Hair Follicle Drug Testing - Lake Beulah, WI

What it is, How it works

The utilization of hair testing has become recognized as an effective means for identifying the use of drugs and alcohol. Hair captures a prolonged timeline of alcohol and drug usage by embedding biomarkers within the fibers of the developing hair shaft. When acquired near the scalp, hair can offer an approximate 3-month detection window for both alcohol and drugs. Hair collection is uncomplicated, relatively tamper-proof, and straightforward to transport.

A sample measuring 1.5 inches consisting of around 200 hair strands (roughly the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal amount for testing and validation. For EtG, supplementary tests, and/or screenings exceeding 10 panels, a sample of 150mg is advised. It is suggested to measure the sample on a jeweler’s scale. Should scalp hair be unavailable, an equivalent quantity of body hair can be used. When discussing head hair, it specifically refers to scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result primarily involves four stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially processed into the laboratory’s system. This step includes ensuring the sample was correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any outstanding data entry not accounted for by an electronic chain of custody system.

The Screening phase involves a preliminary rapid check for drugs of abuse. While it is a cost-efficient way to eliminate drug usage in the majority of samples, a positive screening result requires confirmation to be permissible in legal contexts. Samples with presumptive positive results in Screening necessitate further validation.

If Screening indicates a presumptive positive, additional hair is extracted from the original sample and prepared for Extraction. This process involves extracting drugs at significantly lower concentrations from hair compared to other methods (such as urine or oral fluid), which is why hair drug testing is among the most challenging methodologies.

Confirmation of any positive result detected in Screening is conducted using GC/MS, GC/MS/MS, or LC/MS/MS technologies. All samples presumed positive are cleansed before Confirmation as necessary. The complete process from Accessioning to Confirmation is examined 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 significantly shorter detection span.
• Challenging to manipulate: It is extremely difficult to deceive a hair drug test, thereby enhancing the reliability of the results.
• Offers historical context: It enables the identification of drug consumption patterns over time, not merely recent usage.

Limitations:

• Inability to detect recent usage: It requires roughly 5-7 days for drugs to become evident in hair.
• Expensive: Hair drug tests generally incur higher costs compared to alternative drug testing methods.
• Result variability: Influences such as hair color and personal variations in hair growth can influence drug metabolite concentrations in hair.

Note: Although commonly called "hair follicle tests", the examination focuses on 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.
