Hair Follicle Drug Testing - Horseshoe Bay, TX

What it is, How it works

Hair analysis is now recognized as an effective method for detecting drug and alcohol usage. Hair captures biomarkers within the strands, offering a comprehensive timeline of substance use. When sampled near the scalp, hair can reveal drug or alcohol use over an estimated three-month period. Collecting hair is straightforward, relatively tamper-proof, and easy to transport.

A 1.5-inch segment of roughly 200 hair strands, similar in size to a #2 pencil, close to the scalp provides around 100mg, the optimal quantity for testing. For EtG, additional tests, and/or testing beyond 10 panels, 150mg is advisable. A jeweler’s scale is recommended for weighing the sample. If scalp hair cannot be obtained, an equivalent amount of body hair is acceptable. Note that "head hair" refers strictly to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).

Process Overview

Four primary stages comprise the laboratory processing of drug test outcomes: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial incorporation of a sample into the laboratory system, ensuring proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary additional data entry that the electronic chain of custody system does not provide.

Screening consists of a preliminary drug-of-abuse check. Although Screening effectively eliminates drug usage in most cases, positive results require confirmation to be considered legally acceptable. Samples showing presumptive positives in Screening need secondary confirmation.

If Screening suggests a positive, additional hair is extracted from the original sample and prepped for Extraction. In Extraction, drugs are drawn out from hair at a lower concentration than other methods (e.g., urine or oral fluid), which makes hair testing particularly challenging.

Any positive screening outcomes undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before Confirmation as necessary. The comprehensive laboratory procedure, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can reveal drug usage up to 90 days, contrasting with the shorter detection span of urine tests.
• Challenging to deceive: Cheating a hair drug test is significantly difficult, enhancing result accuracy.
• Shows historical patterns: The test can indicate ongoing drug use patterns, not just recent consumption.

Limitations:

• Incapable of identifying recent use: Drugs take about 5-7 days to become detectable in hair.
• Expense: Hair drug tests typically incur higher costs than other testing methods.
• Result variability: Hair color and individual differences in hair growth can impact drug metabolite concentrations in hair.

Note: While often labeled as "hair follicle tests", the test evaluates the hair shaft rather than the follicle beneath the skin.

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. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation. The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.

Clinical Applications of hair testing are witnessed by the insight on environmental tobacco smoke exposure, assessed by hair analysis in a population of students and the study of in utero-exposure to drugs of abuse through neonatal hair analysis. Exposure to drugs was also important in cases of child abuse/neglect, when the clinical purpose of hair testing merge with its forensic applications.
