Hair Follicle Drug Testing - Central Contra Costa, CA

What it is, How it works

Hair testing has emerged as an influential method for detecting drug and alcohol consumption. Hair strands offer an extended historical record of alcohol and drug usage by capturing biomarkers within the strands' fibers as they grow. When hair is cut close to the scalp, it can offer an approximate 3-month timeframe for detecting alcohol and drug use. Hair collection is straightforward, moderately challenging to tamper with, and easy to transport.

A 1.5-inch section with around 200 hair strands (similar to the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG, additional tests, or assessments exceeding 10 panels, a 150mg sample is advised. It is recommended to weigh this specimen using a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair may be gathered. Head hair explicitly refers to scalp hair, whereas body hair encompasses other types like facial and axillary hair.

Process Overview

The four fundamental procedures in processing a drug test result in a lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning constitutes the first step of integrating a sample into a laboratory system. This process includes checking that the sample is sealed and dispatched correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any required data entry not supplied by an electronic chain of custody system.

Screening performs an initial rapid review for substances of abuse. Screening is cost-efficient for excluding drug usage in the majority of samples, but a positive result requires confirmation to be legally valid. Samples that show a presumptive positive in the Screening stage necessitate a subsequent confirmation.

If the Screening process yields a presumptive positive, additional hair is extracted from the original specimen for the Extraction stage. Here, drugs are isolated from hair at significantly lower concentrations compared to alternative methodologies (e.g., urine or saliva), making hair drug testing the most intricate methodology.

A positive screening outcome is confirmed with GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positives are cleansed before undergoing confirmation as necessary. The comprehensive laboratory process, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair category and the accreditation aligned with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can reveal drug use over a duration of up to 90 days, in contrast to urine tests, which have a shorter detection span.
• Challenging to falsify: Cheating a hair drug test is notably difficult, leading to higher reliability of results.
• Offers historical insights: It supplies an overview of drug usage patterns over time, not merely recent activities.

Limitations:

• Incapable of detecting recent use: Drugs become identifiable in hair after roughly 5-7 days from usage.
• Expensive: Typically, hair drug tests are pricier than other drug testing approaches.
• Variable outcomes: Elements such as hair color and individual hair growth variability can sway the drug metabolite levels in hair.

Note: Although commonly termed "hair follicle tests," the procedure examines the hair strand, not the follicle beneath the scalp

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.
