Hair Follicle Drug Testing - Kilbourne, LA

What it is, How it works

Hair analysis has become recognized as an effective means for detecting drug and alcohol consumption. Hair offers an extended timeline of alcohol and drug usage by embedding biomarkers within the fibers of the developing hair shaft. When sampled adjacent to the scalp, hair can offer up to roughly a 3-month detection duration for alcohol and various drugs. The collection process for hair is straightforward, manipulation is relatively challenging, and the shipping is uncomplicated.

A specimen of 1.5 inches comprising around 200 hairs (akin to the thickness of a #2 pencil), closest to the scalp, yields about 100mg of hair, the optimum amount for both screening and confirmation. For EtG enhancements and/or tests with panels exceeding 10, a 150mg sample is advised. We suggest utilizing a jeweler’s scale to weigh the sample. Should scalp hair be inaccessible, an equivalent volume of body hair can be utilized. In the context of head hair, we refer solely to scalp hair. Body hair encompasses all other types of hair (such as facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result encompasses four principal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the preliminary handling of a sample into a laboratory’s framework. This phase ensures that the sample was correctly sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any supplementary data input absent from an electronic chain of custody system.

Screening features an initial rapid evaluation for unlawful substances. While Screening offers a budget-friendly approach to exclude drug consumption in the bulk of samples, a positive outcome necessitates confirmation to be viable in legal proceedings. Any samples tentatively identified as positive during Screening require further confirmation.

Should a sample return a tentative positive result in the Screening stage, additional hair is extracted from the original sample and prepped for Extraction. Here, drugs are isolated from hair at significantly reduced concentrations compared to other procedures (such as urine or oral fluids), making hair drug screening the most complex approach to execute.

Verification of any positive screening outcome is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation, as deemed necessary. The complete laboratory procedure, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair specification and the compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeline: Hair drug tests can identify drug consumption for as long as 90 days, unlike urine tests which have a briefer detection timeline.
• Challenges in falsification: It is highly challenging to alter a hair drug test, ensuring greater accuracy in outcomes.
• Historical data provision: The test can outline a pattern of drug consumption over a certain period, not simply recent usage.

Limitations:

• Inability to detect recent consumption: Drugs require about 5-7 days to become detectable in hair.
• Expense: Hair drug tests are typically costlier relative to other drug testing methods.
• Variability in outcomes: Individual factors such as hair color and growth rate might influence drug metabolite concentrations in hair.

Note: Despite frequently being labeled as "hair follicle tests", the actual analysis focuses on the hair shaft rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why do hair follicle tests outshine urine tests in Kilbourne, LA? The answer lies in their superior detection accuracy and reliability. While urine tests identify recent drug use, hair testing provides a comprehensive history, making it a more comprehensive method for evaluating substance use.

Extended Detection Window

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.
