Hair Follicle Drug Testing - Crystal, NV

What it is, How it works

Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. Hair retains a prolonged record of substance use by capturing biomarkers in its developing fibers. When taken near the scalp, hair can reveal a detection period of up to around three months for substances. Hair is straightforward to gather, relatively hard to tamper with, and easy to transport.

A hair sample of 1.5 inches, containing approximately 200 strands (about the thickness of a #2 pencil) nearest the scalp, yields 100mg of hair, the optimal amount for both initial and confirmatory tests. For EtG, additional tests, and/or panels exceeding ten drugs, 150mg of the sample is advised. It's recommended to weigh the sample using a jeweler’s scale. If scalp hair isn't accessible, an equivalent quantity of body hair might be collected. "Head hair" specifically refers to scalp hair only, while "body hair" covers all other types (facial, armpit, etc.).

Process Overview

The laboratory analysis of drug test results encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially processed into the lab system. This step involves confirming the sample was properly sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not captured by an electronic chain of custody system.

Screening offers a preliminary check for drug presence. Though Screening is an economical means to dismiss drug use in most samples, a positive screen demand confirmation to stand in court. Any samples testing positive in Screening necessitate a further verification process.

If a sample shows a tentative positive in Screening, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are isolated from hair at much lower concentrations than other methods (e.g., urine or saliva), making hair drug testing the most challenging method to execute.

Positive screening findings proceed to Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All positive samples are cleansed before confirmation if required. The complete laboratory procedure from Accessioning to Confirmation undergoes review complying with CAP (College of American Pathologists) Hair specifications and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair tests can identify drug usage for up to 90 days, surpassing urine tests with shorter detection spans.
• Hard to falsify: It's exceptionally challenging to deceive a hair drug test, ensuring more accurate results.
• Historical usage data: It can illustrate drug usage events over time, not merely recent usage.

Limitations:

• Inability to detect recent usage: It takes around 5-7 days for drugs to surface detectably in hair.
• Expense: Hair drug tests generally incur higher costs than other testing methods.
• Result variations: Elements like hair color and personal hair growth differences can influence drug metabolite levels in hair.

Note: Although referred to as "hair follicle tests", the test principally examines 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.
