Hair Follicle Drug Testing - Gilmore, MD

What it is, How it works

Hair testing has become recognized as a robust method for identifying drug and alcohol consumption. Hair offers an extended historical record of alcohol and drugs by encasing biomarkers within the strands of hair as it grows. When taken from near the scalp, hair can give a detection period of up to roughly three months for alcohol and drugs. Hair is easy to collect, tougher to tamper with, and straightforward to ship.

A 1.5-inch section of roughly 200 hair strands (comparable to the diameter of a #2 pencil) taken nearest to the scalp provides 100mg of hair, which is the optimal sample for screening and confirmation tests. For EtG, additional tests, or tests exceeding 10 panels, 150mg of the sample is advised. It is advisable to weigh the sample using a jeweler's scale. If scalp hair cannot be obtained, a similar amount of body hair may be used. When mentioning head hair, we only mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the phase of entering a sample into a lab's system. It ensures the sample was sealed and sent correctly, assigns a random LAN (Laboratory Accessioning Number), and finishes any extra data entry not covered by an electronic chain of custody setup.

Screening is a preliminary quick procedure for identifying drugs of abuse. Although Screening is a cost-efficient means to rule out drug usage in most samples, a positive screening needs confirmation to be suitable for court. Samples that are presumptive positives in Screening require a second confirmation.

If a sample is presumptive positive at the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. This stage involves extracting drugs from hair at much lower concentrations than other methods (e.g., urine or oral fluid), which makes hair drug testing the most intricate methodology to perform.

Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if needed. The full laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug usage for as long as 90 days, unlike urine tests which have a shorter timeframe.
• Difficult to manipulate: Cheating a hair drug test is quite challenging, ensuring more precise results.
• Offers historical insight: It supplies a pattern of drug consumption over a timeline, beyond just recent use.

Limitations:

• Incapable of recent use detection: It needs about 5-7 days for drugs to become noticeable in hair.
• Expense: Hair drug tests typically have a higher price than other methods of drug testing.
• Result variability: Aspects like hair color and individual differences in hair growth can influence drug metabolite concentrations in hair.

Note: While often referred to as "hair follicle tests", the analysis focuses on 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.
