Hair Follicle Drug Testing - Holts Summit, MO

What it is, How it works

Hair analysis is recognized as an effective means for detecting drug and alcohol consumption. By embedding biomarkers in the strands, hair offers a long-term record of alcohol and other substances. When obtained near the scalp, it can reveal usage over a span of roughly 90 days. Hair collection is straightforward, less prone to tampering, and easily transportable.

A sample measuring 1.5 inches and consisting of around 200 strands (comparable to the width of a #2 pencil) taken closest to the scalp amounts to 100mg, which is ideal for both screening and confirmation. For EtG, additional substances, and tests exceeding ten panels, a 150mg sample is advised. Utilizing a jeweler's scale is recommended for determining the specimen's weight. In the absence of scalp hair, a similar quantity of body hair can be used. When referencing head hair, it pertains solely to scalp hair, while body hair includes all other types (e.g., facial, axillary).

Process Overview

Drug testing in the lab involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the sample's preliminary integration into a lab's system. This process ensures the sample was sealed and transported correctly, assigns a unique Laboratory Accessioning Number (LAN), and finalizes any data not electronically available in the chain of custody.

Screening performs a preliminary assessment for drug presence. Although cost-efficient for ruling out drug use in most samples, a positive result necessitates confirmation for legal acceptance. Samples that test positive during screening require a secondary validation.

For samples that show a positive outcome in Screening, additional hair from the initial selection is prepared for Extraction. Here, drugs are isolated from hair at concentrations lower than in other test mediums (such as urine or oral fluid), underscoring the complexity of hair analysis.

Positive screening results undergo Confirmation through methods like GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are cleansed as needed. The full procedure, from Accessioning to Confirmation, is evaluated according to the CAP (College of American Pathologists) Hair designation and the 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 with shorter detection times.
• Hard to falsify: Given the difficulty of tampering with a hair test, the findings are more reliable.
• Offers historical insight: It helps in charting drug use patterns over time, beyond just recent intake.

Limitations:

• Delayed detection: Drugs become detectable in hair after about 5-7 days.
• Expense: Hair drug testing tends to cost more than alternative methods.
• Result variability: Factors like hair color and personal hair growth differences can impact drug metabolite concentrations in hair.

Note: Although termed "hair follicle tests," the test examines the strand itself 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.
