Hair Follicle Drug Testing - Pleasanton, NM

What it is, How it works

Viewed as a strong instrument, hair testing effectively identifies alcohol and drug usage. Hair records a prolonged history of these substances by embedding biomarkers into the hair strand's fibers as it grows. When sampled close to the scalp, hair can offer a detection range of up to around three months for alcohol and drugs. Hair is easy to collect, somewhat hard to tamper with, and simple to transport.

A 1.5-inch piece comprising approximately 200 hair strands (about the diameter of a #2 pencil) nearest to the scalp delivers 100mg of hair, which is the preferred specimen size for both screening and confirmation. For EtG, add-ons, or panels exceeding 10 tests, a specimen of 150mg is advised. It is suggested to weigh the sample using a jeweler's scale. Should scalp hair be inaccessible, the equivalent volume of body hair can be gathered. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test is composed of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers incorporating a sample into a lab's system. This step involves confirming the sample’s proper sealing and shipment, generating a random LAN (Laboratory Accessioning Number), and completing any leftover data entry not handled by an electronic chain of custody framework.

Screening provides an initial rapid evaluation for potential drug abuse. While this step offers a cost-efficient means to dismiss drug use in the majority of cases, a positive screen necessitates confirmation to be legally admissible. Samples yielding a presumptive positive in Screening need secondary confirmation.

For samples testing presumptively positive at the Screening phase, additional hair is extracted from the original specimen for preparation during the Extraction phase. During this step, substances are isolated from hair at much lower concentrations compared to other methods (ex. urine or oral fluid); hence, hair drug testing stands as the most complex method to conduct.

Confirmation for any positive screening outcome occurs through GC/MS, GC/MS/MS, or LC/MS/MS. If required, all presumptive positive specimens are washed prior to confirmation. The comprehensive lab process from Accessioning through Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and accreditation adhering to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests reveal drug consumption over as much as 90 days, distinct from urine tests which have a reduced detection duration.
• Hard to manipulate: Cheating a hair drug test is notably challenging, enhancing result accuracy.
• Yields historical insights: It highlights patterns of drug activity over time, instead of just indicating recent usage.

Limitations:

• Incapable of detecting immediate use: Drugs become traceable in hair roughly 5-7 days post-consumption.
• Expense: Hair drug tests typically incur higher costs compared to other drug testing techniques.
• Result variability: Factors like hair color and personal hair growth differences can influence drug metabolite concentrations in hair.

Note: Termed often as "hair follicle tests," the examination 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. 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.
