Hair Follicle Drug Testing - Joseph City, AZ

What it is, How it works

Hair evaluation is now recognized as an effective means for identifying drug and alcohol consumption. Hair captures a prolonged history of alcohol and drug intake by embedding biomarkers within the fibers of the hair strand as it grows. When cut near the scalp, hair can reveal usage information for alcohol and other drugs for roughly a 3-month timeframe. Hair collection is straightforward, tricky to tamper with, and convenient to transport.

A 1.5-inch portion containing approximately 200 hair strands (around a #2 pencil's diameter) nearest to the scalp provides 100mg of hair, the perfect specimen for analysis and verification. For EtG, supplementary tests, and/or those exceeding 10 panels, it's advisable to gather 150mg of the hair. Using a jeweler’s scale for specimen weighing is suggested. When scalp hair isn't available, an equal amount of body hair can be used. By head hair, we mean just scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory journey of a drug test outcome comprises four essential stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial intake of a specimen into the lab’s system. This step checks that the sample is sealed correctly and delivered as required, assigns a unique LAN (Laboratory Accessioning Number), and completes any unfinished data entry absent in an electronic chain of custody.

Screening involves a preliminary assessment for substances of abuse. Despite Screening being an affordable approach to dismiss drug intake in most samples, a positive result needs further confirmation for legal admissibility. Any samples preliminarily positive during Screening require a follow-up confirmation.

Should a sample indicate a presumptive positive during Screening, additional hair is extracted from the primary sample and readied for Extraction. At this juncture, drugs are recovered from hair at diminished concentrations compared to other techniques (e.g., urine or oral fluid), signifying why hair drug analysis is the most intricate procedure.

Positive results from Screening are validated through GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation as deemed necessary. From Accessioning to Confirmation, the entire lab process is scrutinized under CAP (College of American Pathologists) Hair specification and ISO / IEC 17025 accreditation.

Benefits of hair drug testing:

• Extended detection period: Hair drug evaluations can identify drug intake spanning 90 days, unlike urine tests with shorter detection periods.
• Challenge to manipulate: Manipulating a hair drug test is challenging, enhancing the accuracy of outcomes.
• Chronological information: It uncovers a pattern of substance use over time, not merely recent consumption.

Drawbacks:

• Inability to detect recent intake: A span of 5-7 days is required for drugs to appear in hair.
• Price: Hair drug analyses tend to be costlier than alternative drug testing approaches.
• Inconsistent results: Elements such as hair pigmentation and personal hair growth variation can impact the drug metabolite levels in hair.

Note: Although often labeled as "hair follicle tests", the analysis focuses on the hair strand itself, not the follicle under the scalp

Why Hair Follicle Testing Beats Urine Testing

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.
