Hair Follicle Drug Testing - Vincent, IA

What it is, How it works

Hair testing has emerged as a significant method for identifying drug and alcohol consumption. Hair encapsulates a lengthy record of alcohol and drug usage by embedding biomarkers within the strands' fibers. When taken from near the scalp, hair can offer a detection timeframe of up to roughly three months for alcohol and narcotics. Hair is straightforward to collect, resistant to manipulation, and convenient to send.

An ideal hair sample, consisting of roughly 200 strands (comparable to the diameter of a #2 pencil) measuring 1.5 inches from the scalp, amounts to 100mg, perfect for screening and validation. For EtG, additional tests, and/or panels beyond ten, 150mg of the sample is advisable. We propose measuring the sample with a jeweler’s scale. If scalp hair is unavailable, a similar quantity of body hair can be used. "Head hair" refers solely to scalp hair, while "body hair" encompasses other hair categories (facial, axillary, etc.).

Process Overview

The four foundational stages in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the sample's integration into a laboratory's system, verifying proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing additional data entry not covered by an electronic chain of custody.

Screening comprises an initial, swift examination for drugs. Screening is a cost-efficient method to dismiss drug use in most samples; however, a positive screening result demands validation for legal presentation. Samples that show presumptive positivity in screening necessitate a follow-up confirmation.

In cases where a sample is provisionally positive during Screening, additional hair is extracted from the original sample and prepared for Extraction. This phase removes drugs from hair at significantly lower concentrations than other techniques (e.g., urine or oral fluid), making hair drug screening the most challenging method to perform.

The Confirmation of any positive screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation if needed. From Accessioning to Confirmation, the entire laboratory operation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, unlike urine tests which have a shorter detection timeframe.
• Hard to deceive: Cheating a hair drug test is notably challenging, ensuring more precise results.
• Yields historical insight: It can demonstrate a drug use pattern over a duration, rather than just reflecting recent consumption.

Limitations:

• Incapable of detecting recent use: Drugs become detectable in hair after about 5-7 days.
• Expense: Hair drug tests are typically pricier compared to other testing approaches.
• Result variability: Elements like hair color and personal hair growth differences might influence drug metabolite concentration in hair.

Note: Despite being often termed "hair follicle tests", the test itself examines the hair strand and not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

Why choose hair testing over urine? In Vincent, IA, hair follicle tests surpass when it comes to uncovering prior drug use with higher accuracy and reliability. They record substances ingested over a lengthy timeline, providing a clearer picture.

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.
