Hair Follicle Drug Testing - Church Hill, MD

What it is, How it works

The recognition of hair testing has grown as a vital method for identifying drug and alcohol consumption. It offers a comprehensive history of substance use by embedding biomarkers within hair strand fibers. Sampling hair near the scalp can reveal drug and alcohol use for about three months. Hair is easy to gather, challenging to tamper with, and convenient for shipping.

A collection of a 1.5-inch portion consisting of around 200 hair strands (similar in size to a #2 pencil) from close to the scalp can yield 100mg of hair, perfect for both screening and confirmation. For testing such as EtG, additional requirements, or panels exceeding 10, a specimen weight of 150mg is suggested. It is advisable to weigh specimens using a jeweler's scale. In cases where head hair is absent, a comparable weight of body hair is acceptable. Head hair exclusively refers to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of drug test results includes four steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step where the sample is processed into the lab's system. This step ensures the sample's seal and shipment integrity, assigns a unique LAN (Laboratory Accessioning Number), and completes any remaining data entries absent in an electronic chain of custody system.

Screening conducts a preliminary evaluation to detect drug abuse. Though Screening efficiently rules out drug use in most cases, positive results require confirmation for legal credibility. Samples indicating preliminary positivity must undergo further confirmation.

Samples marked as presumptively positive during Screening undergo further specimen extraction. Drugs are extracted from hair at lower concentrations compared to other methods such as urine or oral fluid testing, making hair drug screening the most intricate method to conduct.

GC/MS, GC/MS/MS, or LC/MS/MS techniques are employed to confirm positive Screening results. Presumptive positive samples are washed before confirmation as necessary. The comprehensive review of the laboratory processing, from Accessioning to Confirmation, complies with both CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can uncover drug use for up to 90 days, surpassing urine tests which have a shorter span.
• Increased accuracy: Hair drug tests are difficult to tamper with, enhancing result reliability.
• Historic data: They provide a timeline of drug use rather than just recent occurrences.

Limitations:

• Recent use undetectable: It takes about 5-7 days before drugs become traceable in hair strands.
• Higher cost: Hair drug tests typically cost more than other testing techniques.
• Result variability: Factors like hair color and individual growth differences can influence drug metabolite concentration in hair.

Note: Although commonly known as "hair follicle tests", these tests examine the hair strand, 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.
