Hair Follicle Drug Testing - Mcfarland, WI

What it is, How it works

Hair testing has gained recognition as an effective tool for identifying drug and alcohol use. Hair provides an extended-lasting history of alcohol and other drugs by capturing biomarkers in the strands' fibers as hair grows. When taken close to the scalp, hair can reveal a nearly 3-month timeframe for detecting alcohol and other drugs. Hair is straightforward to obtain, relatively challenging to tamper with, and convenient to transport.

A 1.5-inch sample consisting of about 200 hairs (roughly the size of a #2 pencil) near the scalp will yield 100mg of hair, the optimal amount for both screening and confirmation processes. For EtG, additional tests, and/or panels exceeding 10, a specimen of 150mg is advisable. Using a jeweler’s scale to weigh the specimen is recommended. If scalp hair isn't available, an equivalent amount of body hair can be used. When discussing head hair, we mean scalp hair exclusively. Body hair pertains to all other hair types (facial, axillary, etc.).

Process Overview

The four essential steps in laboratory drug test processing include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step where a sample is integrated into a lab’s system. It involves verifying the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data not given by an electronic chain of custody system.

Screening involves a preliminary swift check for substances of abuse. While Screening offers a cost-effective means to dismiss drug use in most samples, a positive result requires confirmation to be admissible in court. Any samples with a presumptive positive in Screening require secondary confirmation.

If a sample shows a presumptive positive result in Screening, more hair is extracted from the initial specimen and prepared for Extraction. At this stage, drugs are extracted from hair at a significantly lower concentration than in other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.

Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, any presumptive positive samples are washed as necessary. The complete laboratory process from Accessioning to Confirmation undergoes review 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 window: Hair drug tests can trace drug use for up to 90 days, whereas urine tests have a shorter timeframe.
• Hard to manipulate: Hair drug tests are significantly challenging to manipulate, ensuring more accurate results.
• Offers historical insights: It provides a pattern of drug use over time, not just recent usage.

Limitations:

• Cannot identify recent consumption: Drugs become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug tests typically incur higher costs compared to other testing methods.
• Result variability: Elements such as hair color and individual growth differences can impact drug metabolite concentration in hair.

Note: Though often termed "hair follicle tests," the test analyzes the hair strand, not the hair 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.
