Hair Follicle Drug Testing - Stidham, OK

What it is, How it works

Viewing hair testing as a significant method in detecting alcohol and drug usage is now prevalent. Hair captures a historical record of alcohol and drug consumption by locking biomarkers within the structure of the growing hair shaft. Sampling hair near the scalp can provide a detection timeframe for alcohol and drugs of up to roughly three months. The collection process is straightforward, it is relatively resistant to tampering, and it is convenient for shipping.

A sample size of 1.5 inches, comprising roughly 200 hair strands (similar in thickness to a #2 pencil) cut close to the scalp yields 100mg, which is the preferred quantity for initial testing and verification. For EtG, supplementary items, and/or testing exceeding 10 panels, a 150mg sample is advised. Utilizing a jeweler’s scale is recommended for precision in specimen measurement. If scalp hair cannot be obtained, a similar quantity of body hair is an acceptable substitute. The term "head hair" strictly pertains to scalp hair, while "body hair" encompasses all other types, including facial and axillary hair.

Process Overview

The laboratory processing chain for drug test results encompasses four principal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is concerned with the initial integration of the sample within the laboratory infrastructure. This step ensures the sample was adequately sealed and dispatched, allocates a unique LAN (Laboratory Accessioning Number), and finalizes any supplemental data entry absent in an electronic chain of custody framework.

Screening consists of a preliminary evaluation for commonly abused substances. Although Screening offers an economical method to disprove drug consumption in the majority of samples, a confirmed positive screen is necessary for legal validation. Samples that yield presumptive positive results in the Screening phase necessitate an additional validation step.

Upon identifying a presumptive positive result during Screening, more hair is extracted from the original sample and readied for the Extraction stage. During Extraction, substances are isolated from the hair at a considerably lower concentration level compared to other techniques (e.g., urine or saliva), which contributes to the complexity of hair drug testing.

Verification of any positive results from Screening is achieved using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Pre-validation processes include washing all samples testing presumptive positive. Both the entire laboratory procedure from Accessioning to Confirmation adheres to scrutiny under the CAP (College of American Pathologists) Hair accreditation along with ISO/IEC 17025 compliance.

Advantages of hair drug testing:

• Long detection window: Hair drug analysis can identify drug use up to 90 days, whereas urine tests offer a briefer detection period.
• Difficulty to cheat: Hair drug testing presents substantial challenges for manipulation, thereby enhancing result accuracy.
• Provides historical data: It reveals a comprehensive pattern of drug use over time, surpassing immediate consumption detection.

Limitations:

• Cannot detect recent use: Drugs require approximately 5-7 days before they become traceable in hair samples.
• Cost: Typically, hair drug testing incurs higher expenses relative to other drug testing techniques.
• Variations in results: Variables such as hair color and individual hair growth patterns can influence drug metabolite levels in hair.

Note: While frequently termed as "hair follicle tests," the actual analysis focuses on the hair strand itself, 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.
