Hair Follicle Drug Testing - Crystal Hill, VA

What it is, How it works

Hair analysis is now regarded as a significant method for identifying drug and alcohol consumption. By capturing biomarkers in the strands of growing hair, it provides a prolonged timeline of substance use. When cut close to the scalp, hair can offer roughly a 3-month detection period for drugs and alcohol. Hair collection is straightforward, fairly resistant to tampering, and easily shipped.

A 1.5-inch segment of roughly 200 hair strands (around the diameter of a #2 pencil) nearest to the scalp yields 100mg, ideal for testing and validation. For EtG, additives, and/or panels exceeding 10, a 150mg sample is advisable. We suggest using a jeweler’s scale for weighing. If scalp hair is not present, an equivalent quantity of body hair can be gathered. When referencing head hair, it pertains specifically to scalp hair. Body hair denotes all other hair varieties (facial, axillary, etc.).

Process Overview

The laboratory analysis of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the sample's initial integration into the lab’s system, ensuring it was sealed and transported correctly, assigning an arbitrary LAN (Laboratory Accessioning Number), and finalizing any extra data entry not supplied by an electronic chain of custody system.

Screening involves an initial swift evaluation for drugs of abuse. Although Screening is cost-efficient for excluding drug presence in most samples, a positive screen requires confirmation for legal admissibility. Any samples that return a presumptive positive in Screening necessitate further confirmation.

If a sample tests presumptive positive during Screening, additional hair is extracted from the initial sample for Extraction. During Extraction, drugs are removed from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), which is why hair drug screening is the most challenging method to conduct.

Confirmation for any screen-positive result is accomplished via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed prior to confirmation as necessary. The entire laboratory process from Accessioning to Confirmation is examined according to both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug consumption for as long as 90 days, unlike urine tests which have a brief detection timeframe.
• Challenging to deceive: Hair drug tests present significant difficulty in manipulation, ensuring more reliable outcomes.
• Offers historical insight: This method reveals a pattern of drug use over time, not just recent intake.

Limitations:

• Inability to detect recent ingestion: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug tests generally incur higher costs than other testing methods.
• Result disparities: Variables like hair color and personal differences in hair growth can influence drug metabolite concentrations in the hair.

Note: Although referred to as "hair follicle tests", the analysis targets the hair strand rather than 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.
