in Screening necessitate further confirmation.

In cases where Screening indicates a positive result, additional hair is extracted from the initial sample and processed for Extraction. During this phase, drugs are isolated from hair at a much lower concentration compared to other methods (e.g., urine or oral fluid), which makes hair drug testing particularly challenging to execute.

Any positive Screening results undergo Confirmation through GC/MS, GC/MS/MS or LC/MS/MS. Prior to Confirmation, all positive samples are washed if required. From Accessioning to Confirmation, the entire laboratory workflow is scrutinized under both the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can identify drug use for up to 90 days, unlike urine tests that have a more limited timeframe.
• Challenging to manipulate: Hair drug tests are tough to alter, ensuring greater reliability in the results.
• Records historical data: It offers insight into a pattern of drug use over time rather than just recent consumption.

Limitations:

• Inability to detect new use: It typically takes 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug tests tend to be costlier than other drug detection methods.
• Result variances: Elements like hair color and personal hair growth differences can impact drug metabolite levels in hair.

Note: Often termed "hair follicle tests", the test itself evaluates the hair strand and 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.
