Hair Follicle Drug Testing - Otway, NC

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. By encapsulating biomarkers within the strands of hair as it grows, hair offers a comprehensive overview of substance use over an extended period. When collected near the scalp, it offers an approximate three-month detection window for alcohol and various drugs. Hair sampling is straightforward, challenging to manipulate, and convenient for transportation.

A sample measuring 1.5 inches consisting of roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg, the optimal amount for both screening and confirmation. For tests involving EtG, add-ons, and those exceeding 10 panels, 150mg is advised. We suggest using a jeweler’s scale to weigh the sample. If scalp hair cannot be obtained, an equivalent quantity of body hair is acceptable. The term "head hair" specifically refers to scalp hair, while "body hair" encompasses all other forms of hair (facial, axillary, etc.).

Process Overview

The laboratory process for drug test results consists of four pivotal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase, involving the integration of a sample into a laboratory's system. This step ensures that the sample is properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data entry absent in an electronic chain of custody system.

Screening provides a preliminary evaluation for drugs of abuse. While it is a cost-effective method to eliminate drug use for most samples, a positive result during Screening must be validated to be legally acceptable. Samples flagged as presumptively positive in Screening necessitate further confirmation.

For samples flagged as presumptive positive during Screening, additional hair is extracted from the initial sample and readied for Extraction. At this stage, drugs are isolated from hair at notably lower concentrations than other methods (e.g., urine or oral fluid), highlighting why hair drug analysis poses significant challenges.

Confirmation for any positive screening is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleansed prior to confirmation when necessary. The entire lab process, from Accessioning through Confirmation, undergoes evaluation under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, in contrast to urine tests which offer a shorter detection timeframe.
• Resistant to manipulation: Tampering with a hair drug test is extremely challenging, enhancing result accuracy.
• Offers historical patterns: It reveals a drug use trend over time rather than just recent usage.

Limitations:

• Inability to identify recent use: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests are typically costlier than alternative drug testing approaches.
• Result variations: Factors such as hair color and personal differences in hair growth rate can influence drug metabolite levels in the hair.

Note: Although commonly termed "hair follicle tests," the analysis is conducted on the hair strand itself, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Otway, NC, surpasses conventional urine tests in multiple ways. Its superior detection span and accuracy offer a marked advantage.

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.
