Hair Follicle Drug Testing - Linden, IA

What it is, How it works

Hair evaluations have emerged as an effective method for identifying substance and alcohol consumption. Hair provides a comprehensive history of alcohol and other substances by embedding biomarkers within the strands of hair as they grow. When obtained near the scalp, hair offers a detection span of up to about three months for alcohol and other drugs. Hair collection is straightforward, relatively resistant to tampering, and conveniently shippable.

A 1.5-inch segment consisting of around 200 hairs (roughly the thickness of a #2 pencil) from the scalp yields 100mg, the prime quantity for assessment and confirmation. For EtG, additional tests, and/or analysis exceeding 10 panels, a sample of 150mg is advised. Using a jeweler’s scale for precise measurement of the specimen is recommended. In scenarios where scalp hair is unavailable, a comparable volume of body hair can be gathered. When discussing head hair, we are specifically indicating scalp hair alone. Body hair encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

The process for analyzing drug test outcomes in a lab includes Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a specimen into a lab’s system. This process involves verifying that the specimen was appropriately sealed and transported, generating an arbitrary LAN (Laboratory Accessioning Number), and finalizing any supplementary data input absent in an electronic chain of custody system.

Screening consists of a preliminary quick assessment for substance abuse. While Screening is a budget-friendly approach to eliminate drug usage in most specimens, a positive outcome in Screening requires validation to be permissible in a legal setting. Any specimens that register a presumptive positive in Screening necessitate a follow-up confirmation.

Should a specimen indicate a presumptive positive in the Screening stage, additional hair is extracted from the initial sample and prepared for Extraction. In this phase, substances are extracted from hair at a notably lower concentration compared to alternative methodologies (e.g., urine or oral fluid), underscoring why hair drug screening is the most challenging to execute.

Verification of any positive Screening result is undertaken via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed prior to confirmation if required. The comprehensive lab procedure from Accessioning to Confirmation is subjected to review under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can identify drug use for a maximum of 90 days, unlike urine tests that offer a lesser detection span.
• Difficulty in manipulation: It's notably challenging to manipulate a hair drug test, ensuring more dependable results.
• Reveals historical data: It can show a timeline of drug usage, not merely recent consumption.

Limitations:

• Incapable of detecting recent consumption: It requires about 5-7 days for substances to manifest in hair.
• Expense: Hair drug evaluations are typically pricier than alternative drug testing approaches.
• Result variability: Elements like hair color and individual differences in hair growth might influence the concentration of drug metabolites in hair.

Note: Commonly labeled as "hair follicle tests", the procedure actually examines the hair strand and 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.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis.
