Hair Follicle Drug Testing - Rison, AR

What it is, How it works

Hair testing is now viewed as a significant resource in identifying drug and alcohol consumption. Hair chronicles an extended history of substances like alcohol by embedding biomarkers within the fiber of the hair as it grows. Collected near the scalp, hair offers a detection timeframe of up to around 3 months for alcohol and other drugs. Hair collection is straightforward, relatively hard to tamper with, and convenient to transport.

An inch and a half segment comprising roughly 200 hair strands (comparable to the diameter of a #2 pencil) nearest to the scalp yields 100mg, ideal for screening and confirmation purposes. For EtG, extended panels, and/or tests exceeding 10 panels, 150mg of the sample is advised. Utilizing a jeweler’s scale to weigh the specimen is recommended. If head hair is not accessible, a similar quantity of body hair can be collected. "Head hair" refers strictly to scalp hair. "Body hair" includes all other types (facial, axillary, etc.).

Process Overview

The pivotal stages in the lab processing of a drug test result comprise Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary integration of a sample into a laboratory's framework. This step verifies if the sample was sealed and dispatched accurately, designates a random LAN (Laboratory Accessioning Number), and finalizes any extra data entry absent in an electronic chain of custody system.

Screening is a preliminary rapid assessment for substance abuse. Though Screening effectively rules out drug usage in most cases, a positive screen must be verified to be permissible in court. Samples with a presumptive positive outcome during Screening necessitate an additional confirmation.

Should a sample yield a presumptive positive in Screening, more hair is extracted from the initial sample and prepped for Extraction. In Extraction, drugs are withdrawn from hair at significant dilution levels compared to other methods (e.g., urine or oral fluid), highlighting why hair drug screening is notably challenging to execute.

Validating any positive result from Screening is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. The comprehensive lab process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests can identify drug consumption for up to 90 days, as opposed to urine tests with a shorter detection window.
• Difficult to manipulate: The difficulty in falsifying a hair test renders the results more precise.
• Records historical usage: It can exhibit a usage pattern over time, extending beyond recent activity.

Limitations:

• Unable to detect recent usage: Drugs become traceable in hair approximately 5-7 days post-consumption.
• Expense: Hair tests are typically pricier than alternative testing techniques.
• Result variations: Elements like hair color and individual hair growth differences can alter drug metabolite concentrations in hair.

Note: Though often termed "hair follicle tests", this test scrutinizes the hair strand rather than the follicle located under 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.
