Hair Follicle Drug Testing - Whaleyville, MD

What it is, How it works

Viewed as a crucial resource, hair testing is instrumental in detecting drug and alcohol consumption. It captures a long-term record of substance use by embedding biomarkers within the growing hair's fibers. When obtained close to the scalp, hair can reveal a substances use timeline spanning up to roughly 90 days. This method is straightforward to collect, relatively tamper-resistant, and easy to transport.

A 1.5-inch section consisting of approximately 200 hair strands (comparable to the diameter of a #2 pencil) from the scalp region yields 100mg, the optimal sample size for both screening and confirmation. For tests such as EtG, add-ons, or those exceeding 10 panels, 150mg of hair is advised. Using a jeweler’s scale to weigh the sample is recommended. Should scalp hair be lacking, an equivalent quantity of body hair can be harvested. The term 'head hair' is specifically used to denote scalp hair, whereas 'body hair' pertains to other types (e.g., facial, axillary, etc.).

Process Overview

The key stages in the lab processing sequence for a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary phase where a sample is processed into the lab's system. This process ensures the sample's seal and shipping integrity, assigns it a random Laboratory Accessioning Number (LAN), and performs any additional data entry tasks not covered by an electronic chain of custody system.

Screening is the initial swift examination for substances of abuse. Though screening efficiently eliminates drug use concerns for most samples, any positive screening result necessitates confirmation to be legally valid. Samples presumed positive during Screening must undergo further confirmation.

Upon presumptive positivity in the Screening phase, additional hair is extracted from the primary sample and readied for the Extraction phase. Here, drugs are extracted from the hair at concentrations much lower than in alternative methods (i.e., urine or oral fluid), underscoring the complexity of performing hair drug analysis.

Confirmation of positive screening outcomes utilizes GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation where needed. The complete lab process, spanning Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests identify drug use up to 90 days, surpassing the shorter detection periods of urine tests.
• Hard to falsify results: Hair drug tests are challenging to cheat, which contributes to greater result reliability.
• Historical consumption data: It reveals drug consumption trends over a timeframe, beyond just momentary use.

Limitations:

• Inability to detect recent consumption: A time frame of about 5-7 days is needed for drugs to be traceable in hair.
• Expense: Hair drug tests tend to be more costly than other drug testing strategies.
• Result variations: Factors like hair color and personal hair growth differences can influence drug metabolite levels in hair.

Note: Although frequently termed as "hair follicle tests", the analysis targets the hair strand rather than 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.
