Hair Follicle Drug Testing - Cedar Creek, NE

What it is, How it works

The use of hair analysis has gained recognition as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of substance use by embedding biomarkers within the strands of hair as it grows. When sampled near the scalp, hair can reveal a detection period of up to three months for various substances, including alcohol. The process of obtaining hair samples is straightforward, challenging to tamper with, and convenient to transport.

An ideal sample for testing and verification, measuring 1.5 inches and consisting of roughly 200 strands (equivalent to a #2 pencil's width), amounts to 100mg. For additional testing, such as EtG or assessments surpassing 10 panels, a 150mg sample is advised. It's suggested to use a jeweler's scale for accurate measurement. In instances where scalp hair is unavailable, an equivalent volume of body hair can be used. When mentioning head hair, it strictly pertains to scalp hair. Body hair encompasses all other types, such as facial and axillary hair.

Process Overview

The laboratory drug testing workflow consists of four essential stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial task of integrating a sample into the laboratory system. This process involves ensuring the secure sealing and shipment of samples, generating a unique LAN (Laboratory Accessioning Number), and completing any requisite data entry absent from the electronic chain of custody records.

Screening is a preliminary assessment aimed at detecting substance abuse. Although cost-effective and effective for eliminating drug presence in the majority of samples, any positive findings in Screening require confirmation to be deemed valid in legal settings. Samples yielding presumptive positive results in Screening necessitate secondary confirmation.

Upon obtaining a presumptive positive result at the Screening stage, additional hair is extracted from the original sample for Extraction. In this phase, substances are isolated from hair at lower concentrations compared to alternative methods (e.g., urine or oral fluid), making hair drug screening a particularly intricate technique.

The Confirmation step for positive screening outcomes utilizes GC/MS, GC/MS/MS, or LC/MS/MS. Any samples with presumptive positive results undergo washing before confirmation if necessary. The comprehensive laboratory analysis, encompassing Accessioning through Confirmation, is conducted in compliance with CAP (College of American Pathologists) Hair accreditation and ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can report drug use for as long as 90 days, contrasting with the briefer detection window of urine tests.
• Challenging to manipulate: The difficulty of falsifying a hair drug test enhances the accuracy of results.
• Historical usage data: Hair tests can depict a sustained pattern of drug use, rather than just recent consumption.

Limitations:

• Cannot detect recent use: It typically takes 5-7 days for drugs to become detectable in hair after use.
• Cost: Hair drug testing usually incurs higher expenses compared to other methods of drug testing.
• Result variability: Factors such as hair color and individual differences in hair growth can influence the concentration levels of drug metabolites in the hair.

Note: Though frequently termed "hair follicle tests", the procedure actually examines the hair strand itself 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.

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.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis.
