Hair Follicle Drug Testing - Mcgregor, FL

What it is, How it works

Hair analysis has gained recognition as an effective means for identifying drug and alcohol consumption. The hair captures a comprehensive timeline of alcohol and drug intake by embedding biomarkers within its fibers as it grows. By obtaining samples near the scalp, hair can reveal alcohol and drug use over about a 90-day period. This method is straightforward for collection, challenging to tamper with, and convenient to transport.

A hair sample measuring 1.5 inches, consisting of roughly 200 strands (similar to the thickness of a #2 pencil) closest to the scalp, delivers 100mg of hair, which is optimal for both screening and verification. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg specimen is advised. It's advisable to verify the specimen's weight using a jeweler’s scale. If scalp hair isn't available, a comparable amount of body hair can be used. When referring to head hair, it specifically means scalp hair. Body hair pertains to all other types of hair (e.g., facial, underarm, etc.).

Process Overview

The laboratory process for a drug test result consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning integrates the sample into the lab's system. This phase ensures the sample was properly sealed and transported, assigns it a unique LAN (Laboratory Accessioning Number), and completes any supplementary data entry not captured via an electronic chain of custody system.

Screening offers a preliminary check for substances of abuse. Though a cost-efficient measure for excluding drug consumption in most samples, a supportive screen must be validated for legal proceedings. Any samples testing positive in Screening necessitate additional verification.

For samples with a presumptive positive result in Screening, extra hair from the initial specimen is prepared for Extraction. This involves extracting drugs from hair at significantly reduced concentrations compared to other methods (e.g., urine or oral fluids), making hair analysis the most challenging form to conduct.

Confirmation for any positive screening is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before verification if needed. The complete lab workflow, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair standard and adheres to ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug analyses can reveal drug consumption for up to 90 days, while urine analyses offer a reduced detection span.
• Difficult to falsify: It's notably challenging to manipulate a hair drug test, thus ensuring more reliable results.
• Offers historical insight: This method can identify patterns of drug use over time and not just recent consumption.

Limitations:

• Inability to detect recent consumption: Drugs only become detectable in hair after approximately 5-7 days.
• Expense: Hair drug analyses typically incur higher costs than alternative drug testing approaches.
• Result variations: Factors like hair color and individual hair growth rates can influence drug metabolite concentrations in hair.

Note: Although frequently termed "hair follicle tests", the analysis actually examines the hair strand and not the follicle beneath the skin.

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.
