Hair Follicle Drug Testing - Mountain Road, VA

What it is, How it works

Hair analysis is seen as an effective means for identifying drug and alcohol consumption. Hair strands provide extended insight into the history of substance use, as they store biomarkers within the strands. When collected near the scalp, hair offers a detection period of up to about three months for alcohol and other substances. The collection process for hair is straightforward, making it less susceptible to tampering and convenient for transportation.

For an ideal screening and confirmation sample, a 1.5-inch section of around 200 hair strands (approximately the diameter of a #2 pencil) nearest the scalp is needed to obtain 100mg of hair. For EtG tests, additional analyses, or tests beyond 10 panels, a 150mg sample is suggested. Using a jeweler’s scale for weighing the specimen is advisable. If scalp hair is not available, a similar quantity of body hair is acceptable. Head hair refers solely to scalp hair, whereas body hair encompasses all other types of hair (such as facial and axillary hair).

Process Overview

The laboratory analysis of a drug test result is comprised of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary stage where the sample is integrated into the laboratory's system. This step includes ensuring the sample was appropriately sealed and transported, generating a unique LAN (Laboratory Accessioning Number), and finishing any supplementary data entry that the electronic chain of custody system hasn't provided.

Screening is a preliminary assessment for potential drug use. Even though Screening is an economical approach to exclude drug usage in most samples, a positive Screen must be substantiated to be legally accepted. Every sample that tests positive in the Screening phase necessitates further confirmation.

Should a sample test positive in the Screening stage, additional hair is taken from the original sample for the Extraction phase. This phase involves extracting drugs from hair at significantly lower concentrations compared to other methods (e.g., urine or saliva), highlighting the complexity of performing hair drug screening.

To confirm any positive Screening result, procedures like GC/MS, GC/MS/MS, or LC/MS/MS are employed. All samples that test presumptive positive undergo washing before Confirmation if needed. The entire lab process, from Accessioning to Confirmation, is evaluated according to both CAP (College of American Pathologists) Hair standards and the ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to 90 days prior, whereas urine tests have a shorter window.
• Resistance to cheating: The integrity of a hair drug test is robust, leading to more reliable results.
• Shows a usage pattern: It reveals a trend of substance use over time instead of only recent activities.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair after about 5-7 days.
• Higher costs: Hair drug tests typically cost more than alternative testing methods.
• Variable outcomes: Differences like hair color and individual hair growth rates might impact drug metabolite concentrations within hair.

Note: Although frequently termed "hair follicle tests", these tests examine 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented.
