Hair Follicle Drug Testing - Crothersville, IN

What it is, How it works

Hair analysis is increasingly recognized as a potent method for detecting drug and alcohol usage. Hair captures a comprehensive history of alcohol and other substances by embedding biomarkers within the growing hair strand's fibers. When collected from near the scalp, hair can offer an approximate three-month detection timeframe for alcohol and other substances. The collection of hair is straightforward, relatively resistant to tampering, and convenient for transport.

A 1.5-inch section of approximately 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the preferred sample size for testing and verification. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the sample is suggested. We advocate weighing the sample on a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair can be collected. References to head hair specifically mean scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).

Process Overview

The process for laboratory analysis of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial incorporation of a sample into a lab's system. This involves checking that the sample was properly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing any further data input absent in a digital chain of custody system.

Screening comprises a preliminary rapid check for substance abuse. While Screening offers a cost-efficient method to exclude drug usage for the bulk of samples, a positive screen necessitates confirmation to be valid in a legal setting. All samples that are provisionally positive during Screening require a subsequent verification.

If a sample tests provisionally positive during Screening, additional hair is taken from the original sample and prepped for Extraction. During this step, drugs are extracted from hair at a significantly lower concentration than seen in other methods (e.g., urine or oral fluid), which is why hair drug screening is the most challenging method to execute.

Verification of any positive screening outcome is done through GC/MS, GC/MS/MS, or LC/MS/MS. Every provisionally positive sample is cleansed prior to verification if necessary. The complete lab process from Accessioning through Confirmation is reviewed 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 period: Hair drug tests can identify drug use for up to 90 days, contrary to urine tests which have a shorter detection span.
• Difficult to deceive: It is highly challenging to deceive a hair drug test, thus enhancing the accuracy of the results.
• Offers historical insight: It can illustrate a pattern of drug consumption over a timeline, as opposed to merely recent use.

Limitations:

• Inability to detect recent consumption: It requires roughly 5-7 days for drugs to manifest in hair.
• Expense: Hair drug tests are typically costlier than alternative drug testing techniques.
• Result variations: Elements such as hair color and personal discrepancies in hair growth can influence the concentration of drug metabolites within the hair.

Note: Although often called "hair follicle tests", the analysis is performed on 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.
