Hair Follicle Drug Testing - Bay City, MI

What it is, How it works

Hair analysis is now widely recognized as a potent method for identifying drug and alcohol consumption. Hair strands can capture biomarkers within their growth, offering a prolonged history of alcohol and drug usage. When sourced near the scalp, hair can offer an approximately 3-month timeframe for detecting alcohol and drugs. Hair collection is straightforward, tough to falsify, and convenient for transport.

A sample size of 1.5 inches, roughly consisting of 200 hair strands (comparable to the diameter of a #2 pencil), close to the scalp supplies 100mg of hair, perfect for testing and confirmation. For EtG, additional analyses, and/or evaluations exceeding 10 panels, a specimen weighing 150mg is advisable. It's recommended to weigh the specimen using a jeweler’s scale. Should scalp hair be unavailable, a comparable volume of body hair may be used. Head hair specifically refers to scalp hair. Body hair encompasses all alternative hair types (such as facial, axillary, etc.).

Process Overview

The laboratory processing of drug test results encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to initially processing a sample into the lab's system. This step includes verifying the proper sealing and shipping of the sample, assigning an arbitrary LAN (Laboratory Accessioning Number), and finalizing any additional data entry absent in an electronic chain of custody system.

Screening represents an initial swift assessment for substance abuse. While Screening is an economical method to discard most samples for drug use, a positive outcome must be validated for legal admissibility. All samples with a presumed positive result from Screening necessitate additional confirmation.

When a sample shows a presumed positive result in the Screening phase, more hair is derived from the original specimen for the Extraction step. In this phase, drug substances are retrieved from hair at notably lower concentrations compared to other processes (such as urine or oral fluid testing), which is why hair drug screening is considered a challenging methodology.

Confirmation of any positive screening results occurs via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with a presumed positive are cleansed pre-confirmation if necessary. The entire laboratory procedure from Accessioning to Confirmation is reviewed following both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can trace drug use for a period reaching up to 90 days, in contrast with urine tests which have a more limited detection period.
• Resistance to tampering: It's exceedingly tough to manipulate a hair drug test, thus enhancing the accuracy of results.
• Insightful historical data: It demonstrates a sequence of drug usage over time, rather than just recent instances.

Limitations:

• Incapable of detecting recent usage: It requires about 5-7 days for substances to be noticeable in hair.
• Expense: Compared to other drug testing techniques, hair drug tests typically incur higher costs.
• Result fluctuations: Elements like hair color and individual differences in hair growth can sway the levels of drug metabolites in hair.

Note: Although often named "hair follicle tests", the analysis focuses on the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Superior Detection Accuracy: Hair follicle tests surpass urine tests in catching long-term substance use, providing detailed and accurate results not achievable with traditional methods.

Reliable Over Time: Unlike urine tests, hair analysis unveils drug histories over extended periods, ensuring thorough and accurate assessments.

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.
