Hair Follicle Drug Testing - Nunam Iqua, AK

What it is, How it works

Hair testing is recognized as a significant method for detecting substance use, including alcohol. As hair grows, it captures biomarkers within its strands, offering an extended timeline of substance usage. A sample collected near the scalp can reveal drug and alcohol use dating back up to three months. The collection process is straightforward, tough to tamper with, and can be easily dispatched.

A sample measuring 1.5 inches in length consisting of roughly 200 hairs (similar in width to a #2 pencil) near the scalp yields 100mg of hair, which is ideal for analysis. For tests such as EtG, additional screenings, or those exceeding 10-panel tests, it's advisable to have a sample weighing 150mg. It's best to verify the weight using a jeweler’s scale. If scalp hair is not an option, one can gather a comparable amount of body hair. References to head hair specifically mean scalp hair. Body hair covers all other types, like facial or underarm hair.

Process Overview

Lab processing of drug test results encompasses Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to categorizing a specimen within a lab's system. This phase checks if the sample was appropriately sealed and dispatched, assigns a LAN (Laboratory Accessioning Number), and handles any additional data entry required outside an electronic chain of custody framework.

During Screening, the sample undergoes an initial assessment for substances. It's a predominantly economical method to dismiss potential drug use in most samples, although a positive Screening result necessitates Confirmation for court acceptance. Any sample showing initial positivity in Screening must undergo further confirmation.

If the Screening flags a sample as likely positive, additional hair is taken from the original sample for Extraction. Here, substances are retrieved from hair at substantially lower concentrations compared to other testing methods like urine. This attribute makes hair drug screenings particularly challenging to execute.

Confirmation of any positive screen result is pursued via GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Samples that test positive initially are cleaned prior to definitive confirmation, as required. The entire lab process, from Accessioning to Confirmation, is inspected in line with CAP (College of American Pathologists) regulations on Hair testing and ISO/IEC 17025 accreditation standards.

Benefits of hair drug testing:

• Extended detection period: Hair tests can trace substance use for a maximum of 90 days, surpassing the briefer window of urine tests.
• Hard to circumvent: The accuracy of hair drug tests is high due to the difficulty of tampering with them.
• Assess patterns: Hair testing can disclose a trend of substance use over time, rather than recent usage alone.

Shortcomings:

• No detection of immediate use: Drugs typically take about 5-7 days to become detectable in hair.
• Higher pricing: Hair drug tests often come with a higher cost than other testing methods.
• Result variations: Elements like hair color and individual hair growth can influence metabolite levels in hair.

Note: Often dubbed as "hair follicle tests", these tests analyze 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.
