Hair Follicle Drug Testing - Parker Strip, AZ

What it is, How it works

Regarded as an effective method, hair testing serves in detecting drug and alcohol consumption. Hair fibers trap biomarkers within the strand, offering a prolonged timeline of alcohol and drug use. When taken near the scalp, a hair test can present a detection range of nearly 3 months for substances. Collection is straightforward, resistant to tampering, and conveniently shippable.

A 1.5-inch hair sample comprising roughly 200 strands (approximating a #2 pencil) from the scalp provides 100mg, the optimal amount for both screening and confirmation procedures. For EtG, additional tests, or panels exceeding 10, a specimen of 150mg is advisable. Utilizing a jeweler’s scale for weighing the sample is suggested. Should scalp hair be inaccessible, a similar quantity of body hair can be used. References to head hair apply solely to scalp hair, whereas body hair encompasses all other variants like facial and axillary types.

Process Overview

Accessioning, Screening, Extraction, and Confirmation are the four key steps in processing drug test results in the lab.

Accessioning includes the sample's initial entry into the lab's system, confirming it was correctly sealed and shipped, assigning a LAN (Laboratory Accessioning Number), and filling in any supplementary data absent from an electronic chain of custody.

Screening entails a preliminary rapid check for drug presence. While cost-effective for excluding drug use across most samples, a positive outcome requires confirmation for court usability. Any samples testing positive in Screening need secondary verification.

For samples testing positive in Screening, additional hair is extracted from the primary sample and readied for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology.

Confirmed positive results are validated using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, suspected positive samples are washed if necessary. Every step from Accessioning to Confirmation is scrutinized under CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Capable of detecting drug intake for up to 90 days, contrasting with the shorter window of urine tests.
• Challenging to falsify: The difficulty in manipulating hair drug tests ensures greater accuracy.
• Supplies historical insights: Offers a usage pattern over time, not merely recent consumption.

Limitations:

• Inability to detect immediate use: Drugs become detectable in hair roughly 5-7 days post-consumption.
• Expense: Generally, hair drug tests incur higher costs than alternative testing methods.
• Result variations: Hair color and individual growth rate variations can influence drug metabolite concentration in hair.

Note: Widely known as "hair follicle tests", the examination targets the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle tests surpass traditional urine tests for several reasons in Parker Strip, AZ. One key advantage is their enhanced accuracy, capturing a longer history of substance use. This prolonged detection window gives a comprehensive insight into an individual's consumption habits, offering reliability that urine tests struggle to match, particularly for long-term assessments.

Extended Detection Window

The extended detection window of hair follicle testing in Parker Strip, AZ, is a distinct advantage.

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.
