Hair Follicle Drug Testing - Columbus City, IA

What it is, How it works

Hair analysis is regarded as a potent method for spotting drug and alcohol consumption. Hair archives a prolonged history of alcohol and drug intake by encasing biomarkers within the hair strand's growing fibers. Collected near the scalp, hair can offer roughly a 3-month detection span for alcohol and other substances. Hair is straightforward to collect, relatively immune to tampering, and simple to transport.

A 1.5-inch segment of around 200 hair strands (approximately the thickness of a #2 pencil) near the scalp yields 100mg, the optimal sample for both preliminary and detailed examination. For EtG, supplementary tests, or examinations exceeding 10 panels, 150mg of the sample is advisable. We suggest measuring the specimen with a jeweler’s scale. If scalp hair is not available, a similar quantity of body hair may be gathered. "Head hair" pertains solely to scalp hair, while "body hair" includes all other hair varieties (facial, axillary, etc.).

Process Overview

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

Accessioning entails the initial handling of a sample into a lab’s system, ensuring the sample was properly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing additional data that an electronic chain of custody system might not provide.

Screening features an initial rapid test for drug abuse. Although Screening is a cost-effective method to eliminate drug use on most samples, a positive screen requires confirmation for court admissibility. Any samples initially testing positive in Screening need further confirmation.

If a sample is initially positive during Screening, more hair is extracted from the original specimen for Extraction preparation. In this phase, drugs are withdrawn from hair at a much lower concentration than in other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to conduct.

Confirmation of any positively screened result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All initially positive samples undergo washing before confirmation if necessary. The complete laboratory procedure from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair tests identify drug use up to 90 days, unlike urine tests with a shorter window.
• Hard to falsify: Hair drug tests are tough to compromise, enhancing result accuracy.
• Offers historical insights: It displays a timeline of drug use over time, not just recent consumption.

Limitations:

• Cannot identify recent use: Drugs become traceable in hair after approximately 5-7 days.
• Expense: Hair drug tests typically incur higher costs than other testing methodologies.
• Result variability: Various elements like hair color and personal hair growth differences may impact drug metabolite levels in hair.

Note: Frequently termed as "hair follicle tests," the examination is on the hair strand rather than 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.
