Hair Follicle Drug Testing - James City, NC

What it is, How it works

Hair testing is regarded as an effective instrument for identifying drug and alcohol consumption. Hair captures biomarkers within its fibers, providing a long-term record of alcohol and drug use. When harvested near the scalp, hair can offer a detection period of up to three months for alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and easy to transport.

A sample measuring 1.5 inches, consisting of around 200 hair strands (comparable to a #2 pencil size) near the scalp yields 100mg of hair, which is optimal for screening and confirmation. For EtG, additional tests, or when exceeding 10 panels, 150mg of the sample is advised. Using a jeweler's scale for weighing the sample is suggested. If scalp hair is unavailable, an equivalent quantity of body hair can be collected. References to head hair specifically pertain to scalp hair, while body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

There are four primary steps in laboratory processing for drug test results: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial sample processing within the laboratory's system. It involves confirming that the sample was correctly sealed and sent, assigning it a random LAN (Laboratory Accessioning Number), and completing any further data entry needed beyond what an electronic chain of custody might provide.

Screening is a preliminary examination for drugs of abuse. Though cost-effective for ruling out drug usage in most samples, a positive screen requires confirmation to be court-admissible. Any samples testing presumptively positive in Screening need a follow-up confirmation.

For samples identified as presumptively positive during Screening, additional hair is extracted from the original sample for the Extraction phase. This entails extraction of drugs from hair at significantly lower concentrations than other methods such as urine or oral fluid, which makes hair drug screening a challenging methodology.

Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo washing before confirmation as needed. The complete process in the laboratory, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, surpassing the shorter detection period of urine tests.
• Challenging to cheat: Cheating a hair drug test is particularly difficult, ensuring more reliable results.
• Represents usage history: It can reveal a pattern of drug use over time, not merely recent usage.

Limitations:

• Lack of detection for recent use: It takes about 5-7 days for drugs to be detectable in hair.
• Higher expense: Hair drug tests tend to be more costly than other methods of drug testing.
• Result variations: Hair color and individual differences in hair growth can influence the concentration of drug metabolites in hair.

Note: The test, often called a "hair follicle test," actually analyzes the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle tests are often favored over urine tests due to their superior accuracy in capturing a comprehensive substance use history. In James City, NC, this method provides a clearer and more reliable detection of past drug use, helping employers make informed decisions.

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.
