Hair Follicle Drug Testing - Fort Winnebago, WI

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair offers an extended record of alcohol and drug use by embedding biomarkers within the strands as the hair grows. When cut near the scalp, hair can present roughly a 3-month timeline for detecting alcohol and drugs. Hair is easy to gather, moderately challenging to tamper with, and simple to send.

A 1.5-inch sample consisting of about 200 hair strands (approximately the width of a #2 pencil) nearest to the scalp yields 100mg, which is the prime amount for testing and verification. For EtG, additional requests, and/or tests surpassing 10 panels, a 150mg sample is advised. We suggest weighing the sample with a jeweler's scale. If scalp hair is unavailable, a comparable amount of body hair can be used. When we mention head hair, we mean scalp hair exclusively. Body hair refers to all other types of hair (facial, axillary, etc.).

Process Overview

The four crucial phases in the lab assessment of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning incorporates the preliminary treatment of a sample into a lab's system. This comprises confirming the sample was sealed and sent correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any supplemental data entry not covered by an electronic custody chain.

Screening entails an initial rapid assessment for the presence of abused drugs. Although Screening is an economical means to dismiss drug usage for most samples, a positive screen must be verified to be court-admissible. Any samples that are tentatively positive in Screening warrant a follow-up confirmation.

When a sample is tentatively positive in the Screening process, additional hair is extracted from the primary sample and prepared for Extraction. During this phase, substances are withdrawn from hair at a lower concentration than other methods (e.g., urine or oral fluid), which is why hair drug testing is the most complex method to execute.

Confirmation for any positive screen is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation if required. The entire lab procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use up to 90 days, while urine tests offer a shorter detection period.
• Challenge to deceive: Cheating a hair drug test is quite difficult, which enhances result accuracy.
• Offers historical insight: It can display a pattern of drug use over time, not merely recent use.

Limitations:

• Inability to detect recent use: It takes around 5-7 days for drugs to show in hair.
• Expense: Hair drug tests generally cost more than other testing methods.
• Result variations: Elements like hair color and personal hair growth differences can influence drug metabolite concentration in hair.

Note: Despite being called "hair follicle tests," the analysis is conducted 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.

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.

Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols.
