Hair Follicle Drug Testing - La Crosse, KS

What it is, How it works

Hair testing is regarded as an effective method for detecting drug and alcohol consumption. Hair serves as a long-term record of alcohol and drug exposure by embedding biomarkers within the fibers of the developing hair strand. When obtained near the scalp, hair can provide an approximate 3-month detection timeframe for alcohol and drugs. It's easy to collect hair, challenging to tamper with, and convenient to transport.

A sample of 1.5 inches in length containing roughly 200 hair strands (around the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal amount for analysis and confirmation. For EtG, enhancements, and/or examinations exceeding 10 panels, a 150mg specimen is advised. Using a jeweler’s scale is suggested to weigh the specimen. If scalp hair isn't available, an equivalent amount of body hair can be gathered. By head hair, we mean only scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The drug testing laboratory process involves four crucial steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial incorporation of a sample into a lab’s system. This process ensures the sample is sealed and shipped correctly, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any supplementary data entry missing from an electronic chain of custody system.

Screening conducts a preliminary drug abuse check. While cost-effective for discarding drug use in most samples, a positive result from Screening necessitates confirmation for legal acceptance. Samples with a presumptive positive in Screening must undergo further confirmation.

If a Screening stage sample is presumptively positive, additional hair is extracted from the initial sample for the Extraction stage. Here, drugs are removed from hair at a notably lower concentration than through other methods (e.g., urine or oral fluid), making hair drug testing a very challenging methodology.

Confirming a positive screening result utilizes GC/MS, GC/MS/MS or LC/MS/MS. As necessary, all presumptive positive samples undergo washing before confirmation. The comprehensive laboratory process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can reveal drug consumption over a span of up to 90 days, while urine tests cover a shorter period.
• Challenging to falsify: Cheating on a hair drug test is extremely difficult, thus ensuring greater accuracy in results.
• Retrospective usage pattern: It offers an insight into the drug use pattern over time, not just recent usage.

Limitations:

• Inability to detect recent usage: Drugs require about 5-7 days to become traceable in hair.
• Expense: Hair drug tests are typically pricier than other drug testing techniques.
• Result variability: Elements such as hair color and personal hair growth differences can influence drug metabolite concentrations in the hair.

Note: Although commonly called "hair follicle tests", the test actually analyzes the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

The decision to opt for hair follicle testing over urine testing in La Crosse, KS, lies in its superior detection capabilities.

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.
