Hair Follicle Drug Testing - Dennehotso, AZ

What it is, How it works

Hair analysis is increasingly acknowledged as an effective method for identifying drug and alcohol consumption. It offers an extended record of substance use by capturing biomarkers within the strands of developing hair. When taken near the scalp, hair can reveal substance consumption up to an estimated 3-month period. Collecting hair is straightforward, relatively tamper-proof, and simple to send.

A hair sample of 1.5 inches, consisting of approximately 200 strands (about the thickness of a #2 pencil) nearest to the scalp, provides the necessary 100mg needed for effective screening and verification. For EtG, additional tests, and/or screens beyond 10 panels, a 150mg sample is advisable. It's best to measure the sample with a jeweler's scale. If scalp hair is not an option, an equivalent amount of body hair may be used. When referring to head hair, we mean scalp hair specifically. Body hair refers to all other types (facial, axillary, etc.).

Process Overview

The drug testing laboratory process includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the introductory phase where a sample is processed into the lab's system. This involves ensuring the sample is properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data input that is not provided through an electronic custody chain.

Screening is a preliminary assessment for substance abuse. While cost-effective for ruling out drug use on most samples, any positive screening must be legally confirmed. Samples deemed presumptively positive in Screening require a follow-up confirmation.

When a sample tests presumptively positive during Screening, additional hair is extracted from the initial sample for further Extraction. In this phase, drugs are isolated from hair at significantly lower concentrations than in other testing methods (e.g., urine or oral fluid), making hair drug screening one of the most complex techniques to conduct.

Subsequent Confirmation of any positive results is carried out using GC/MS, GC/MS/MS, or LC/MS/MS methods. Before confirmation, all presumptive positive samples undergo washing if needed. The complete laboratory sequence from Accessioning to Confirmation is critically reviewed under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug screens reveal drug use for up to 90 days, contrasting with shorter detection periods in urine tests.
• Sophisticated to manipulate: The difficulty in cheating a hair drug screen increases result accuracy.
• Insightful past use: It offers a comprehensive record of drug usage patterns over time, not just recent consumption.

Limitations:

• Inability to detect recent use: It typically takes about 5-7 days for substances to appear in hair.
• Expense: Comparative to other drug screening methods, hair tests tend to be pricier.
• Result variability: Factors such as hair color and individual hair growth differences can impact drug metabolite concentration in hair samples.

Note: Although commonly termed "hair follicle tests", the evaluation is performed on the hair strand and 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
