Hair Follicle Drug Testing - Marlow Heights, MD

What it is, How it works

Hair testing is increasingly regarded as an effective method for identifying drug and alcohol use. Hair captures long-term data on substances by encasing biomarkers within the strands as they grow. If collected near the scalp, hair can reveal drug and alcohol use up to a 3-month period. The collection process is straightforward, tampering is not easy, and shipping is convenient.

A sample of 1.5 inches containing approximately 200 hair strands (roughly the width of a #2 pencil) closest to the scalp provides 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, or those comprising more than 10 panels, 150mg of hair is suggested. It is advisable to use a jeweler’s scale to measure the specimen. In scenarios where scalp hair is not available, body hair can serve as an alternative. When discussing head hair, it specifically pertains to scalp hair. Body hair encompasses all other types (e.g., facial, axillary).

Process Overview

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

Accessioning is the initial step, where a sample is integrated into the lab’s system. This phase includes confirming the sample's proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and fulfilling any supplementary data input absent from an electronic chain of custody.

Screening is a preliminary check for drugs of abuse. While it is an economical method to exclude drug usage in most instances, a positive result in Screening necessitates a secondary confirmation for legal admissibility. Any samples showing a presumptively positive result in Screening require further confirmation.

For samples testing presumptively positive during Screening, additional hair from the original sample undergoes preparation for Extraction. During this phase, drugs are extracted from hair at lower concentrations compared to other techniques (such as urine or oral fluid), making hair drug screening a complex methodology.

Confirmation for any positive Screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples receive necessary washing prior to confirmation. The complete laboratory process from Accessioning to Confirmation is subject to review under CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can trace drug use for up to 90 days, unlike urine tests which have a shorter window.
• Difficulty to cheat: Manipulating results in a hair drug test is very challenging, leading to more reliable outcomes.
• Provides historical data: It shows a drug use pattern over a duration, not merely recent consumption.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair roughly 5-7 days after use.
• Cost: Hair drug tests typically incur higher costs compared to other testing methods.
• Variations in results: Individual differences in hair color and growth rates can influence drug metabolite concentration in hair.

Note: Referred to as "hair follicle tests", the examination focuses 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.
