Hair Follicle Drug Testing - St. Louis, MI

What it is, How it works

Hair screening is now recognized as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of substances by retaining biomarkers within the strands of hair as they grow. When sourced near the scalp, hair can present nearly a 3-month detection timeframe for drugs and alcohol. Collecting hair is straightforward, relatively tamper-resistant, and easy to transport.

A sample measuring 1.5 inches, containing about 200 hairs (similar in width to a #2 pencil) nearest the scalp, produces 100mg of hair, the optimal amount for analysis and verification. For EtG assessments, additional components, and/or tests exceeding 10 panels, it is advised to use 150mg of the material. We suggest measuring the sample using a jeweler’s scale. In the absence of scalp hair, a comparable quantity of body hair may be utilized. When mentioning head hair, we refer solely to scalp hair. Body hair comprises all other types (facial, axillary, etc.).

Process Overview

The pivotal procedures in the lab processing of a drug test outcome encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the primary processing of a specimen within a lab’s framework. This process involves ensuring the sample is properly sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic custody documentation system.

Screening constitutes an initial rapid examination for drugs of abuse. Though Screening offers an economical solution to exclude drug usage in most samples, a positive result necessitates verification for legal acceptability. Samples showing tentative positivity during Screening need subsequent confirmation.

Upon preliminary positivity within the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. In this phase, substances are retrieved from hair at a substantially lower concentration compared to other methods (such as urine or oral fluid), making hair drug screening the most challenging method to execute.

Confirmation of any positive results in Screening occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All samples initially deemed positive undergo washing before confirmation as required. The comprehensive lab process from Accessioning to Confirmation undergoes evaluation under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests trace drug consumption for up to 90 days, unlike urine tests which have a briefer detection period.
• Resistance to dishonesty: Hair drug tests are highly resistant to tampering, ensuring accuracy in results.
• Reflects historical usage: These tests illustrate drug consumption patterns over sustained periods, rather than just recent use.

Limitations:

• Incapable of detecting recent consumption: Drugs take roughly 5-7 days to become detectable in hair.
• Expense: Hair drug testing typically incurs higher costs compared to other testing methodologies.
• Result disparities: Variables like hair color and distinct hair growth rates can influence metabolite concentration within the hair.

Note: Although often termed "hair follicle tests", the examination actually scrutinizes 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.
