Hair Follicle Drug Testing - Tolono, IL

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair strands retain a comprehensive record of alcohol and drug use by capturing biomarkers within the hair as it grows. When sampled near the scalp, hair can offer up to a three-month detection period for alcohol and drugs. Hair is easy to collect, challenging to tamper with, and uncomplicated to transport.

A 1.5-inch strand collection, roughly 200 strands of hair (the size of a #2 pencil) near the scalp, yields 100mg of hair, the perfect sample for testing and verification. For EtG, enhancements, and tests exceeding 10 panels, 150mg of the sample is suggested. It's advisable to measure the specimen with a jeweler’s scale. If scalp hair cannot be obtained, an equivalent amount of body hair is acceptable. When mentioning head hair, it specifically refers to scalp hair, whereas body hair encompasses other hair types (such as facial and axillary).

Process Overview

The laboratory progression of processing a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to initially incorporating a sample into the laboratory’s system. This step ensures the sample was properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and finalizes any missing data entry absent from an electronic chain of custody system.

Screening offers a preliminary and efficient method for detecting drugs of abuse. Although Screening is an economical approach to exclude drug use for most samples, a positive result from screening requires validation to hold up in legal proceedings. Any samples preliminarily positive in Screening necessitate secondary confirmation.

When a sample tests presumptively positive during Screening, additional hair is retrieved from the original sample for Extraction. This phase extracts drugs from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), making hair drug screening a challenging practice to conduct.

The validation of any positive screening result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation if necessary. The comprehensive laboratory sequence from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and the compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use over as long as 90 days, whereas urine tests offer a narrower timeframe.
• Challenge to manipulate: It's quite difficult to undermine a hair drug test, enhancing the reliability of results.
• Records historical use: Provides a drug usage pattern over time, beyond just recent consumption.

Limitations:

• Cannot detect recent consumption: Drugs become detectable in hair after about 5-7 days.
• Expense: Hair drug tests typically cost more than other drug tests.
• Result variance: Elements like hair color and individual growth differences can influence drug metabolite levels in hair.

Note: Though commonly termed as "hair follicle tests", the analysis targets the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Tolono, IL, hair follicle testing holds a significant edge over urine tests due to its superior detection abilities. While urine tests serve as common practice, they often miss longer-term use.

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.
