Hair Follicle Drug Testing - Wilna, NM

What it is, How it works

Hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair provides long-term evidence of alcohol and other drugs by capturing biomarkers within the strands during growth. When collected near the scalp, hair can offer a drug and alcohol detection period of up to about three months. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A 1.5-inch segment of roughly 200 hair strands (similar in size to a #2 pencil) nearest to the scalp yields 100mg, forming the perfect sample for analysis and verification. For EtG, add-ons, and/or evaluations exceeding 10 panels, a 150mg sample is advisable. We advise measuring the sample using a jeweler’s scale. If scalp hair is unavailable, an equivalent amount of body hair can be gathered. When discussing head hair, we are specifically referring to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test is divided into four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial introduction of a sample into a laboratory’s system. This process ensures the sample’s proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes any necessary data entry absent from an electronic chain of custody system.

Screening includes a preliminary evaluation for drugs of abuse. Screening is an efficient method to exclude drug usage in most samples; however, a positive screen needs validation to be court-admissible. Any samples with presumptive positive results during Screening require further confirmation.

If a sample demonstrates a presumptive positive in the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), making hair drug screening the most challenging method to execute.

Confirmation of any positive screen outcome is conducted using methods such as GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens undergo washing prior to confirmation as necessary. The entire laboratory process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection timeframe.
• Harder to deceive: Cheating a hair drug test is extremely challenging, ensuring more precise results.
• Offers historical insight: It provides a pattern of drug usage over time, beyond just recent consumption.

Limitations:

• Cannot detect recent use: A period of 5-7 days is required for drugs to be identifiable in hair.
• Expensive: Hair drug tests typically cost more than other drug testing approaches.
• Result variability: Factors like hair color and individual hair growth rates can influence the concentration of drug metabolites in hair.

Note: Though commonly known as "hair follicle tests", the analysis focuses on the hair strand itself, 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.
