Hair Follicle Drug Testing - Peacock, TX

What it is, How it works

Hair analysis is increasingly recognized as a valuable means of detecting drug and alcohol consumption. The fibers of hair strands capture biomarkers, allowing for a comprehensive history of substance use over time. By using hair collected close to the scalp, it is possible to achieve a detection timeframe of up to approximately three months for substances such as alcohol. Hair is straightforward to collect, relatively secure from tampering, and convenient to transport.

A 1.5-inch section consisting of around 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp provides a 100mg sample, ideal for both screening and confirmation. For EtG, additional tests, or panels exceeding ten substances, a sample of 150mg is advised. We suggest using a jeweler's scale to weigh the sample. If scalp hair is insufficient, an equivalent amount of body hair can be collected. Reference to head hair pertains solely to scalp hair, while body hair includes all other types (such as facial and axillary hair).

Process Overview

The primary stages in laboratory processing of a drug test result involve Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial integration of a sample into the laboratory's system. This involves verifying that the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any data entry absent from an electronic chain of custody system.

Screening is an initial assessment for substances of concern. Though cost-effective for eliminating drug presence in many samples, a positive screen requires confirmation for legal admissibility. Any samples preliminarily positive during Screening demand a secondary confirmation.

Should a sample test preliminarily positive in the Screening phase, additional hair is extracted from the original specimen and prepared for Extraction. Here, substances are extracted from hair at notably lower concentrations than seen in alternative methods (e.g., urine or saliva), rendering hair drug screening a challenging process to execute.

Confirmation of any positive screening result employs methods such as GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo cleansing prior to confirmation as necessary. The entire laboratory sequence from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests offer a detection window of up to 90 days, surpassing the shorter timeframe of urine tests.
• Resistance to subversion: Cheating a hair drug test is exceedingly challenging, thereby enhancing result accuracy.
• Historical perspective: It provides a timeline of drug use over time rather than recent consumption alone.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair only after approximately 5-7 days have passed.
• Expense: Hair drug testing usually incurs higher costs than other testing methods.
• Result variability: Elements like hair color and individual growth rates can influence drug metabolite concentrations in hair.

Note: Despite the popular term "hair follicle tests", these tests evaluate the hair strand itself rather than the follicle located 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.
