Hair Follicle Drug Testing - Cherry Spring, TX

What it is, How it works

Hair analysis has earned its reputation as a robust method for identifying drug and alcohol consumption. Hair captures long-term information about alcohol and other drug usage by encapsulating biomarkers within the strands as they grow. Samples taken near the scalp can offer close to a 3-month window of detection for both alcohol and drugs. The collection process is straightforward, and the samples are relatively tamper-resistant and easy to transport.

A 1.5-inch segment amounting to about 200 hair strands (approximately the girth of a #2 pencil) from near the scalp provides 100mg of hair, which is perfect for testing and verification. For EtG, additional testing, or tests beyond 10 panels, 150mg of the sample is preferable. It's recommended to measure the sample with a jeweler’s scale. If scalp hair is not available, a comparable amount of body hair can be used. Note that when we talk about head hair, we specifically mean scalp hair. Body hair encompasses all other types, like facial and axillary hair.

Process Overview

There are four primary steps in lab processing for a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial handling of a sample in a laboratory's infrastructure. This phase ensures the sample’s sealed transport, assigns a random Laboratory Accessioning Number (LAN), and completes any extra data entry that an electronic chain of custody system doesn’t cover.

Screening offers a preliminary rapid check for drug abuse indicators. While Screening is an economical approach to exclude drug use in most samples, a positive outcome requires Confirmation to be legally valid. Samples that are provisionally positive in Screening need a follow-up confirmation test.

When a sample is potentially positive at the Screening phase, additional hair is extracted from the original specimen for the Extraction stage. Drugs are extracted from hair in much lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug testing one of the most complex methodologies.

GC/MS, GC/MS/MS, or LC/MS/MS is used for Confirmation of any positive screening findings. All potentially positive samples undergo thorough washing before Confirmation as necessary. The comprehensive laboratory procedure, from Accessioning through Confirmation, is examined under the CAP (College of American Pathologists) Hair criteria and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug consumption for up to 90 days, in contrast to the shorter detection windows of urine tests.
• Hard to manipulate: Manipulating hair drug tests is extremely difficult, thus the results tend to be highly precise.
• Tracks historical usage: These tests can reflect a pattern of drug usage over time, rather than indicating only recent use.

Limitations:

• Cannot detect recent consumption: It typically takes 5-7 days before drugs are traceable in hair.
• Expense: Hair drug tests generally cost more than other drug testing techniques.
• Outcome variability: Factors like hair color and individual hair growth variation can impact the levels of drug metabolites in hair.

Note: Although often called "hair follicle tests," the test examines the hair shaft rather than the follicle under the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle testing to traditional urine tests in Cherry Spring, TX, significant advantages emerge. Hair tests offer a broader detection window, better revealing past substance use.

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.
