Hair Follicle Drug Testing - Round Top, TX

What it is, How it works

The utilization of hair testing has evolved into an effective means for identifying drug and alcohol consumption. Hair offers a prolonged timeline of alcohol and drug use by capturing biomarkers within the fibers of the developing hair strand. When sampled near the scalp, hair can reveal a detection window of up to roughly three months for alcohol and drugs. It is straightforward to collect, relatively challenging to tamper with, and straightforward to transport.

A 1.5-inch section of around 200 hair strands (roughly the diameter of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal quantity for screening and verification. For EtG, additional tests, and/or panels exceeding 10, 150mg of the sample is advised. We suggest using a jeweler’s scale for weighing the specimen. If scalp hair is not available, a comparable amount of body hair can be collected. When we mention head hair, we mean scalp hair exclusively. Body hair refers to all other hair categories (facial, axillary, etc.).

Process Overview

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

Accessioning entails the preliminary processing of a sample into a lab’s system. This encompasses confirming the sample was properly sealed and sent, assigning a random Laboratory Accessioning Number (LAN), and completing any extra data entry not covered by an electronic chain of custody system.

Screening involves an initial rapid check for illicit drug usage. Although Screening offers a cost-effective approach to exclude drug use for most samples, a positive screen must be verified for court admissibility. Samples that are presumptively positive in Screening require a subsequent confirmation.

If a sample tests presumptively positive in Screening, additional hair is extracted from the initial sample and readied for Extraction. During this phase, drugs are extracted from hair at a concentration much lower than in other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to perform.

Confirmation of any positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive are washed before confirmation as necessary. The entire laboratory process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests can identify drug use for as long as 90 days, unlike urine tests which have a shorter detection span.
• Cheat resistance: It is exceedingly difficult to manipulate a hair drug test, enhancing result accuracy.
• Offers historical data: It illustrates a pattern of drug use over time, rather than just recent consumption.

Limitations:

• Incapable of identifying recent use: Drugs take approximately 5-7 days to become detectable in hair.
• Expense: Hair drug tests generally carry a higher cost than other drug testing methods.
• Result variations: Variables like hair color and personal hair growth variations can influence drug metabolite concentration in hair.

Note: Although often called "hair follicle tests", the analysis targets the hair strand itself, 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.
