Hair Follicle Drug Testing - Delta, IA

What it is, How it works

Hair testing has emerged as an effective means for identifying drug and alcohol consumption. Hair offers a detailed, long-view history of substance use by embedding biomarkers within the strands as they grow. When obtained near the scalp, hair can identify substance use for a detection span of around 90 days. Collecting hair is straightforward, relatively tamper-proof, and straightforward to transport.

Collecting a 1.5-inch segment of roughly 200 hair strands (similar in size to a #2 pencil) near the scalp provides 100mg, which is ideal for both initial screening and confirmation. For EtG, additional substances, or tests exceeding 10-panel, 150mg is advised. We suggest weighing the sample using a jeweler’s scale. If scalp hair is unavailable, equivalent body hair may be gathered. When discussing head hair, we're specifically referring to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result entails four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning comprises the sample’s initial integration into the laboratory's system, ensuring it was correctly sealed and sent, generating a unique LAN (Laboratory Accessioning Number), and filling in any supplementary data entry missing from an electronic chain of custody system.

Screening serves as an initial assessment for substances of abuse. While cost-effective for eliminating drug use in most samples, a positive screen requires confirmation to be legally valid. Samples that yield presumptively positive results during Screening need a subsequent verification.

Should a sample appear positive in the Screening phase, additional hair is drawn from the original sample for Extraction. In this phase, drugs are isolated from hair at lower concentrations compared to alternatives (e.g., urine, oral fluid), making hair drug screening the most intricate to execute.

Verification of any positive screening result is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are soaked before confirmation as necessary. The entire lab process, from Accessioning through Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Long detection window: Hair drug tests recognize drug use for as long as 90 days, whereas urine tests have a briefer detection period.
• Difficulty to cheat: Cheating on a hair drug test is notably challenging, resulting in more accurate outcomes.
• Provides historical data: It charts a drug usage pattern over time, rather than merely recent use.

Limitations:

• Cannot detect recent use: Detection in hair takes about 5-7 days post-use.
• Cost: Hair drug tests often incur higher costs than alternative methods.
• Variations in results: Aspects such as hair color and individual growth rates can influence drug metabolite concentrations in hair.

Note: Commonly termed as "hair follicle tests", the analysis targets the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Delta, IA, hair follicle testing triumphs over traditional urine testing due to its superior detection duration and reliability. By choosing hair samples, you access a more comprehensive history of substance use, eliminating uncertainties.

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.
