Hair Follicle Drug Testing - Pleasant Hill, IA

What it is, How it works

Hair analysis has emerged as an effective instrument for detecting drug and alcohol consumption. Hair captures a comprehensive history of substance use by preserving biomarkers within the fibers of the growing hair. When gathered near the scalp, hair offers an approximate 3-month detection period for drugs and alcohol. Collection is straightforward, tampering is challenging, and shipping is convenient.

A 1.5-inch segment of around 200 hair strands (comparable to a #2 pencil) near the scalp yields 100mg of hair, the prime sample for both screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, 150mg of hair sample is suggested. We advise weighing the sample with a jeweler's scale. If scalp hair is inaccessible, an equivalent amount of body hair can be used. "Head hair" strictly pertains to scalp hair, while "body hair" includes all other types (facial, axillary, etc.).

Process Overview

The key stages in laboratory processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails incorporating a sample into a lab’s system. Ensuring the sample's proper sealing and shipping, assigning a random Laboratory Accessioning Number (LAN), and filling in any missing information not supplied by an electronic chain of custody system are part of this process.

Screening involves an expedited initial test for drug abuse. While Screening is an economical approach to dismiss drug use in most samples, a positive screen requires confirmation for court validity. Presumptive positives in Screening demand subsequent confirmation.

For samples presumptively positive in Screening, additional hair is extracted from the primary specimen to undergo Extraction. During this stage, drugs are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.

Positive screening confirmations are executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing prior to confirmation, if necessary. The entire laboratory process from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair designation standards and accreditation to ISO / IEC 17025.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for as much as 90 days, whereas urine tests have a briefer detection period.
• Minimized possibility of cheating: Cheating on a hair drug test is extremely challenging, ensuring greater accuracy of results.
• Historical trend information: It reveals a pattern of substance use over a duration, rather than merely recent activity.

Limitations:

• Inability to detect recent use: It generally takes 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests tend to be costlier than other drug testing techniques.
• Result variability: Factors like hair color and individual growth differences may affect drug metabolite concentration in hair.

Note: Although commonly called "hair follicle tests," the evaluation targets the hair strand, 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.
