Hair Follicle Drug Testing - London, OH

What it is, How it works

Hair testing is now regarded as a potent method for identifying drug and alcohol use. Hair can offer an extensive history of alcohol and drug usage by capturing biomarkers within its growing strands. When gathered near the scalp, hair can provide up to around a 3-month detection span for substances. Hair collection is straightforward, somewhat resistant to tampering, and convenient to ship.

A 1.5-inch portion comprising about 200 hair strands (comparable to the width of a #2 pencil) nearest to the scalp amounts to 100mg of hair, which is the optimal sample size for analysis and validation. For EtG, additional tests, and/or more than 10 panels, 150mg of the specimen is advisable. Measuring the specimen on a jeweler’s scale is recommended. If scalp hair is not accessible, a similar quantity of body hair can be gathered. By head hair, we mean only scalp hair. Body hair encompasses all other types, like facial, axillary, etc.

Process Overview

The laboratory processing of a drug test result is comprised of four principal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial entry of a sample into a lab's system. This process includes checking that the sample was securely sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any remaining data entry not provided through an electronic chain of custody system.

Screening involves an initial, rapid assessment for illicit drugs. Though Screening is an economical approach for excluding drug use in most samples, a positive result must be validated for it to be legally acceptable. Any samples flagged as presumptively positive in Screening necessitate a follow-up confirmation.

When a sample tests positive in the Screening phase, additional hair is extracted from the original specimen for the Extraction phase. During Extraction, drugs are removed from hair at a much lower concentration than other methods (like urine or saliva), which is why hair drug testing is among the most challenging processes to execute.

Positive results in Screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples testing presumptive positive undergo a pre-confirmation wash as needed. The complete laboratory procedure from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair category and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use over a 90-day period, unlike urine tests with a shorter timespan.
• Hard to manipulate: Cheating a hair drug test is extremely challenging, increasing result accuracy.
• Provides a history of usage: It delivers a timeline of drug use over an extended duration, beyond recent consumption.

Limitations:

• Inability to detect recent usage: Drugs become detectable in hair approximately 5-7 days after use.
• Expensive: Hair drug tests are typically costlier compared to other testing methods.
• Result variability: Factors like hair color and individual differences in hair growth can influence drug metabolite concentration in hair.

Note: Frequently referred to as "hair follicle tests," this test examines the hair strand, 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.
