Hair Follicle Drug Testing - Coin, IA

What it is, How it works

Hair testing has emerged as an effective method for identifying the use of drugs and alcohol. It offers a long-term overview by embedding biomarkers in the strands as hair grows. When sampled near the root, hair provides a retrospective detection period for drugs and alcohol of up to about three months. It's easy to gather, hard to tamper with, and convenient to transport.

An ideal screening and confirmation sample requires a 1.5-inch section of roughly 200 hair strands (comparable to the thickness of a standard #2 pencil) near the scalp, totaling 100mg. For EtG testing, add-ons, or panels exceeding 10, 150mg is preferable. Using a jeweler's scale is suggested for measurement. If scalp hair is absent, equivalent body hair can be used. Note that "head hair" specifically refers to scalp hair, while "body hair" covers all other types (including facial and axillary).

Process Overview

The drug testing workflow in the lab comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is first entered into the laboratory system. This phase checks the sample’s seal and proper shipment, assigns a unique LAN (Laboratory Accessioning Number), and completes any outstanding data entry outside of an electronic chain of custody interface.

Screening offers an initial test for substances. Though cost-efficient for excluding drug presence in most samples, positive results from Screening must undergo confirmation for legal validity. Samples with presumptive positives during Screening proceed to secondary confirmation.

For presumptive positive samples in Screening, additional hair is taken from the initial sample for Extraction. Here, drugs are isolated from hair at concentrations much lower than alternative methods (such as urine or saliva), making hair screening a challenging approach.

Any positive results from Screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed as necessary before confirmation. The entire process, from Accessioning to Confirmation, is overseen under both the CAP (College of American Pathologists) Hair standards and accreditation per ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection range: Hair testing can recognize drug use for up to 90 days, unlike urine tests, which have a limited detection span.
• Challenging to manipulate: The reliability of hair drug tests makes them less susceptible to cheating.
• Captures historical trends: It provides a timeline of drug consumption, showing extended patterns instead of just current use.

Limitations:

• Inability to indicate recent drug use: Detection in hair takes approximately 5-7 days.
• Expense: Hair testing is typically costlier than alternative drug testing methods.
• Varying outcomes: Drug metabolite levels in hair can be influenced by hair color and growth rate differences.

Note: Although commonly termed "hair follicle tests," the test analyzes the actual hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle testing to traditional urine tests in Coin, IA, the former clearly stands out due to its superior detection accuracy and reliability. Hair tests can detect long-term drug use patterns, unlike urine tests that are limited to recent consumption.

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.
