Hair Follicle Drug Testing - Palermo, CA

What it is, How it works

Hair testing has evolved into a crucial method for identifying alcohol and drug consumption. Hair retains a prolonged history of substances by embedding biomarkers within the strands as they grow. When cut close to the scalp, hair delivers nearly a 3-month window for detecting substances, including alcohol. Hair is easy to collect, challenging to tamper with, and straightforward to send.

A 1.5-inch sample comprising roughly 200 hair strands (comparable to a #2 pencil’s thickness) nearest to the scalp yields 100mg, the optimal amount for analysis and verification. When testing for EtG, additional substances, or over 10 panels, a 150mg sample is advised. Utilizing a jeweler’s scale for weighing is recommended. Should scalp hair be unavailable, a similar quantity of body hair can be used. References to head hair pertain only to scalp hair. Body hair encompasses all other types, including facial and axillary hair.

Process Overview

The laboratory procedure for analyzing a drug test involves four principal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning focuses on the preliminary integration of a specimen into the lab’s system. This step involves ensuring the sample’s sealing and proper shipping, assigning a random LAN (Laboratory Accessioning Number), and filling in any absent data not covered by an electronic chain of custody.

Screening provides a preliminary assessment for drug presence. Although Screening offers a less costly method to eliminate drug usage in most samples, confirmed positive screens are necessary for court admissibility. Samples testing presumptively positive in Screening necessitate subsequent confirmation.

In cases where a Screening result is presumptively positive, additional hair from the original sample is utilized for the Extraction phase. During Extraction, drugs are separated from hair at substantially lower levels than other methods (e.g., urine or oral fluid), which underscores why hair drug screening is considered the most intricate method to execute.

Confirmed positive findings undergo GC/MS, GC/MS/MS, or LC/MS/MS procedures. All samples with presumptive positive outcomes are cleansed before confirmation, if required. The comprehensive lab process, from Accessioning through Confirmation, is examined under both the CAP (College of American Pathologists) Hair credential and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests reveal drug consumption for as long as 90 days, contrasted with urine tests that have shorter detection periods.
• Difficulty to cheat: Cheating on a hair drug test poses extreme difficulty, ensuring higher result accuracy.
• Provides historical data: It reveals a timeline of drug usage beyond just recent episodes.

Limitations:

• Cannot detect recent use: Drugs become traceable in hair roughly after 5-7 days.
• Cost: Hair drug testing typically incurs greater expense than alternative methods.
• Variations in results: Variables like hair color and personal hair growth differences might impact the metabolite concentration within hair.

Note: Often dubbed "hair follicle tests," the actual analysis focuses on the hair strand itself, not the follicle nestled under the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Palermo, CA, hair follicle testing outshines urine testing in multiple ways. Hair tests not only detect drug use over a longer timeline but also offer unmatched accuracy.

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.
