Hair Follicle Drug Testing - Tampico, WA

What it is, How it works

Seen as an impactful method for identifying drug and alcohol use, hair testing captures long-term usage by embedding biomarkers within the fibers of hair strands as they grow. When taken close to the scalp, hair samples can offer a detection window reaching up to about 3 months for alcohol and drugs. The collection process is straightforward, tampering is challenging, and shipment is convenient.

A 1.5-inch segment of roughly 200 hair strands (around the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal amount for screening and validation. For tests like EtG, add-ons, and those exceeding 10 panels, 150mg of the sample is advised. It's recommended to weigh the specimen using a jeweler’s scale. Should scalp hair be unavailable, a comparable quantity of body hair may be gathered. References to head hair pertain solely to scalp hair, whereas body hair encompasses all other types (such as facial and axillary hair).

Process Overview

The laboratory processing of drug test outcomes involves four essential stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the primary incorporation of a sample into the lab's records. This process verifies proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data input not included by an electronic chain of custody system.

During Screening, samples undergo an initial swift analysis for abusive drug presence. Although cost-efficient for excluding drug usage in most samples, a positive screen result necessitates confirmation for legal admissibility. Any samples flagged as positive in Screening must undergo a secondary verification.

For samples with presumptive positive results in Screening, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are drawn from hair at significantly reduced concentrations compared to other methods (e.g., urine or oral fluid), emphasizing the complexity of hair drug screening as a method.

Confirmation of any positive Screening result occurs using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation as needed. The entire lab cycle from Accessioning to Confirmation sees oversight under the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which offer a more limited detection period.
• Challenging to tamper with: It's exceedingly tough to circumvent a hair drug test, contributing to more reliable results.
• Historical drug use data: Provides insight into drug use patterns over an extended timeframe, beyond just recent consumption.

Limitations:

• Inability to detect recent use: Drugs require about 5-7 days to be traceable in hair.
• Expense: Hair drug testing tends to be pricier than other drug testing techniques.
• Result variability: Elements like hair color and personal hair growth differences may influence drug metabolite concentration in hair.

Note: Often referred to as "hair follicle tests," the analysis actually focuses on the hair strand, not the hair 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.
