Hair Follicle Drug Testing - Saint Joe, AR

What it is, How it works

Hair testing is recognized as an effective means for detecting drug and alcohol consumption. The fibers of hair strands trap biomarkers, offering a long-term record of substance use. Hair obtained from near the scalp can provide a detection period of up to three months for alcohol and drugs. It's easy to collect, relatively tamper-resistant, and convenient to transport.

A 1.5-inch sample consisting of roughly 200 hair strands (around the size of a #2 pencil) nearest to the scalp results in 100mg of hair, which is the optimal amount for initial and confirmatory testing. For EtG, additional testing, or panels above 10, 150mg of hair is advisable. Using a jeweler’s scale is suggested for weighing the sample. If scalp hair isn't available, an equivalent amount of body hair should be obtained. The reference to head hair specifically denotes scalp hair, while body hair includes all other types (such as facial and axillary).

Process Overview

The laboratory processing for drug test results involves four main stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first step where a sample is integrated into a lab's system. This includes verifying proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data entry beyond what's provided in an electronic chain of custody.

Screening serves as an initial rapid evaluation for substances of abuse. Screening is cost-efficient for excluding drug use in most cases; however, a positive screen requires validation to be court-admissible. Presumptive positives in Screening must undergo further confirmation.

A presumptive positive from the Screening stage leads to more hair being taken from the primary sample for Extraction. Drugs are extracted from hair at much lower concentrations than other methods (such as urine or oral fluid), making hair drug testing one of the most challenging methodologies.

Confirmation of positive screening results is completed using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed as necessary before confirmation. The full lab process from Accessioning to Confirmation is overseen according to both the CAP (College of American Pathologists) Hair criteria and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests detect substance use for up to 90 days, while urine tests have shorter detection spans.
• Hard to manipulate: Cheating on a hair drug test is very challenging, resulting in more reliable outcomes.
• Chronological data: It provides an overview of drug use patterns over time, not just recent use.

Limitations:

• Recent use undetectable: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug testing tends to be pricier than other testing methods.
• Result variability: Factors like hair color and personal hair growth differences can influence drug metabolite concentrations.

Note: Despite being popularly termed "hair follicle tests," the test evaluates the hair strand itself, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why does hair follicle testing surpass urine testing in Saint Joe, AR? Hair testing offers superior detection accuracy and provides a clearer indication of long-term substance use.

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.
