Hair Follicle Drug Testing - Yates City, IL

What it is, How it works

Hair testing has established itself as an effective method for identifying drug and alcohol consumption. The fibers of a growing hair strand capture biomarkers, offering a historical record of alcohol and other drugs. Hair collected near the scalp provides about a three-month detection window for alcohol and drugs. Hair collection is also straightforward, hard to tamper with, and easy to transport.

A 1.5-inch sample consisting of approximately 200 hair strands (roughly the size of a #2 pencil) nearest to the scalp offers 100mg of hair, the perfect amount for screening and confirmation. For EtG, additional tests, or panels above 10, 150mg of the sample is advisable. It's best to weigh the specimen using a jeweler’s scale. In the absence of scalp hair, a similar quantity of body hair can be collected. "Head hair" refers solely to scalp hair, while "body hair" covers all other types (facial, axillary, etc.).

Process Overview

The main steps in lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase where a sample is processed into a laboratory system. This step involves confirming proper sealing and shipping of the sample, assigning it a random LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody system.

Screening is a preliminary check for drugs of abuse. Although Screening is a cost-effective way to eliminate drug usage on most samples, a positive result needs confirmation to be legally admissible. Any presumptive positive samples in Screening require further confirmation.

When a sample shows presumptive positivity during Screening, more hair is extracted from the initial specimen for the Extraction phase. During this phase, drugs are retrieved from hair at lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug screening a challenging methodology.

Confirmation of any positive Screening results is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed as necessary before confirmation. The entire lab process from Accessioning to Confirmation undergoes review under both CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can detect drug use for up to 90 days, unlike urine tests which are shorter.
• Difficulty to cheat: Hair drug tests are challenging to tamper with, enhancing result accuracy.
• Provides historical data: It identifies a pattern of drug use over time, beyond just recent usage.

Limitations:

• Cannot detect recent use: Detecting drugs in hair takes about 5-7 days.
• Cost: Hair drug tests tend to be pricier than other methods.
• Variations in results: Factors such as hair color and individual hair growth can impact drug metabolite concentration in hair.

Note: While often called "hair follicle tests", the test actually examines 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.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
