Hair Follicle Drug Testing - Oshkosh, NE

What it is, How it works

Hair testing is recognized as a strong method for identifying drug and alcohol consumption. Hair offers an extended history of substance intake by capturing biomarkers within the fibers of the developing hair strand. When gathered near the scalp, hair can suggest up to a 3-month timeframe for alcohol and drug detection. Hair is straightforward to gather, relatively resistant to tampering, and simple to transport.

A 1.5-inch segment of approximately 200 hair strands (roughly the size of a #2 pencil) closest to the scalp provides 100mg of hair, which is the preferred amount for analysis and confirmation. For EtG, extra panels, and/or tests beyond 10 panels, 150mg of the sample is advised. We suggest utilizing a jeweler’s scale to measure the sample. If scalp hair is not present, a comparable quantity of body hair might be used. When mentioning head hair, we specifically mean scalp hair only. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step where a sample enters the laboratory system. It involves ensuring the sample is securely sealed and shipped correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any required data entry absent in an electronic chain of custody system.

Screening is a preliminary assessment to detect substance abuse. Although Screening is an economical method to dismiss drug use in most samples, a positive result requires confirmation to be considered valid in court. All presumptive positive samples in Screening mandate additional confirmation.

If Screening suggests a positive result, additional hair is taken from the original sample for Extraction. In this phase, drugs are extracted from hair at a much lower concentration than other techniques (e.g., urine or oral fluid), making hair drug analysis the most challenging technique to execute.

GC/MS, GC/MS/MS, or LC/MS/MS carries out the Confirmation of any positive Screen. Before confirmation, all presumptive positive samples are washed if needed. The full lab process, from Accessioning to Confirmation, is conducted following both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection period: Hair drug screenings can identify drug involvement for as long as 90 days, unlike urine tests which cover a shorter period.
• Hard to manipulate: It's almost impossible to deceive a hair drug test, which ensures more reliable outcomes.
• Offers usage pattern data: It can display a sequence of substance use over time, not just recent consumption.

Limitations:

• Inability to detect recent use: It takes about 5-7 days for metabolites to be present in hair.
• Expense: Hair drug examinations are typically pricier than other testing methods.
• Result variations: Elements like hair color and individual hair growth rates can influence the metabolite levels in hair.

Note: Though commonly called "hair follicle tests," the examination focuses on the hair strand itself, excluding the follicle beneath the skin.

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.
