Hair Follicle Drug Testing - Chillum, MD

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of a developing hair strand, hair offers a long-term historical record of alcohol and other substance use. If harvested near the scalp, hair has the capacity to offer a detection window extending up to about three months for alcohol and drugs. Collecting hair is straightforward, although altering it is somewhat challenging, and it is also easy to transport.

A sample measuring 1.5 inches, comprising roughly 200 hair strands (approximately the width of a #2 pencil) nearest to the scalp, yields 100mg of hair, which is optimal for both screening and verification. For tests like EtG, add-ons, or those exceeding 10 panels, a specimen of 150mg is suggested. We advocate using a jeweler’s scale for specimen weighing. If scalp hair isn't accessible, a similar quantity of body hair can be used. In references to head hair, we mean solely scalp hair. Body hair encompasses every other hair type (facial, axillary, etc.).

Process Overview

The lab processing of a drug test result comprises four chief steps: Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, a sample undergoes primary processing within the laboratory’s system. This phase includes ensuring the sample's proper sealing and dispatch, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry that an electronic chain of custody system might not provide.

Screening entails a preliminary rapid drug of abuse check. While Screening serves as a cost-effective strategy to dismiss drug consumption in the bulk of samples, any positive findings need confirmation to ensure courtroom admissibility. Samples exhibiting presumptive positivity in Screening necessitate further confirmation.

Should a sample display presumptive positivity during Screening, additional hair is extracted from the initial specimen for the Extraction stage. Here, drug extraction from hair occurs at a significantly lower concentration than other methods (e.g., urine or oral fluid); this complexity makes hair drug screening the most challenging methodology to execute.

Confirmation of any positive results from screening employs GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples with presumptive positivity are washed as needed. The comprehensive laboratory procedure, spanning from Accessioning to Confirmation, is evaluated in compliance with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can uncover drug use for as long as 90 days, unlike urine tests, which possess a reduced detection period.
• Difficulty to cheat: Cheating a hair drug test is extremely challenging, resulting in more reliable outcomes.
• Provides historical data: It supplies a chronic pattern of drug use across a period, beyond merely recent usage.

Limitations:

• Cannot detect recent use: Drugs require an estimated 5-7 days to become detectable within hair.
• Cost: Hair drug tests tend to be costlier compared to alternative drug testing techniques.
• Variations in results: Elements like hair color and personal hair growth differences can impact drug metabolite concentrations in hair.

Note: Although often termed as "hair follicle tests", the examination targets the hair strand 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.
