Hair Follicle Drug Testing - Rhine, WI

What it is, How it works

Utilizing hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair provides an extended overview of alcohol and other substances due to biomarkers being encased within the hair strand as it grows. When taken near the scalp, hair offers up to a roughly 90-day detection period for identifying substances. Hair collection is straightforward, tough to tamper with, and convenient to transport.

A 1.5-inch section comprising approximately 200 hair strands (equivalent to a #2 pencil) closest to the scalp yields 100mg, which is the optimal amount for analysis and verification. For EtG and extended panels beyond 10, a sample weighing 150mg is advised. We suggest measuring the hair sample using a jeweler’s scale. If scalp hair is inaccessible, an equivalent section of body hair can be obtained. When we mention head hair, it pertains specifically to scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).

Process Overview

The laboratory's processing of a drug test result comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the first step of introducing a sample into a lab’s process. This phase ensures the sample's proper sealing and shipping, assigns it a random LAN (Laboratory Accessioning Number), and completes any missing data entry from a digital chain of custody.

Screening involves an expedited preliminary examination for substance misuse. While Screening is economical in ruling out drug consumption for most samples, a screened positive case must be verified for court usability. Any samples that test provisional positive in Screening require further confirmation.

For samples presumed positive in Screening, additional hair is taken from the original sample for Extraction. In this step, drugs are extracted from hair at notably lower concentrations than seen in other methods (e.g., urine or oral fluid), which is why hair drug testing is exceptionally challenging.

Confirming any positive screen is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with a presumption of positivity are cleaned before final confirmation as required. The laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug assessments can identify substance usage for up to 90 days, compared to the shorter detection in urine tests.
• Difficult to manipulate: Cheating on a hair drug test is significantly harder, enhancing result accuracy.
• Retrospective data: It provides a history of substance use over a timeline, rather than just recent instances.

Limitations:

• Incapable of detecting recent consumption: Drugs require around 5-7 days to become detectable in hair.
• Expense: Hair drug tests are typically pricier than alternative drug testing techniques.
• Result variations: Variability factors like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Even though often called "hair follicle tests", the analysis targets the hair strand, not the follicle under the skin.

Why Hair Follicle Testing Beats Urine Testing

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.
