Hair Follicle Drug Testing - Nogal, NM

What it is, How it works

Hair testing has become an effective method for identifying drug and alcohol usage. Hair records a prolonged timeline of substance intake by embedding biomarkers within the fibers of the developing hair strand. When obtained near the scalp, hair can offer nearly a 3-month timeframe for detecting alcohol and other substances. Hair is straightforward to collect, relatively hard to tamper with, and convenient to transport.

A 1.5-inch portion consisting of about 200 hairs (comparable to the girth of a #2 pencil) near the scalp yields 100mg of hair, the perfect quantity for both screening and verification. For EtG, supplementary tests, and/or analyses exceeding 10 panels, 150mg of the sample is advised. It's advisable to weigh the sample on a jeweler’s scale. If head hair is inaccessible, an equivalent portion of body hair might be gathered. References to head hair denote only scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

The four chief stages in the lab handling of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary assimilation of a sample into a lab’s framework. This step includes ensuring the sample was properly sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data input absent from an electronic chain of custody system.

Screening executes an initial rapid assessment for drug misuse. Although screening is an economical way to eliminate drug consumption on most samples, a positive result requires confirmation for legal admissibility. Any samples testing presumptively positive in Screening necessitate secondary verification.

When a sample appears presumptively positive during Screening, additional hair is drawn from the initial sample and readied for Extraction. In this step, drugs are retrieved from hair at a significantly lower concentration compared to other techniques (e.g., urine or oral fluid), which is why hair drug testing is the most complex method to execute.

Verification of any positive Screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleansed before confirmation as necessary. The full lab process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection interval.
• Tough to deceive: It is extremely challenging to bypass a hair drug test, thus the results are more trustworthy.
• Offers historical insights: It can display a substance usage trend over time, instead of merely recent consumption.

Limitations:

• Inability to identify recent use: It takes around 5-7 days for drugs to become noticeable in hair.
• Expense: Hair drug tests are typically pricier than other drug testing approaches.
• Result variations: Elements like hair color and personal differences in hair growth can influence drug metabolite levels in hair.

Note: Even though often referred to as "hair follicle tests", the analysis pertains to the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Nogal, NM, offers a distinct advantage over traditional urine tests due to its superior detection capabilities.

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.
