Hair Follicle Drug Testing - Chester, VT

What it is, How it works

Recognized as a compelling method for detecting drug and alcohol consumption, hair testing offers a long-term record by encapsulating biomarkers within the strands of hair as it grows. If garnered close to the scalp, hair can reveal a detection window of nearly three months for both alcohol and drugs. The collection process of hair is straightforward, challenging to tamper with, and convenient to ship.

A 1.5-inch section containing roughly 200 hair strands, akin to the width of a #2 pencil, nearest to the scalp supplies 100mg of hair, which is the perfect sample size for screening and verification. For EtG, additional tests, and/or those exceeding 10 panels, 150mg of the sample is advised. It is suggested to weigh the sample using a jeweler's scale. Should scalp hair be unavailable, an equivalent amount of body hair may be used. "Head hair" denotes scalp hair exclusively, whereas "body hair" encompasses all other forms like facial and axillary hair.

Process Overview

The laboratory procedure for drug test results encompasses four essential steps: Accessioning, Screening, Extraction, and Confirmation.

Within Accessioning, there is an initial process where a sample is integrated into the laboratory's system. This phase ensures the sample’s proper sealing and shipment, assigns an arbitrary LAN (Laboratory Accessioning Number), and performs additional data entry when not handled by an electronic chain of custody system.

In the Screening phase, an expedient initial assessment for drugs of abuse is conducted. While Screening is a cost-efficient strategy to eliminate drug use on most samples, a positive screen mandates confirmation to hold up in court. All samples that test presumptively positive in Screening necessitate follow-up confirmation.

Presumptively positive samples from the Screening must undergo further processing in the Extraction stage, where additional hair is extracted from the initial sample. This stage involves extracting drugs from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which renders hair drug screening a highly challenging process.

For Confirmation, positive screening results are validated through GC/MS, GC/MS/MS, or LC/MS/MS. Before Confirmation, all presumptive positive specimens are washed as needed. The entire laboratory workflow, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests can highlight drug usage for up to 90 days as opposed to urine tests which have a shorter detection window.
• Increased difficulty to manipulate: Cheating a hair drug test is considerably difficult, enhancing result precision.
• Offers historical insight: This test can delineate a drug use pattern over a duration, instead of merely indicating recent use.

Limitations:

• Inability to detect recent consumption: Drugs become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug tests typically incur a higher cost compared to other testing methods.
• Result variations: Factors like hair color and personal differences in hair growth can influence the drug metabolite concentration in hair.

Note: Although commonly termed "hair follicle tests", the test scrutinizes the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Chester, VT, hair follicle testing stands out when compared to traditional urine tests. Its superior detection capability offers unmatched accuracy and reliability.

The advantage of hair testing lies in its ability to detect a broader spectrum of drug use. This makes it a more comprehensive solution over urine tests for effective substance assessment.

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.
