Hair Follicle Drug Testing - Dargan, MD

What it is, How it works

Considered a robust method, hair testing is effective for identifying drug and alcohol consumption. The hair captures biomarkers in its fibers, offering an extended history of substance use. When gathered near the scalp, hair can reveal alcohol and drug consumption over a period of roughly three months. It's easy to collect, resists tampering, and is simple to ship.

A sample of 1.5 inches comprising around 200 strands close to the scalp yields 100mg, which is optimal for both screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, it is advisable to collect 150mg. We suggest using a jeweler's scale for accuracy. In the absence of scalp hair, a similar amount of body hair may be used. Our reference to head hair pertains specifically to scalp hair. Body hair covers all other types (e.g., facial, axillary).

Process Overview

The drug test result processing in laboratories consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially processed into the lab’s system. This stage certifies the sample as properly sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and finalizes any remaining data entry outside the electronic chain of custody system.

Screening provides an initial swift assessment for drug use. Although cost-effective for ruling out drug presence in most samples, confirming a positive Screening result is necessary for courtroom acceptance. Samples testing positive in Screening necessitate additional confirmation.

If a sample tests positive during Screening, additional hair is taken from the original sample for Extraction. Here, drugs are isolated from hair at lower levels of concentration compared to other techniques (ex. urine or oral fluid), making hair drug screening the most challenging methodology to conduct.

To confirm a positive screening outcome, procedures using GC/MS, GC/MS/MS, or LC/MS/MS are executed. Prior to confirmation, all positive samples undergo washing as required. The complete laboratory process from Accessioning through to Confirmation is assessed under both the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Allows for drug use detection extending up to 90 days, unlike the shorter detection period of urine tests.
• Difficult to manipulate: Cheating on a hair drug test is notably challenging, enhancing result accuracy.
• Reveals usage patterns: Offers insight into drug consumption over time rather than merely recent use.

Limitations:

• Recent use undetectable: Drugs become detectable in hair only after about 5-7 days.
• Expense: Comparatively more costly than alternative drug testing methods.
• Result variability: Hair color and personal growth differences may influence drug metabolite levels in hair.

Note: The term "hair follicle tests" often misrepresents the procedure, which analyzes the hair strand and 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.

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. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
