Hair Follicle Drug Testing - Danielsville, GA

What it is, How it works

Hair screening is now recognized as an influential method for identifying drug and alcohol consumption. The hair retains a prolonged record of alcohol and other substances by embedding biomarkers within the fibers of the hair as it grows. When hair is collected near the scalp, it can reveal a detection span of up to around 90 days for alcohol and drugs. Hair is easy to gather, somewhat resistant to tampering, and simple to transport.

A 1.5-inch segment consisting of approximately 200 hairs (comparable to the girth of a #2 pencil) closest to the scalp provides 100mg of hair, which is the preferred quantity for analysis and confirmation. For EtG, additional tests, or those with more than 10 panels, 150mg of the sample is advised. We suggest weighing the sample on a jeweler’s scale. In instances where scalp hair is not present, an equivalent portion of body hair may be used. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other types of hair (facial, underarm, etc.).

Process Overview

Four primary stages are involved in the lab processing of a drug test: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initiation of a sample's processing into the lab's system. This ensures the sample was correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data entry absent from an electronic chain of custody system.

Screening conducts an initial rapid assessment for illicit drug usage. While Screening is a cost-effective method to negate drug usage for most samples, a positive screening necessitates verification to be valid in a legal context. Any samples shown as presumptively positive during Screening require further confirmation.

If Screening indicates a presumptive positive, more hair is extracted from the initial sample and prepped for Extraction. Here, drugs are isolated from hair at concentrations lower than other techniques (e.g., urine or saliva), rendering hair drug screening a challenging process.

Validation of any positive screening is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleansed before confirmation when needed. The complete lab process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 certification.

Advantages of hair drug testing:

• Extended detection duration: Hair drug evaluations can uncover drug use for up to 90 days, unlike urine examinations, which offer a briefer detection period.
• Difficulty to manipulate: It is extremely challenging to manipulate a hair drug test, thus enhancing the precision of the results.
• Delivers historical insights: It can reveal a pattern of drug usage across a span of time, not merely recent activity.

Limitations:

• Inability to identify recent use: Detection in hair takes around 5-7 days post-consumption.
• Expense: Hair drug tests tend to be costlier than other drug testing approaches.
• Result variability: Elements such as hair color and personal differences in hair growth can influence the levels of drug metabolites in hair.

Note: Although often called "hair follicle tests", the actual test examines the hair strand rather than the follicle below 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.

The legal framework surrounding hair testing and the achievement of guidelines to ensure fairness, accuracy, and confidentiality in drug testing practices have also been discussed,and the SoHT consensus on general hair testing and testing for drugs of abuse was presented at the meeting and published as a Letter to the Editor.

In conclusion, the special issue of Drug Testing and Analysis, featuring manuscripts from the SoHT–GTFI meeting in Verona 2022, reflects the remarkable advancements achieved in this field.
