Hair Follicle Drug Testing - Grandview, IL

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair offers a comprehensive timeline for alcohol and drug use by retaining biomarkers within the hair's fibers as it grows. When sourced near the scalp, hair can offer a detection timeline of up to 3 months for alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and easy to transport.

A sample measuring 1.5 inches, consisting of approximately 200 strands (roughly the diameter of a #2 pencil) closest to the scalp, provides 100mg, which is optimal for screening and confirmation. For EtG, add-ons, and tests exceeding 10 panels, 150mg is advisable. We suggest using a jeweler’s scale for weighing the sample. If scalp hair is unavailable, an equivalent quantity of body hair may be used. "Head hair" specifically refers to scalp hair, while "body hair" includes all other types (facial, axillary, etc.).

Process Overview

The laboratory drug testing procedure encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial sample processing within a laboratory's framework. This step includes ensuring the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data not available via an electronic chain of custody.

Screening is a preliminary assessment for drugs of abuse. Although Screening is a cost-efficient method to negate drug use in most cases, a positive result must be confirmed for legal admittance. Samples that are presumptively positive during Screening require further confirmation.

Presuming a sample tests positive in Screening, additional hair is gathered from the initial sample for Extraction. Within this phase, drugs are extracted from the hair at considerably lower concentrations than other methodologies (like urine or oral fluid), deeming hair drug testing as the most challenging method to perform.

Confirmation of any positive screening result is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo cleansing before confirmation as needed. The complete laboratory process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair tests can identify drug use for up to 90 days, compared to the shorter detection time of urine tests.
• Resistant to tampering: Cheating a hair drug test is exceedingly difficult, enhancing result accuracy.
• Historical insight: It can indicate a usage pattern over time, beyond just recent consumption.

Limitations:

• Inability to detect recent consumption: Drugs take around 5-7 days to be traceable in hair.
• Expense: Hair drug testing is typically pricier than other drug testing approaches.
• Result variations: Variables like hair color and personal differences in hair growth can influence drug metabolite concentration in hair.

Note: Despite often being called "hair follicle tests", the evaluation is conducted on the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Grandview, IL outshines urine testing with its superior detection capabilities.

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.
