Hair Follicle Drug Testing - Madisonville, TN

What it is, How it works

Hair analysis has emerged as a significant method for uncovering substance and alcohol consumption. Hair captures a prolonged record of alcohol and drug use by embedding biomarkers in the strands of developing hair. When hair is clipped close to the scalp, it can offer up to a 90-day detection timeline for alcohol and various drugs. The collection of hair is straightforward, relatively resistant to tampering, and easy to transport.

A sample measuring 1.5 inches with roughly 200 hair strands (around the width of a #2 pencil) taken nearest to the scalp yields 100mg, which is the preferred amount for both preliminary and confirmatory testing. For EtG, additional tests, or tests exceeding 10 panels, 150mg is advisable. It is suggested to measure the sample with a jeweler’s scale. If head hair is not available, an equivalent volume of body hair may be used. Head hair refers specifically to scalp hair. Body hair encompasses all other varieties of hair (facial, axillary, etc.).

Process Overview

There are four primary stages in the lab evaluation of a drug test sample: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the preliminary handling of a sample in a lab’s system. This process entails ensuring that the sample was correctly sealed and transported, assigning it a random LAN (Laboratory Accessioning Number), and carrying out any extra data entry not included by an electronic chain of custody system.

Screening provides an initial rapid assessment for drugs of abuse. Though Screening is an economical means to dismiss drug use in most samples, a positive Screen must be verified to be court-admissible. Samples that are presumptively positive during Screening require further confirmation.

Should a sample show presumptive positivity in Screening, more hair is extracted from the original sample for Extraction. During Extraction, drugs are isolated from hair at concentrations lower than those achievable with other methods (e.g., urine or oral fluid), rendering hair drug testing one of the most challenging methodologies to conduct.

Any positive Screening outcomes are validated through GC/MS, GC/MS/MS, or LC/MS/MS. All suspected positive samples undergo washing before Confirmation if necessary. The complete lab procedure from Accessioning to Confirmation is scrutinized under both the guidelines of the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Benefits of hair drug analysis:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, whereas urine tests have a more limited detection time.
• Tamper resistance: It is extremely difficult to deceive a hair drug test, resulting in more dependable outcomes.
• Historical usage insight: It provides an overview of drug consumption patterns over time, not just recent usage.

Drawbacks:

• Inability to detect recent use: It requires 5-7 days before drugs become detectable in hair.
• Expense: Hair drug tests are typically pricier than other testing approaches.
• Result variability: Elements like hair pigment and individual hair growth differences can influence drug metabolite levels in hair.

Note: While often termed "hair follicle tests", the analysis actually examines 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.
