Hair Follicle Drug Testing - Liberty Hill, LA

What it is, How it works

Hair assessments have emerged as a robust method for detecting substance and alcohol consumption. By capturing biomarkers within the hair’s growing strands, hair offers an extended history of alcohol and drug use. When samples are taken near the scalp, it can reveal drug and alcohol use for up to roughly three months. Hair collection is straightforward, relatively tamper-resistant, and easy to transport.

A sample of 1.5 inches containing around 200 strands (comparable to the thickness of a #2 pencil) from the scalp yields 100mg, the perfect sample size for both preliminary and confirmatory analysis. For EtG evaluations and tests exceeding 10 panels, 150mg of hair is advisable. Utilizing a jeweler's scale to measure the specimen's weight is recommended. In the absence of scalp hair, an equivalent amount of body hair is acceptable. References to head hair denote scalp hair, while body hair encompasses all other types such as facial or axillary hair.

Process Overview

The laboratory processing of a drug test result encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves integrating the sample into the lab's system, ensuring proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any additional data input absent from an electronic chain of custody.

Screening is an efficient initial analysis to identify misuse of substances. Though Screening can economically rule out drug consumption in many samples, a confirmed result is essential for legal proceedings. Positive screenings necessitate further confirmation.

In cases of potential positivity during Screening, additional hair is extracted for the Extraction phase. Drugs are drawn from hair at a lower concentration than with urine or oral fluid tests, which contributes to the complexity of hair drug screening.

Confirmation of any positive Screening outcome uses GC/MS, GC/MS/MS, or LC/MS/MS techniques. All suspected positive samples undergo a wash prior to confirmation when necessary. The laboratory process, from Accessioning to Confirmation, aligns with CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use over a span of 90 days, as opposed to the shorter range of urine tests.
• Hard to evade: Cheating a hair drug test is challenging, ensuring greater accuracy.
• Provides usage history: It offers a timeline of drug use, not just recent consumption.

Limitations:

• Not for recent detection: Drugs become detectable in hair after around 5-7 days.
• Expense: Hair drug tests generally incur higher costs than alternative methods.
• Result variability: Hair color and growth differences may impact drug metabolite concentrations in hair.

Note: Often referred to as "hair follicle tests", these tests examine the hair strand, not the scalp's hair follicle.

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. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.

Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols.
