Hair Follicle Drug Testing - Flora Vista, NM

What it is, How it works

Hair analysis is recognized as a robust method for detecting drug and alcohol usage. It offers a prolonged history of drug and alcohol consumption by capturing biomarkers in the hair fiber as it grows. When taken close to the scalp, hair can reveal alcohol and drug use up to an estimated three-month period. Hair is easy to collect, somewhat resistant to tampering, and convenient to transport.

A hair sample measuring 1.5 inches in length and comprising about 200 hairs (approximately the size of a #2 pencil) near the scalp yields 100mg, the optimal quantity for both screening and confirmation procedures. For EtG, additional analyses, or tests exceeding 10 panels, 150mg of the sample is suggested. It is advisable to measure the sample's weight using a jeweler’s scale. If scalp hair cannot be used, a similar volume of body hair is acceptable. When discussing head hair, only scalp hair is considered. Body hair encompasses all other hair, such as facial and axillary.

Process Summary

The laboratory process for a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial integration of a sample into the lab's system, including ensuring the sample is properly sealed and transported, issuing a unique LAN (Laboratory Accessioning Number), and inputting additional data not captured by an electronic chain of custody framework.

Screening provides a preliminary assessment for substances of abuse. Though cost-effective for negating drug use in most samples, a positive screening requires confirmation for legal acceptability. Any screenings with presumptive positives necessitate further confirmation.

If a screening reveals a presumptive positive, additional hair is extracted from the initial sample for the Extraction phase. This step isolates drugs from hair at significantly lower concentrations than other methods (e.g., urine or saliva), emphasizing the complexity of hair drug testing.

GC/MS, GC/MS/MS, or LC/MS/MS is employed to validate any positive screening outcomes. Presumptively positive samples undergo washing, as warranted, prior to confirmation. The complete laboratory workflow, from Accessioning through Confirmation, is examined under both the CAP (College of American Pathologists) Hair categorization and adherence to ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection: Hair drug assessments can trace drug usage up to 90 days, whereas urine tests have a more limited timeframe.
• Hard to falsify: Manipulating results in a hair drug test is challenging, ensuring greater accuracy.
• Historical insights: It captures a drug usage pattern over time, not just recent activity.

Drawbacks:

• Inability to detect recent use: Drugs become discernible in hair only after approximately 5-7 days.
• Expense: Hair drug tests generally incur higher costs compared to other testing techniques.
• Result variations: Elements such as hair color and personal growth rates can influence drug metabolite levels in hair.

Note: While termed "hair follicle tests", the test is conducted on the hair strand, not the follicle beneath 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.
