Hair Follicle Drug Testing - Scotia, CA

What it is, How it works

Hair sampling has emerged as a robust method for identifying drug and alcohol consumption. Strands of hair offer an extended history of alcohol and other substances, enclosing biomarkers within the fiber of the growing strand. When taken close to the scalp, hair can provide roughly a 3-month detection window for alcohol and substances. It's easy to collect, challenging to tamper with, and simple to send.

A sample length of 1.5 inches, roughly 200 hair strands (similar to the size of a #2 pencil), cut nearest to the scalp will deliver 100mg of hair, which is optimal for screening and confirmation. For EtG, additional tests, and/or panels beyond 10, a specimen of 150mg is recommended. It's advisable to weigh the hair on a jeweler’s scale. If scalp hair isn't available, the equivalent quantity of body hair can be used. Head hair refers solely to scalp hair, while body hair denotes other types (facial, axillary, etc.).

Process Overview

Laboratory processing of a drug test result encompasses four core steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the initial processing of a specimen into a lab's system. This step includes ensuring the sample was properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and finishing any additional data entry not covered by an electronic chain of custody system.

Screening is a preliminary check for substance abuse. While cost-effective for ruling out drug use in most samples, a positive screen must be confirmed to stand in court. Presumptively positive samples from screening require confirmation.

If positive in Screening, an additional sample from the initial hair is prepared for Extraction. In this phase, substances are isolated from hair at significantly lower concentrations than in other methods (such as urine or oral fluid), making hair drug screening particularly challenging.

Any positive screening is confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample undergoes washing as needed before confirmation. The entire lab operation, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair testing can detect drug usage up to 90 days back, in contrast to urine tests, which have a shorter window.
• Difficult to deceive: It's tough to cheat a hair drug test, enhancing result accuracy.
• Chronological data: It offers a timeline of drug usage over time, not just recent intake.

Limitations:

• Cannot detect recent usage: Drugs take approximately 5-7 days to be traceable in hair.
• Expense: Hair drug tests are often pricier than other methods.
• Variation in results: Factors such as hair color and personal hair growth can influence drug metabolite levels in hair.

Note: Commonly called "hair follicle tests," the analysis is performed on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

For Scotia, CA, the edge of hair follicle testing over urine testing is evident. Hair methods boast superior detection accuracy and reliability, capturing a wider window of drug use.

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.
