Hair Follicle Drug Testing - Minden, IA

What it is, How it works

Hair testing has emerged as a valuable resource in detecting substance use, both drug and alcohol-related. By embedding biomarkers within the fibres of hair that is actively growing, it effectively records past alcohol and drug intake. A segment of hair collected from near the scalp can reveal substance use patterns over approximately a 3-month interval. This method offers straightforward sample collection, is relatively tamper-resistant, and is easy to transport.

A 1.5-inch portion consisting of roughly 200 hair strands (akin to a #2 pencil thickness) near the scalp yields around 100mg of hair, which is the preferred quantity for both testing and confirmation. For EtG, extra panels, or where tests exceed 10 panels, a 150mg sample size is advised. Using a jeweler’s scale for specimen weight measurement is recommended. If scalp hair is absent, the equivalent quantity of body hair is usable. When discussing head hair, the reference is solely to scalp hair. All other hair types, including facial and axillary hair, fall under body hair.

Process Overview

Processing a drug test result in the lab involves four chief stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the specimen first enters the lab system. This phase verifies proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and fills in any required information not captured through an electronic chain of custody.

Screening serves as an initial, quick evaluation for substances of abuse. Despite being cost-efficient in ruling out drug use for the majority of samples, a positive screen must undergo confirmation to be legally permissible. Samples that are tentatively positive in Screening necessitate further confirmation.

Should a sample show presumptive positivity in Screening, additional hair is extracted from the primary specimen and prepared for Extraction. In this step, drugs are isolated from hair at significantly lower concentrations than seen in other techniques (e.g., urine or oral fluid), making hair drug screening a complex methodology to conduct.

Confirmation of any positive screening outcome utilizes GC/MS, GC/MS/MS, or LC/MS/MS. Samples indicating possible positivity undergo washing before confirmation when necessary. Every stage, from Accessioning to Confirmation, is evaluated under both CAP (College of American Pathologists) Hair designation and accreditation conforming to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can detect drug use up to 90 days, unlike urine tests which have a reduced detection window.
• Resistance to tampering: Hair drug tests are challenging to manipulate, leading to more trustworthy results.
• Chronological use pattern: It can establish a record of drug usage over an extended period, not merely recent consumption.

Limitations:

• Recent use detection: Detecting drugs in hair requires approximately 5-7 days post-use.
• Expense: Hair drug tests typically incur higher costs compared to other testing methods.
• Result variability: Variables like hair color and individual hair growth differences can influence drug metabolite concentration in hair.

Note: Although often termed "hair follicle tests", this testing process analyzes the hair strand rather than 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.
