Hair Follicle Drug Testing - Webster, MD

What it is, How it works

Hair testing is recognized as an effective method for detecting drug and alcohol consumption. Hair retains evidence of alcohol and drugs by embedding biomarkers in its fibers as it grows. When collected near the scalp, a hair sample can reveal substance use over a period of up to three months. The collection process for hair is straightforward, it's challenging to tamper with, and it is simple to transport.

For sampling, a 1.5-inch segment from about 200 hair strands near the scalp, similar in size to a #2 pencil, provides 100mg of hair—suitable for both screening and confirmation. If tests for EtG, add-ons, or panels exceeding 10 are needed, 150mg is recommended. Using a jeweler’s scale for weighing the specimen is advisable. In cases where scalp hair isn't available, an equivalent amount of body hair can be utilized. The term 'head hair' refers specifically to scalp hair, while 'body hair' encompasses all other types such as facial, axillary, etc.

Process Overview

The laboratory processing for a drug test result involves four main stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially processed into the laboratory’s system, ensuring it was sealed and shipped correctly, assigning it a LAN (Laboratory Accessioning Number), and completing any remaining data entry not covered by an electronic chain of custody system.

Screening aims to quickly identify the presence of drugs. Although cost-effective for ruling out drug use in many samples, any sample that tests positive in Screening must undergo secondary confirmation to be considered valid in legal proceedings.

For samples that produce presumptive positives during Screening, additional hair is taken from the original sample and prepared for Extraction. This stage involves extracting drugs from hair at concentrations significantly lower than other methods (e.g., urine or oral fluid), making hair drug screening the most intricate methodology to perform.

Confirmation of positive screenings is carried out using methods like GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positives are cleansed as necessary. The complete laboratory sequence from Accessioning to Confirmation is evaluated following both the CAP (College of American Pathologists) Hair standards and is accredited according to ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests offer up to a 90-day detection period, surpassing the shorter duration of urine tests.
• Resistance to tampering: The reliability of hair drug tests is higher due to the difficulty in manipulating results.
• Chronological data provision: These tests deliver insight into drug usage over time rather than just recent consumption.

Limitations:

• Delayed detection capability: Drugs only become detectable in hair approximately 5-7 days after use.
• Expense: Compared to other methods, hair drug tests are generally pricier.
• Result variability: Factors such as hair color and individual hair growth differences can influence drug metabolite concentrations within the hair.

Note: Despite the common term "hair follicle tests", the examination actually involves the hair strand, not the follicle below the skin.

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.
