Hair Follicle Drug Testing - Valparaiso, NE

What it is, How it works

Hair analysis has emerged as a robust means for identifying alcohol and drug consumption. Hair strands offer a prolonged record of substance usage by capturing biomarkers within the strands' fibers. When obtained near the scalp, hair can indicate a detection window spanning up to about three months for alcohol and other drugs. It is straightforward to gather, relatively challenging to alter, and simple to transport.

A hair sample measuring 1.5 inches from about 200 strands (similar to the girth of a #2 pencil) next to the scalp will yield 100mg, which is ideal for both screening and confirmation. For EtG, additional tests, and/or panels over 10, it is advisable to gather 150mg of hair. Using a jeweler’s scale is recommended for ensuring the correct weight. Should scalp hair be unavailable, an equivalent quantity of body hair might be used. By head hair, we mean only scalp hair. Body hair encompasses other types such as facial or axillary.

Process Overview

The drug testing protocol in the lab consists of four sequential steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is about initiating the sample into the lab’s framework. This step ensures the sample’s seal and shipment integrity, assigns a unique LAN (Laboratory Accessioning Number), and completes any data entry missing from an electronic custody system.

Screening provides a preliminary examination for drugs. Though it is a cost-effective technique to potentially exclude drug usage in most samples, any positive outcome must be confirmed for legal admissibility. All samples with a presumptive positive result in Screening must undergo an additional confirmation.

For samples with a presumptive positive in Screening, additional hair is extracted from the original sample for Extraction. At this stage, drug extraction from hair occurs at a significantly lower concentration than other methods (like urine or oral fluid), making hair drug screening a challenging procedure.

Confirmation for any positive in Screening is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. Necessary preparations, like washing presumptive positive samples, are performed before confirmation. The complete lab process from Accessioning to Confirmation complies with both the CAP (College of American Pathologists) Hair designation and accreditation for ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, which is longer than the window offered by urine tests.
• Hard to manipulate: Cheating on a hair drug test is extremely difficult, enhancing result reliability.
• Chronological insights: Provides insight into drug use patterns over time, rather than just recent usage.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug tests tend to cost more than other drug detection methods.
• Variation potential: Hair growth rate and color, along with individual differences, can impact drug metabolite concentration in hair.

Note: Despite often being called "hair follicle tests", the actual analysis targets the hair strand itself, not 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.
