Hair Follicle Drug Testing - Radar Base, TX

What it is, How it works

Hair testing is now regarded as an effective approach for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and other substances by encapsulating biomarkers within the strands as they grow. When sampled near the scalp, hair can reveal alcohol and drug usage for up to a 3-month period. The collection of hair is straightforward, with minimal chances of tampering, and it's convenient to send for analysis.

A sample measuring 1.5 inches and consisting of roughly 200 hair strands (about the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal amount for both preliminary tests and confirmatory evaluations. For EtG, additional components, and/or assessments exceeding 10 panels, a 150mg specimen is advised. Using a jeweler’s scale to weigh the sample is suggested. If no scalp hair is present, a similar quantity of body hair may be utilized. References to head hair pertain solely to scalp hair, whereas body hair encompasses all other categories (facial, axillary, etc.).

Process Overview

The laboratory evaluation of a drug test outcome involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial handling of a sample within a laboratory context. It ensures the sample is sealed and transported correctly, assigns a random LAN (Laboratory Accessioning Number), and handles any supplementary data entry absent from an electronic custody documentation system.

Screening encompasses a preliminary assessment for common drug use. While it is an economical method to discount drug intake in most cases, a positive screen must be validated to be legally acceptable. All samples with a presumptively positive Screening result require further confirmation.

Upon a presumptively positive outcome in Screening, an additional portion of hair from the original sample undergoes preparation for Extraction. This phase involves isolating drugs from hair at a lower concentration compared to alternative methods (e.g., urine or oral fluid), making hair drug testing one of the most complex methodologies.

Confirmatory tests for any positive Screening results are administered using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive outcomes are cleaned before confirmation if needed. The entire lab process from Accessioning to Confirmation is monitored via both CAP (College of American Pathologists) Hair designation and accreditation compliant with ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug usage for up to 90 days, contrasting with urine tests which have shorter detection spans.
• Hard to deceive: Cheating on a hair drug test is extremely challenging, increasing result accuracy.
• Chronological data: It offers a historical pattern of drug use rather than immediate consumption.

Limitations:

• Incapable of identifying recent drug use: Drugs become detectable in hair approximately 5-7 days post-usage.
• Expense: Hair drug tests tend to be costlier than alternative testing methods.
• Outcome variability: Factors like hair color and individual hair growth variations can influence drug metabolite concentration in hair.

Note: Commonly labeled as "hair follicle tests," the analysis targets the hair strand itself and not the follicle embedded 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.
