Hair Follicle Drug Testing - Saint Charles, MD

What it is, How it works

Hair testing is widely recognized as a robust method for detecting drug and alcohol consumption. Hair serves as a chronological record of substance use by capturing biomarkers within the fibers of the emerging hair strand. When sampled near the scalp, hair can offer up to a three-month window of detectability for alcohol and other substances. It is straightforward to collect, challenging to tamper with, and simple to transport.

A sample length of 1.5 inches, comprising roughly 200 hair strands (similar to a #2 pencil's thickness) closest to the scalp, yields 100mg of hair, which is the optimal amount for both screening and confirmation. For more extensive tests like EtG, add-ons, and panels exceeding 10, 150mg is advised. It's best to use a jeweler’s scale for measuring the specimen. In cases where scalp hair is not available, an equivalent quantity of body hair may be gathered. Reference to head hair denotes only scalp hair, while body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The core phases in laboratory analysis of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, a sample is initially processed into a lab’s system, ensuring correct sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and conducting any additional data entry that isn't rendered by an electronic chain of custody system.

Screening involves a rapid preliminary assessment for drugs. While cost-effective in dismissing drug use in most samples, any positive results need confirmation to be valid in legal proceedings. Samples displaying presumptive positive results in Screening require further confirmation.

For samples showing presumptive positives during Screening, further hair is extracted from the initial sample for the Extraction phase. Here, drugs are extracted from hair at considerably lower concentrations than other methods (such as urine or oral fluid), adding to the complexity of hair drug screening.

Confirmation of any positive screening result occurs via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation where necessary. The whole lab process from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests identify drug use for up to 90 days, unlike urine tests which are more limited.
• Hard to falsify: Tampering with a hair drug test is notably difficult, leading to more reliable outcomes.
• Offers historical use patterns: It outlines drug usage patterns over time, unlike spotting just recent use.

Limitations:

• Inability to detect recent use: It requires about 5-7 days for drugs to be traceable in hair.
• Expense: Hair tests are typically costlier than other testing options.
• Result variability: Aspects like hair color and individual hair growth differences can influence drug metabolite levels in hair.

Note: Although dubbed "hair follicle tests", the procedure examines the hair shaft, 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.
