Hair Follicle Drug Testing - Oklahoma City, OK

What it is, How it works

Hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. Hair encapsulates a prolonged record of alcohol and drug intake by embedding biomarkers in the strands' fibers as they grow. When sourced near the scalp, hair can reveal a detection window stretching up to about three months for alcohol and drugs. Hair collection is straightforward, relatively tamper-proof, and convenient to send.

A 1.5-inch section consisting of around 200 hair strands, roughly akin to a #2 pencil’s thickness, nearest to the scalp yields 100mg of hair, which is prime for analysis and verification. For EtG extensions and tests exceeding 10 panels, 150mg of the sample is suggested. Employ a jeweler's scale for accurate specimen measuring. If scalp hair is unavailable, a similar volume of body hair is an alternative. When discussing head hair, it refers strictly to scalp hair, while body hair encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

The laboratory procedure for processing a drug test result comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning integrates the sample into a laboratory's system, ensuring that the specimen was properly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any outstanding data input not covered by an automated chain of custody setup.

Screening entails an initial, rapid assessment for drugs of abuse. While cost-effective, Screening primarily eliminates drug usage in most samples, a positive result necessitates confirmation for legal viability. Samples that appear positive in Screening must undergo a secondary confirmation.

Should a sample prove presumptively positive in the Screening phase, additional hair is taken from the original specimen for Extraction. Here, drugs are extracted from hair at significantly lower concentrations than in alternative methods (like urine or oral fluid), which is why hair drug screening poses the greatest challenge among methodologies.

Confirmation for any positive screening result is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples showing presumptive positives undergo cleansing as needed. Each phase, from Accessioning to Confirmation, is reviewed according to both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests identify drug usage up to 90 days, unlike urine tests with a shorter detection range.
• High difficulty to tamper: Cheating on a hair drug test is extremely challenging, leading to more reliable results.
• Historical consumption data: It offers insights into drug usage patterns over time, rather than just recent interaction.

Limitations:

• Inability to detect recent use: It requires approximately 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug testing typically incurs higher costs compared to other testing forms.
• Result variations: Elements like hair color and individual hair growth disparities can influence drug metabolite concentrations in hair.

Note: Although often termed as "hair follicle tests," the assessment examines the hair strand and 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.

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.
