Hair Follicle Drug Testing - Velda Village, MO

What it is, How it works

Hair analysis has become a significant resource for identifying drug and alcohol consumption. By encapsulating biomarkers within the fibers, hair offers an extensive timeline for detecting alcohol and other substances. Captured near the scalp, hair demonstrates a detection window stretching up to a 3-month period for alcohol and drugs. Collection is straightforward, modifying it is challenging, and transportation is simple.

A 1.5-inch section containing approximately 200 hair strands (roughly equivalent to a #2 pencil) from the scalp section ensures a 100mg hair collection, the preferred sample for screenings and verifications. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is preferred. Using a jeweler’s scale to weigh samples is advised. If scalp hair is unavailable, a similar volume of body hair can be utilized. References to head hair imply only scalp hair, while body hair encompasses all other forms (facial, axillary, etc.).

Process Overview

The laboratory procedures for drug test analysis encompass four principal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning starts with incorporating a sample into the laboratory’s system. This step confirms the sample's proper sealing and shipping, generates a random LAN (Laboratory Accessioning Number), and completes any missing data not inputted via an electronic chain of custody system.

Screening performs a preliminary check for drugs. Although cost-effective in excluding drug presence in most samples, a positive screen demands confirmation for legal acceptability. Any samples showing presumptively positive in Screening need further verification.

If Screening yields a presumptive positive, additional hair is retrieved from the initial sample for Extraction. During this phase, drugs are extracted at significantly reduced concentrations compared to other methods (e.g., urine or oral fluids), which is why hair drug screening stands as the most complex methodology to execute.

Any positive result from screening undergoes confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, presumptive positive samples are washed when necessary. The entire lab process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use up to 90 days, compared to the shorter timeframe of urine tests.
• Increased accuracy: Altering outcomes of a hair drug test is very challenging, ensuring more reliable results.
• Longitudinal data provision: It depicts a pattern of drug use over time rather than immediate use.

Limitations:

• Recent use detection: Detectability of drugs in hair typically takes about 5-7 days post-use.
• Expense: Hair drug tests often exceed costs of alternative testing methods.
• Result inconsistencies: Factors like hair color and personal growth rates may influence the concentration of drug metabolites in hair.

Note: Commonly labeled as "hair follicle tests", the examination targets the hair strand, not the follicle below 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.
