Hair Follicle Drug Testing - Howells, NE

What it is, How it works

Hair analysis is recognized as a potent method for identifying drug and alcohol consumption. Hair offers an extensive timeline of alcohol and drug usage by embedding biomarkers within the strands as they grow. When taken near the scalp, hair can present up to a roughly 3-month period of detection for alcohol and drugs. Collecting hair is straightforward, relatively challenging to tamper with, and easy for shipping.

A 1.5-inch segment of about 200 hair strands (similar in size to a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal sample for screening and confirmation. For EtG, extensions, or tests beyond 10 panels, 150mg of the sample is suggested. It is advisable to measure the sample using a jeweler’s scale. If scalp hair is not accessible, a similar quantity of body hair can be used. When referencing head hair, it pertains solely to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The procedure for processing drug test results in the laboratory involves four essential stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the sample's initial incorporation into a laboratory's system. This step includes ensuring that the sample was sealed and dispatched correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any missing data not supplied by an electronic chain of custody system.

Screening offers a preliminary assessment for drug abuse. While it is a cost-effective method to exclude drug use in the majority of samples, any favorable screen must be confirmed to be acceptable in legal settings. Any samples that test positive during Screening require additional verification.

Should a sample appear positive in the Screening phase, extra hair is extracted from the original sample and prepared for Extraction. In this phase, drugs are extracted from hair at much lower concentrations compared to other techniques (such as urine or oral fluid), hence hair drug screening ranks as the most intricate methodology.

Confirming any positive screening result utilizes GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation if necessary. The entire laboratory process from Accessioning to Confirmation is checked under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can reveal drug usage up to 90 days, unlike urine tests, which offer a shorter detection period.
• Difficulty to cheat: It is incredibly challenging to manipulate a hair drug test, ensuring more precise results.
• Provides historical data: It provides a trajectory of drug use over time, unlike just identifying recent consumption.

Limitations:

• Cannot detect recent use: It requires about 5-7 days for drugs to become noticeable in hair.
• Cost: Hair drug tests are typically pricier than other drug testing approaches.
• Variations in results: Elements like hair color and personal differences in hair growth can influence drug metabolite levels in hair.

Note: While commonly called "hair follicle tests", the analysis targets the hair strand rather than the hair 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.

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.
