Hair Follicle Drug Testing - Westphalia, IA

What it is, How it works

Hair testing is recognized as an effective method for uncovering drug and alcohol consumption. Hair provides an extended-term record of substances by capturing biomarkers within the hair's fibers as it grows. When obtained from near the scalp, hair can offer a detection period of up to around three months for substances. Hair collection is straightforward, somewhat resistant to tampering, and simple to transport.

A 1.5-inch segment consisting of roughly 200 hair strands (similar in size to a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal sample size for testing and validation. For EtG checks, additional substances, and tests extending beyond ten panels, a sample of 150mg is advised. Use a jeweler’s scale for measuring the specimen. In the absence of scalp hair, a similar amount of body hair may be gathered. The term "head hair" exclusively denotes scalp hair. "Body hair" encompasses all other hair types (facial, axillary, etc.).

Process Summary

The primary phases in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the initial handling of a sample within a lab's database. This process verifies proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any necessary data input not covered by an electronic chain of custody system.

Screening is an initial rapid assessment for substance abuse. Screening is cost-effective for excluding drug use in most samples; however, a positive screen necessitates further confirmation for legal acceptance. Samples that test as potentially positive in Screening require an additional review.

Should a sample be potentially positive during Screening, additional hair is extracted from the initial sample and prepared for Extraction. Here, substances are withdrawn from hair at considerably lower concentrations than other methods (such as urine or oral fluids), which contributes to hair drug screening's high level of difficulty.

Confirmation of a positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing potentially positive are cleansed before confirmation as necessary. The complete laboratory process from Accessioning to Confirmation undergoes evaluation as per the guidelines of the CAP (College of American Pathologists) Hair classification and complies with ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection period: Hair drug assessments identify drug use for as long as 90 days, unlike urine tests with shorter detection spans.
• Challenging to manipulate: Hair drug testing is hard to deceive, enhancing result accuracy.
• Chronological insights: It offers a depiction of substance use over time, rather than immediate usage.

Drawbacks:

• Inability to identify recent use: Substances become detectable in hair roughly 5-7 days after use.
• Expense: Hair drug assessments typically incur higher costs than alternative testing techniques.
• Result variability: Attributes like hair color and individual hair growth disparity can affect drug metabolite levels in hair samples.

Note: Though frequently called "hair follicle tests", this test 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.
