Hair Follicle Drug Testing - Center City, TX

What it is, How it works

Hair analysis is recognized as an effective approach for identifying drug and alcohol consumption. The hair captures long-term evidence of substances by enclosing biomarkers within the hair strand's fibers as it grows. When taken near the scalp, hair can reveal a timeframe of up to roughly 3 months for detecting drugs and alcohol. It's easy to collect, relatively resistant to tampering, and simple to send.

A sample measuring 1.5 inches and approximately 200 strands of hair (comparable to a #2 pencil) next to the scalp yields 100mg of hair, which is the optimal sample mass for tests and confirmations. For EtG, add-ons, or evaluations exceeding 10 panels, 150mg of hair is advisable. We suggest using a jeweler’s scale for weighing the sample. If head hair isn't accessible, an equivalent volume of body hair is an alternative. By “head hair,” we mean hair from the scalp exclusively, whereas “body hair” encompasses all other hair kinds (facial, axillary, among others).

Process Overview

The major phases in the laboratory testing process for drugs encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning concerns the initial integration of a specimen into a lab's framework. This ensures the sample was adequately sealed and sent, attaches a unique LAN (Laboratory Accessioning Number), and handles any supplementary data input not managed by an electronic chain of custody.

Screening involves a preliminary appraisal for drug presence. Although it’s a cost-efficient method for excluding drug use in most cases, any positive result during Screening must undergo confirmation to be court-admissible. Samples flagged as possibly positive in Screening necessitate a follow-up confirmation.

Should a sample receive a positive indication during Screening, additional hair is extracted from the original batch for Extraction. Here, drugs are isolated from the hair at far lower concentrations compared to other techniques (like urine or oral fluid), making hair drug analysis the most challenging technique.

Confirmation of any preliminary positive result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Every sample that's assumed positive is cleansed before confirmation as necessary. The complete lab procedure from Accessioning to Confirmation is conducted under both the CAP (College of American Pathologists) Hair categorization and the endorsement of ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Drug usage can be detected with hair tests up to 90 days, in contrast to urine tests with shorter windows.
• Hard to falsify: Cheating a hair drug test is nearly impossible, making the findings more reliable.
• Historical consumption patterns: It can reveal a timeline of drug use over an extended period, not merely recent intake.

Limitations:

• Can’t identify recent consumption: Drugs take about 5-7 days to become detectable in hair.
• Price: Hair drug testing often costs more than alternative methods.
• Result variability: Factors such as hair hue and individual hair growth can influence the drug metabolite concentrations in the hair.

Note: Despite being labeled as "hair follicle tests," the analysis involves the hair strand rather than 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.
