Hair Follicle Drug Testing - Galion, LA

What it is, How it works

Hair analysis is now recognized as an effective method for identifying both drug and alcohol use. Hair offers a detailed timeline of alcohol and drug intake by encapsulating biomarkers within the hair strand's fibers as it grows. When gathered from near the scalp, hair can offer a detection period of roughly three months for alcohol and drugs. It's easy to collect hair, challenging to tamper with, and straightforward to transport.

A 1.5-inch segment, approximately the thickness of a #2 pencil, containing around 200 hairs near the scalp, amounts to 100mg of hair – the optimal sample size for screening and corroboration. For EtG, supplementary tests, or tests exceeding 10 panels, a specimen size of 150mg is advised. It's advisable to measure the sample using a jeweler’s scale. If scalp hair isn't accessible, a matching quantity of body hair can be acquired. When we talk about head hair, we specifically mean scalp hair. Body hair encompasses all other hair types, including facial and axillary hair.

Process Overview

The laboratory processing of a drug test result encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a lab's system. It involves ensuring the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and finalizing any further data entry not handled by an electronic chain of custody system.

Screening is an initial rapid assessment for illicit drug use. Though Screening is an economical way to eliminate drug usage in most samples, a positive outcome necessitates confirmation for court admissibility. Samples showing presumptive positivity in Screening require subsequent confirmation.

If a sample shows presumptive positivity at the Screening phase, more hair is extracted from the primary specimen and readied for Extraction. During this phase, drugs are drawn from hair at significantly lower concentrations compared to other methodologies (like urine or oral fluid), which is why hair drug analysis is among the most complex methodologies to conduct.

Positive screening outcomes are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo washing prior to confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Long detection period: Hair drug tests can reveal drug use for up to 90 days, surpassing the shorter detection period provided by urine tests.
• Hard to tamper with: Manipulating a hair drug test is extremely difficult, enhancing result accuracy.
• Offers historical data: It can unveil a pattern of drug use over time, not just recent usage.

Limitations:

• Cannot identify recent use: Drugs become detectable in hair approximately 5-7 days after usage.
• Cost: Generally, hair drug tests incur higher costs than other drug testing approaches.
• Variations in results: Factors like hair color and personal hair growth differences can impact drug metabolite concentrations in hair.

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