Hair Follicle Drug Testing - San Juan Capistrano, CA

What it is, How it works

Hair examinations have emerged as a significant method for identifying drug and alcohol usage. Hair captures a long-term record of alcohol and substances by embedding biomarkers in the strands of the growing hair. When cut near the scalp, hair can reveal up to an estimated 3-month detection period for alcohol and drugs. Hair is easy to collect, relatively hard to tamper with, and straightforward to transport.

A 1.5-inch segment of about 200 hair strands (roughly the thickness of a #2 pencil) near the scalp yields 100mg of hair, which is the prime sample for screening and confirmation. For EtG, add-ons, and/or tests over 10 panels, 150mg of the sample is advised. Using a jeweler's scale to weigh the specimen is recommended. If scalp hair isn't available, an equivalent quantity of body hair may be taken. By head hair, we mean scalp hair exclusively. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The lab processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage of handling a sample into a lab's framework. This step verifies that the sample was sealed and transported correctly, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data entry not covered by an electronic chain of custody system.

Screening is a preliminary rapid assessment for drugs of abuse. While a cost-effective approach to exclude drug usage for most samples, a positive screen necessitates confirmation for court acceptance. Any samples identified as presumptively positive in Screening require a follow-up confirmation.

Upon identifying a sample as presumptively positive during Screening, more hair is extracted from the initial sample and prepared for Extraction. In this phase, drugs are drawn from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.

Confirmation of a positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicated as presumptive positives undergo washing before confirmation as necessary. The full laboratory procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the certification to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, in contrast to urine tests which have a shorter detection timeframe.
• Hard to deceive: Cheating a hair drug test is very challenging, ensuring more reliable results.
• Offers historical insights: It can present a drug use pattern over time, beyond just recent use.

Limitations:

• Cannot identify recent usage: Drugs take roughly 5-7 days to become traceable in hair.
• Expense: Hair drug tests are typically pricier than other drug testing approaches.
• Result variability: Factors like hair color and individual hair growth rates can influence the drug metabolite concentrations in hair.

Note: Although often called "hair follicle tests", the analysis targets the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
