Hair Follicle Drug Testing - Arcola, TX

What it is, How it works

Hair analysis is increasingly recognized as a robust method for identifying drug and alcohol consumption. Hair records a prolonged timeline of substance use by embedding biomarkers within the fibers of the hair strand as it grows. When sourced near the scalp, hair can offer a detection period of up to roughly 3 months for alcohol and other substances. Collecting hair is straightforward, relatively resistant to tampering, and convenient to transport.

A sample of 1.5 inches comprising approximately 200 hair strands (similar to the size of a #2 pencil) nearest to the scalp yields about 100mg of hair, which is the optimal amount for evaluation and verification. For EtG, auxiliary tests, and/or screenings exceeding 10 panels, 150mg of the sample is advised. We suggest the specimen be weighed on a jeweler’s scale. In the absence of scalp hair, a comparable quantity of body hair may be utilized. When mentioning head hair, it denotes scalp hair exclusively. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The primary stages in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step where a sample is integrated into a laboratory’s system. This process ensures the sample was correctly sealed and sent, a random LAN (Laboratory Accessioning Number) is designated, and additional data entry omitted by an electronic chain of custody system is completed.

Screening is a preliminary swift check for drug abuse. While it effectively eliminates drug use in most samples, a positive screen must be verified for court admission. Presumptively positive samples from Screening require secondary confirmation.

Should a sample be presumptively positive during Screening, more hair is extracted from the original sample and prepared for Extraction. In this step, hair releases drugs at a substantially lower concentration than other methods (e.g., urine or oral fluid), making hair drug analysis the most challenging method to execute.

For any positive screening result, Confirmation is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before needed confirmation. The entire laboratory process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can trace drug usage for up to 90 days, whereas urine tests have a briefer detection period.
• Resistance to alteration: Manipulating a hair drug test is quite challenging, leading to more precise outcomes.
• Reveals historical usage: It shows a trend of drug consumption over time, not just immediate use.

Limitations:

• Lacks recent detection: It typically takes 5-7 days for substances to be traceable in hair.
• Cost: Hair drug analyses generally incur higher expenses compared to other testing techniques.
• Variability in results: Elements like hair color and personal hair growth differences can influence the concentration of drug residues in the hair.

Note: Despite the common term "hair follicle tests", the analysis examines the hair strand instead of the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
