Hair Follicle Drug Testing - Cheriton, VA

What it is, How it works

Hair testing has become a widely recognized tool for identifying drug and alcohol consumption. Hair retains a long-term record of alcohol and drug usage by capturing biomarkers within the strands of the hair as it grows. When taken near the scalp, hair may offer around a 3-month time frame for detecting the presence of alcohol and other drugs. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.

A sample of 1.5 inches consisting of approximately 200 hair strands (comparable to the girth of a #2 pencil) nearest the scalp yields 100mg of hair, which serves as the perfect sample size for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the substance is advisable. It is suggested to measure the specimen using a jeweler’s scale. In the event that scalp hair is unavailable, an equivalent amount of body hair may be gathered. In reference to head hair, we mean solely scalp hair, while body hair pertains to all other types (facial, axillary, etc.).

Process Overview

The key phases in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the early processing of a sample into a lab’s system. This procedure covers confirming the sample was properly sealed and shipped, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any supplemental data input lacking from an electronic chain of custody system.

Screening involves an initial rapid check for illicit drug use. While it is an economical approach to eliminate drug use for most samples, a positive screen necessitates confirmation to be valid in court. Any samples preliminarily positive in Screening require secondary confirmation.

If a sample proves to be preliminarily positive in the Screening phase, additional hair is extracted from the original specimen and prepared for Extraction. During this phase, drugs are retrieved from hair at much lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to undertake.

Confirmation of any positive screening outcome involves the use of GC/MS, GC/MS/MS, or LC/MS/MS. All preliminary positive samples undergo washing before confirmation as needed. The whole lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a more limited detection period.
• Difficult to fool: Cheating a hair drug test is considerably challenging, enhancing the accuracy of the results.
• Provides historical insight: It can represent a pattern of drug use over extended times, not just recent consumption.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair after about 5-7 days.
• Expense: Hair drug tests generally cost more than other drug-testing methods.
• Result variability: Aspects like hair color and personal differences in hair growth may impact the drug metabolite levels in the hair.

Note: Although commonly referred to as "hair follicle tests", the test itself analyzes the strand of hair rather than 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.
