Hair Follicle Drug Testing - Eau Claire, PA

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures a comprehensive history of alcohol and other substances by embedding biomarkers in the strands as they grow. When collected near the scalp, hair offers an approximate 3-month detection timeframe for alcohol and other substances. It is straightforward to collect, challenging to tamper with, and simple to transport.

A 1.5-inch hair sample consisting of roughly 200 strands (around the diameter of a #2 pencil) nearest the scalp will yield 100mg of hair, which is the optimal quantity for screening and confirmation. For EtG, supplements, and/or panels surpassing 10, a 150mg sample is advised. We suggest measuring the sample's weight with a jeweler’s scale. In the event that scalp hair is not available, an equivalent volume of body hair can be used. When we mention head hair, we refer exclusively to scalp hair. Body hair refers to any other hair types (such as facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test involves four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the preliminary processing of a sample into a lab's system. This step ensures the sample was properly sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data entry not covered by an electronic chain of custody system.

Screening conducts an initial swift assessment for illicit substances. Screening is an economically sensible approach to dismiss drug presence in the majority of samples; however, a positive result from screening must be verified to be legally accepted. Any samples that show a presumptive positive during Screening require further confirmation.

If a sample shows a presumptive positive during the Screening phase, additional hair is extracted from the initial sample and processed for Extraction. In this stage, substances are isolated from hair at lower concentrations than those in other samples (e.g., urine or oral fluid), which explains why hair drug screening is the most challenging method to execute.

Confirmation of a positive screening output is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. The comprehensive laboratory process, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair definition and the certification to ISO / IEC 17025 benchmarks.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can trace drug use for up to 90 days, while urine tests have a more restricted detection range.
• Resistance to manipulation: It is very challenging to manipulate a hair drug test, ensuring more precise results.
• Historical data provision: It offers a record of drug usage over a duration, not merely recent ingestion.

Limitations:

• Inability to recognize recent use: It requires approximately 5-7 days for substances to manifest in hair.
• Expense: Hair drug tests generally incur higher costs than alternative testing methods.
• Result variability: Variables like hair pigmentation and individual hair growth disparities might impact drug metabolite levels in hair.

Note: Although often termed "hair follicle tests", the analysis assesses the hair shaft and not the underlying follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Eau Claire, PA, offers significantly better accuracy and reliability compared to urine tests. While urine tests detect recent drug use, hair tests cover up to 90 days. This extended detection period makes hair testing more comprehensive and less prone to manipulation, ensuring consistent and trustworthy results.

Extended Detection Window

The extended detection window of hair follicle testing is a standout feature in Eau Claire, PA. Covering a span of up to 90 days, these tests give employers a thorough insight into an individual's drug use history, allowing for informed decisions about hiring and ongoing employee evaluations.

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.
