Hair Follicle Drug Testing - Santa Teresa, NM

What it is, How it works

Hair testing is now recognized as a potent means for identifying drug and alcohol consumption. Hair encases a prolonged record of alcohol and drug usage by capturing biomarkers within its growing strands. When hair is collected near the scalp, it offers nearly a 3-month period for detecting alcohol and other drugs. Collection is straightforward, it's reasonably hard to tamper with, and shipping is convenient.

An ideal sample of around 200 strands of hair measuring 1.5 inches, typically the width of a #2 pencil, near the scalp is needed to provide 100mg of hair for analysis. For EtG, enhancements, and/or tests exceeding 10 panels, 150mg of the sample is advised. Using a jeweler’s scale is recommended to weigh the hair sample accurately. In cases where scalp hair cannot be obtained, a similar quantity of body hair may be used instead. "Head hair" specifically means scalp hair. "Body hair" encompasses other hair types (facial, axillary, etc.).

Process Overview

The processing of a drug test result in a lab involves Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initiation of sample processing within the lab’s system. It includes checking that the sample is sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry beyond what's provided by an electronic chain of custody system.

Screening does a swift initial check for drugs of abuse. While cost-efficient for eliminating drugs in most samples, Screening requires confirmation for a positive result to be court-valid. Samples found presumptively positive in Screening need further confirmation.

When Screening suggests a positive result, additional hair from the sample is extracted for further processing. In the Extraction stage, drugs are extracted from the hair at a lower concentration compared to other methods (like urine or oral fluid), making hair drug screening a complex process to carry out.

GC/MS, GC/MS/MS, or LC/MS/MS methods confirm any positive results initially detected during Screening. Presumptive positive samples undergo washing before confirmation if needed. The entire lab process from Accessioning to Confirmation is vetted under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests detect drug usage for up to 90 days, whereas urine tests have a more limited detection period.
• Resistant to tampering: Cheating a hair drug test is very difficult, resulting in more reliable outcomes.
• Historical insights: It provides an overview of drug use over time, rather than just recent usage.

Limitations:

• Doesn't spot recent use: Drugs take about 5-7 days to show up in hair tests.
• Costly: Hair drug tests usually cost more than other testing methods.
• Result variations: Hair color and individual hair growth differences can influence the levels of drug metabolites in the hair.

Note: Though often labeled as "hair follicle tests," the test actually evaluates the hair strand, not the follicle under the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
