Hair Follicle Drug Testing - Frost, TX

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drugs by embedding biomarkers within the fibers of the growing strand. When taken close to the scalp, hair offers around a 3-month timeframe for detecting alcohol and drugs. It's easy to collect, hard to tamper with, and simple to transport.

A 1.5-inch segment of roughly 200 hair strands (the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is optimal for analysis and confirmation. For EtG, additional tests, and/or panels exceeding 10, 150mg of the sample is advisable. Using a jeweler’s scale to weigh the sample is recommended. If scalp hair isn't available, a similar volume of body hair can be used. Head hair refers solely to scalp hair, while body hair includes all other types (facial, axillary, etc.).

Process Overview

The four primary phases in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves initial sample processing into a lab's system, including checking the sample's seal and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not available via an electronic chain of custody system.

Screening entails a preliminary quick check for drugs. While Screening effectively rules out drug use for most samples, a positive result requires confirmation to be legally admissible. Any samples showing a presumptive positive in Screening necessitate secondary confirmation.

If a sample is presumptively positive during Screening, additional hair is extracted from the initial sample and prepared for Extraction, where drugs are recovered from hair in much lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.

Any positive screening results are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation as needed. The entire lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug usage for up to 90 days, unlike urine tests with shorter detection spans.
• Hard to falsify: Cheating a hair drug test is notably challenging, thus enhancing result accuracy.
• Offers historical data: It displays drug use patterns over time, not merely recent use.

Limitations:

• Incapable of detecting recent use: Drugs take roughly 5-7 days to appear in hair.
• Expense: Hair drug tests generally cost more than other testing methods.
• Results variability: Factors such as hair color and individual differences in hair growth can influence the drug metabolite levels in hair.

Note: Though often termed as "hair follicle tests", the test evaluates 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.
