Hair Follicle Drug Testing - Layhill, MD

What it is, How it works

Hair testing has gained recognition as an effective method for identifying drug and alcohol usage. Hair captures a long-term timeline of substances through trapping biomarkers in the hair strand's fibers as it grows. When hair is collected near the scalp, it can offer a detection period of nearly three months for drugs and alcohol. The collection process is straightforward, the chance of adulteration is minimized, and it is easy to transport.

A sample measuring 1.5 inches, consisting of around 200 hair strands (similar to a #2 pencil's size), closest to the scalp yields 100mg of hair, which is the optimal sample quantity for screening and confirmation. For tests involving EtG, additional panels, or those exceeding 10 panels, 150mg of the sample is advised. The sample weight should ideally be measured on a jeweler’s scale. If scalp hair is unavailable, an equivalent amount of body hair can be used instead. When we refer to head hair, it specifically means scalp hair, whereas body hair includes other types such as facial or axillary hair.

Process Overview

The laboratory processes a drug test result through four main steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning comprises the initial sample processing into the lab's system, including validating proper sample sealing and shipping, allocating a random LAN (Laboratory Accessioning Number), and completing additional data entry if electronic chain of custody data is lacking.

Screening is an initial rapid check for drug presence. Although cost-efficient for ruling out drug use in most samples, screenings require confirmation to be legally upheld. Any samples that preliminarily test positive in Screening necessitate secondary confirmation.

If screening indicates a presumptive positive, more hair is sourced from the initial sample for the Extraction stage. This phase involves extracting drugs from hair at much lower concentrations than other methods (e.g., urine or oral fluids), which makes hair drug screening notably challenging to execute.

Confirmation of any positive screening findings is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. Samples showing presumptive positivity undergo washing prior to confirmation as needed. The entire lab procedure, from Accessioning to Confirmation, complies with both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can uncover drug use spanning up to 90 days, unlike urine tests with a shorter time frame.
• Difficulty to cheat: Cheating a hair drug test is notably difficult, lending greater accuracy to the results.
• Provides historical data: It supplies a pattern of drug use over time, not just recent consumption.

Limitations:

• Cannot detect recent use: Drugs take about 5-7 days to become detectable in hair.
• Cost: Hair drug tests generally incur higher expenses than other testing modalities.
• Variations in results: Factors such as hair color and individual differences in hair growth can impact drug metabolite concentrations in hair.

Note: The term "hair follicle tests" is often used, but the test actually analyzes the hair strand, not the scalp's hair follicle.

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.
