Hair Follicle Drug Testing - New Haven, IA

What it is, How it works

Hair testing has emerged as an effective tool for identifying drug and alcohol usage. Hair retains a long-term record of alcohol and drug consumption by encapsulating biomarkers within the strands as they grow. When sampled near the scalp, hair can offer a detection window of up to nearly 3 months for drugs and alcohol. Hair is straightforward to collect, somewhat resistant to tampering, and simple to transport.

A 1.5-inch section of about 200 hair strands (approximately the thickness of a #2 pencil) near the scalp yields 100mg of hair, the preferred sample amount for screening and confirmation. In cases of EtG, add-ons, or tests exceeding 10 panels, a 150mg sample is advised. We suggest measuring the sample on a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair may be utilized. References to head hair specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning involves integrating the sample into the lab’s system, verifying that it was securely sealed and correctly shipped, assigning it a LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody.

Screening serves as an initial, economical assessment for drugs of abuse. While efficient for eliminating drug use suspicions on most samples, a positive screen must be confirmed for legal admissibility. Samples that show presumptive positive results in Screening necessitate further confirmation.

If a sample appears positive in the Screening phase, additional hair is used from the initial sample and prepared for Extraction. This phase extracts drugs from hair in notably lower concentrations compared to methods like urine or oral fluid, highlighting the complexity of hair drug screening.

Confirmation of any positive screenings is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if needed. The complete lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair standard and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can reveal drug use for up to 90 days, unlike urine tests with a shorter window.
• Challenges in falsification: Hair drug tests are difficult to falsify, ensuring more precise results.
• Offers historical insight: It reveals patterns of drug use over time, beyond recent use.

Limitations:

• Recent use indetectability: Drugs take roughly 5-7 days to appear detectable in hair.
• Expense: Hair drug tests generally cost more than other drug testing techniques.
• Outcome variability: Hair color and personal growth variations can influence drug metabolite concentration in hair.

Note: Despite being termed "hair follicle tests", the analysis actually 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.
