Hair Follicle Drug Testing - Sonterra, TX

What it is, How it works

The utilization of hair testing has been recognized as an effective method for identifying the presence of drugs and alcohol consumption. Hair retains a prolonged record of substance use by encapsulating biomarkers within the fibrous structure of the hair as it grows. When clipped close to the scalp, hair can reveal a detection range of up to roughly three months for alcohol and drugs. Collecting hair is straightforward, not easily tampered with, and conveniently shipped.

A 1.5-inch segment consisting of approximately 200 hair strands (approximately equivalent to a #2 pencil's width) near the scalp yields 100mg of hair, which is an optimal sample size for initial screening and verification. For EtG assessments, additional analyses, and/or tests exceeding 10 panels, 150mg of the sample is advisable. It's suggested to measure the specimen using a jeweler’s scale. If scalp hair isn't accessible, an equivalent quantity of body hair can be utilized. Reference to head hair specifically implies scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The processing of a drug test result in a lab involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary integration of a specimen into a lab's system. This step involves ensuring the sample was correctly sealed and dispatched, assigning a randomized LAN (Laboratory Accessioning Number), and completing any supplemental data entry not included by an electronic chain of custody framework.

Screening includes an initial rapid assessment for prohibited substances. While it is an economical method to exclude drug presence in most tests, confirming a positive result is necessary for legal validation. Samples that are initially positive require a secondary confirmation test.

For samples initially testing positive during Screening, additional hair is retrieved from the original sample for the Extraction process. Drugs are extracted from hair at significantly lower concentrations than with other techniques (e.g., urine or saliva), making hair drug screening remarkably complex.

Confirmation of any positive screening results is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Prior to such confirmation, all tentative positive samples undergo a cleansing process as required. The full processing from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can ascertain drug usage up to 90 days, unlike urine tests with a shorter detection period.
• Cheating is difficult: Tampering with hair drug tests is highly challenging, ensuring more reliable results.
• Provides usage patterns: It reflects a timeline of substance usage, not just recent consumption.

Limitations:

• Does not indicate recent use: Detection of drugs in hair requires about 5-7 days.
• Expense: Generally, hair drug tests incur higher costs compared to other testing methods.
• Result variability: Differences in hair color and growth rates among individuals can influence the levels of drug metabolites detected in hair.

Note: Although often noted as "hair follicle tests", the analysis focuses on the hair shaft and not the follicle itself beneath the scalp.

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.
