Hair Follicle Drug Testing - Oak Ridge, TX

What it is, How it works

Hair analysis is now recognized as a crucial method for identifying drug and alcohol consumption. The strands capture biomarkers within the hair’s growing fibers, offering an extended history of substance use. When sampled near the scalp, this method can unveil drug and alcohol use for up to three months. Collecting hair is straightforward, hard to tamper with, and convenient to send.

A sample size of 1.5 inches, or approximately 200 hairs (roughly a #2 pencil’s width), yields 100mg, ideal for testing and verification. For EtG, additional panels, or tests over 10 panels, a recommended 150mg is necessary. We suggest using a jeweler’s scale for precise measurement. If head hair isn’t available, an equivalent amount of body hair is acceptable. Head hair implies scalp hair only, whereas body hair covers all other hair types (e.g., facial, axillary).

Process Overview

Processing a drug test result in the lab involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first step, where a sample enters the lab’s system. This step includes verifying the integrity and proper shipment of the sample, generating a random LAN (Laboratory Accessioning Number), and finalizing data entry absent in any digital chain of custody.

Screening provides an initial brief assessment for substance abuse. While Screening efficiently eliminates drug presence in most cases, positive findings require confirmation for legal validity. Any sample appearing positive during Screening mandates additional confirmation.

Should the Screening stage yield a presumptive positive, extra hair is extracted from the initial sample for the Extraction phase. In this phase, drugs are derived from hair at notably lower concentrations compared to other methods (like urine or saliva), making hair screening particularly challenging.

Any initial positive result is confirmed via GC/MS, GC/MS/MS, or LC/MS/MS technology. Presumptive positive samples undergo washing before confirmation, if needed. Each lab phase, from Accessioning through Confirmation, is scrutinized under CAP (College of American Pathologists) standards and aligned with ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair testing can reveal drug use up to 90 days, unlike urine tests with shorter detection spans.
• Slim chance of manipulation: The accuracy is enhanced as it’s tough to deceive a hair test.
• Chronological insight: It delivers usage patterns over time, not just recent consumption.

Limitations:

• Incapable of identifying recent use: Detection in hair takes about 5-7 days post-consumption.
• Higher cost: These tests typically cost more than other testing methods.
• Result variations: Hair color and personal hair growth can influence metabolite concentrations.

Note: Though often called "hair follicle tests", the analysis zeroes in on the hair strand, not the follicle 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. 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.

Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols.
