Hair Follicle Drug Testing - Paradise Valley, NV

What it is, How it works

Hair testing is recognized as an effective means for identifying drug and alcohol consumption. Hair captures a comprehensive timeline of substance use by embedding biomarkers within the growing strand's fibers. If gathered near the scalp, hair can reveal alcohol and drug presence for approximately three months. Collection is straightforward, challenging to tamper with, and easy to transport.

A 1.5-inch segment of about 200 hair strands (about a #2 pencil's thickness) nearest to the scalp yields 100mg, the optimal quantity for screening and validation. For EtG, supplementary tests, and/or tests exceeding 10 panels, 150mg of the sample is advisable. It is recommended to use a jeweler’s scale for weighing the sample. Should scalp hair be unavailable, an equivalent amount of body hair is collectable. "Head hair" specifically denotes scalp hair. "Body hair" encompasses all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning is the preliminary step where samples are entered into a lab's system. This involves ensuring correct sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data input absent from an electronic chain of custody system.

Screening entails an initial rapid assessment for drug abuse. Although Screening is a cost-efficient method to dismiss drug use in most samples, positive results must be verified for legal admissibility. Samples showing presumptive positivity in Screening necessitate further confirmation.

Should a sample be presumptively positive in the Screening stage, additional hair is sourced from the initial specimen and prepped for Extraction. At this phase, drugs are extracted from hair at a much lower concentration than other methods (ex. urine or oral fluid), which is why hair drug screening is the most challenging method to execute.

Confirmation of any positive screening results is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation as necessary. The comprehensive lab process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, whereas urine tests have a more limited detection timeframe.
• Challenges in falsification: Cheating a hair drug test is quite difficult, enhancing result reliability.
• Delivers historical insights: It can indicate a pattern of drug use over time, not merely recent activity.

Limitations:

• Inability to detect recent usage: It takes around 5-7 days for drugs to be noticeable in hair.
• Expense: Hair drug tests are typically costlier than other testing methods.
• Result variability: Elements like hair color and individual variations in hair growth can affect drug metabolite concentrations in hair.

Note: Despite often being called "hair follicle tests", the analysis focuses on the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair vs. Urine Testing: In Paradise Valley, NV, hair follicle testing outshines traditional urine tests concerning detection accuracy and reliability.

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.
