Hair Follicle Drug Testing - Felton, AR

What it is, How it works

Hair testing is regarded as an effective method for detecting drug and alcohol use. Hair encases a long-term record of alcohol and drugs by embedding biomarkers within the strands as they grow. When hair is collected close to the scalp, it offers an approximate 3-month detection window for drugs and alcohol. The collection of hair is straightforward, somewhat resistant to tampering, and easy to send.

A 1.5-inch segment of roughly 200 hair strands (approximately equivalent to a #2 pencil) nearest the scalp yields 100mg of hair, which is the optimal sample for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg is suggested. Utilizing a jeweler’s scale for specimen measurement is advisable. If scalp hair is not available, an equivalent amount of body hair might be used. 'Head hair' specifically refers to scalp hair, while 'body hair' encompasses all other types (such as facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test entails four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses processing a sample into a lab's system. This step checks if the sample was sealed and transported correctly, attributes a random LAN (Laboratory Accessioning Number), and includes any additional data entry absent in an electronic chain of custody system.

Screening comprises an initial check for the presence of drugs. Although a cost-efficient means to exclude drug use in most samples, a positive screen necessitates confirmation before it can be court-admissible. Presumptive positive samples from Screening need secondary confirmation.

For samples deemed presumptively positive at the Screening stage, additional hair is drawn from the initial sample for Extraction. Drugs are isolated from hair at significantly lower concentrations than in other methods like urine or oral fluid tests, rendering hair drug screens the most challenging methodology.

Positive screening results are validated via GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptively positive samples are cleansed before confirmation as needed. The entire process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair certification and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests reveal drug use for up to 90 days, unlike urine tests which cover a shorter period.
• Hard to cheat: Cheating on a hair drug test is extremely challenging, enhancing accuracy.
• Tracks usage history: It exposes a pattern of drug use over time, not merely recent consumption.

Limitations:

• Cannot catch recent consumption: Drugs take about 5-7 days to show up in hair.
• Expense: Hair drug tests often incur higher costs than other drug test methods.
• Result variability: Hair color and personal variations in growth can impact drug metabolite levels in hair.

Note: Commonly labeled as "hair follicle tests", the examination actually analyzes the hair strand and not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

Why does hair follicle testing outshine urine tests in Felton, AR? Detection accuracy and reliability are the main reasons. While urine tests offer a shorter detection window, hair tests provide a comprehensive view of drug use history.

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.
