Hair Follicle Drug Testing - Odessa, DE

What it is, How it works

Utilizing hair testing has increasingly been recognized as an effective method for detecting both drug and alcohol consumption. Hair serves as a repository for long-term drug and alcohol usage history by encapsulating biomarkers within the strands' fibers as they grow. When hair samples are taken near the scalp, they can offer a detection timeframe that extends up to roughly three months for alcohol and other substances. Hair collection is straightforward, somewhat challenging to tamper with, and convenient for shipping.

A sample around 1.5 inches in length consisting of about 200 hair strands (approximate size of a #2 pencil) near the scalp provides 100mg of hair, considered the ideal amount for testing and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg sample is advisable. We suggest utilizing a jeweler's scale to weigh the hair sample. Should scalp hair be unattainable, an equivalent amount of body hair can be used. By head hair, we specifically mean scalp hair, whereas body hair includes all other types such as facial and axillary.

Process Overview

The principal phases in laboratory handling for drug test results are Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary processing of a sample as it enters a laboratory’s system. This phase encompasses verifying the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry not included in an electronic chain of custody system.

Screening entails an initial brief assessment for substance abuse. While Screening offers a budget-friendly means to dismiss drug use in most samples, a positive screen demands confirmation to be legally viable. Samples that test presumptively positive during Screening do need further confirmation.

If during Screening a sample tests presumptively positive, additional hair is extracted from the initial sample and readied for Extraction. In this stage, drug compounds are extracted from the hair in much lower concentrations than in alternative methods (e.g., urine or oral fluid), making hair drug testing the most intricate method.

Positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, all samples with presumptive positives are cleaned as needed. The complete laboratory sequence from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair classification and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can reveal drug usage for up to 90 days, unlike urine tests with a much shorter detection span.
• Difficulty to cheat: Cheating in a hair drug test is quite challenging, enhancing the result's accuracy.
• Provides historical data: It offers a timeline pattern of substance use over time, rather than just identifying recent use.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair after about 5-7 days.
• Cost: Hair drug testing is usually more costly than other testing methodologies.
• Variations in results: Individual differences like hair color and growth rates can impact drug metabolite concentrations in hair.

Note: While frequently known as "hair follicle tests", the analysis focuses on the hair strand, not the hair 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.
