Hair Follicle Drug Testing - Greenfield, IA

What it is, How it works

Recognized for their efficacy, hair tests are now valued as a potent mechanism for identifying the presence of substances like drugs and alcohol. Hair can encapsulate a prolonged timeline of substance intake by embedding biomarkers within the fiber of the hair as it grows. When a sample is taken near the scalp, it usually offers a detection period of up to three months for substances. Collecting hair samples is straightforward, challenging to tamper with, and convenient for transport.

A segment of hair measuring 1.5-inches, comprising roughly 200 strands (equivalent to the thickness of a #2 pencil) nearest to the head yields approximately 100mg, optimal for initial testing and verification. For measurements like EtG and screenings surpassing 10 panels, roughly 150mg is advisable. We suggest utilizing a jeweler’s scale for accurate weighing. In cases where scalp hair is not accessible, a similar quantity of body hair is acceptable. When referencing head hair, it pertains solely to scalp hair. Body hair encompasses other types (facial, axillary, etc.).

Process Overview

The process of laboratory drug result testing enfolds four primary stages: Accessioning, Screening, Extraction, and Confirmation.

In the course of Accessioning, samples are initially managed into the laboratory framework. This phase ensures the sample’s proper sealing and dispatch, assigns a unique LAN (Laboratory Accessioning Number), and completes any outstanding data entry omitted by electronic custody systems.

Screening provides a preliminary rapid assessment for detecting drug abuse. It serves as a budget-friendly method to dismiss drug usage in most cases, with any positive findings requiring further validation for legal proceedings. Presumptive positives discovered during Screening are subject to secondary affirmation.

Should a sample yield a presumptive positive during Screening, additional hair is extracted from the original sample for the Extraction phase. This involves extracting drugs from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), demonstrating why hair drug testing is notably challenging.

Confirmation of any detected positive results uses methodologies like GC/MS, GC/MS/MS, or LC/MS/MS. Every preliminary positive sample undergoes necessary washing before confirmation. The stepwise evaluation from Accessioning through to Confirmation observes both CAP (College of American Pathologists) guidelines for Hair testing and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Protracted detection span: Hair tests have the ability to identify drug consumption for up to 90 days, as opposed to urine tests which have a shorter range.
• Hard to falsify: Cheating a hair drug test is extremely challenging, bolstering the accuracy of results.
• Chronological drug use data: Offers insight into drug consumption patterns over an extended duration, not confined to recent use.

Limitations:

• Inability to detect recent usage: It requires 5-7 days for drugs to become evident in the hair.
• Expense: Hair drug tests generally incur higher costs compared to alternative testing approaches.
• Result variability: Elements like hair color and individual hair growth differences can influence the drug metabolite concentration within the hair.

Note: Commonly termed as "hair follicle tests", the analysis targets the hair strand, excluding 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.
