Hair Follicle Drug Testing - Whitesville, KY

What it is, How it works

Hair analysis has emerged as an effective means of identifying drug and alcohol consumption. Hair can chronicle a prolonged history of substance exposure by embedding biomarkers in its growing strands. When procured near the scalp, it offers an estimated three-month span for detecting drugs and alcohol. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A sample of 1.5 inches, comprising approximately 200 hair strands (about the thickness of a #2 pencil) near the scalp, yields 100mg of hair, ideal for testing purposes. For EtG, additional tests, and/or examinations beyond 10 panels, 150mg of the specimen is preferred. The use of a jeweler’s scale for measuring the specimen is suggested. In cases where scalp hair is not obtainable, a comparable quantity of body hair might be gathered. Head hair refers solely to scalp hair, whereas body hair includes all other types (facial, axillary, etc.).

Procedure Summary

The four essential phases in laboratory drug testing are Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the early integration of a sample into a laboratory's system. This encompasses ensuring that the sample has been appropriately sealed and dispatched, allotting a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data input absent from an electronic chain of custody.

Screening involves an initial rapid assessment for illicit substances. While it provides a cost-efficient approach to exonerate the majority of samples from drug usage, any positive screening must be substantiated for legal acceptance. Samples that display presumptive positivity during Screening necessitate a subsequent confirmation.

For samples flagged as presumptive positives during Screening, additional hair is drawn from the initial sample for the Extraction phase. This involves extracting the substances from the hair at significantly lower concentrations than other techniques (such as urine or oral fluid), underscoring the complexity of hair drug screening.

Confirmation of positive screening outcomes is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo a wash before confirmation, if necessary. The entire laboratory protocol from Accessioning through Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Benefits of hair drug examinations:

• Extended detection period: Hair tests identify drug consumption for up to 90 days, while urine tests have briefer detection spans.
• Challenge to deceive: The integrity of hair tests makes altering results exceptionally difficult, enhancing accuracy.
• Historical record: It offers insight into a pattern of substance use over time, not solely current usage.

Drawbacks:

• Lack of recent use detection: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Generally, hair examinations have a higher cost compared to other testing methods.
• Result variability: Differences in hair color and individual growth rates can influence drug metabolite concentrations in hair.

Note: While commonly termed "hair follicle tests", the analysis targets the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Whitesville, KY, hair follicle tests surpass urine tests by offering exceptional detection accuracy.

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.
