Hair Follicle Drug Testing - Silverado, CA

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of alcohol and drug exposure by embedding biomarkers within the fibers of the strand as it grows. When collected near the scalp, a hair sample can reveal up to a 3-month period of drug and alcohol use. Hair collection is straightforward, hard to tamper with, and easy to transport.

A 1.5-inch portion of approximately 200 hair strands (comparable to the thickness of a #2 pencil) taken from near the scalp will yield 100mg of hair, the perfect amount for screening and confirmation tests. For EtG, additional panels, or tests exceeding 10 panels, a 150mg specimen is advised. Using a jeweler’s scale to weigh the sample is suggested. In cases where scalp hair is not available, a similar quantity of body hair can be used. The term head hair specifically denotes scalp hair, while body hair encompasses all other types (like facial or axillary hair).

Process Overview

The key phases in processing a drug test result at the laboratory include Accessioning, Screening, Extraction, and Confirmation.

The Accessioning phase is when a sample first enters a laboratory’s system. This step ensures the sample was appropriately sealed and delivered, assigns a unique LAN (Laboratory Accessioning Number), and includes any additional data entry not handled by an electronic chain of custody system.

Screening acts as an initial overview for drugs of abuse. While it offers a cost-efficient way to exclude drug use from most samples, any positive screen must be confirmed to be valid in legal settings. Samples with presumed positive results in Screening need a secondary confirmation.

Should a sample be deemed presumptively positive during Screening, additional hair is extracted from the original specimen for the Extraction phase. In this phase, drugs are extracted from hair at a significantly lower concentration than other methods (like urine or oral fluid), making hair drug testing the most challenging methodology.

Confirmation for any positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples that are presumptively positive undergo a washing process before confirmation, if necessary. The entire lab process, from Accessioning to Confirmation, adheres to the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug usage for up to 90 days, unlike urine tests, which have a narrower detection range.
• Hard to manipulate: It is notably challenging to falsify a hair drug test, thereby enhancing the accuracy of the results.
• Offers historical insight: It shows a timeline of drug usage over a significant period, rather than just recent usage.

Limitations:

• Inability to detect recent usage: Drugs take roughly 5-7 days to become traceable in hair.
• Expense: Hair drug tests tend to be pricier than other forms of drug testing.
• Result variability: Variables such as hair color and individual differences in hair growth can influence the level of drug metabolites in the hair.

Note: Commonly termed as "hair follicle tests", the actual analysis is performed on 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.

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.
