This collaboration defines the path for the optimal advancement of the trial. 

In this article, we focus on laboratory sample journey and management – how the material is collected, placed in the appropriate packaging, delivered to the right location, and within the set time frames. We will begin by explaining the basics and fundamentals of the process, outlining the each laboratory sample journey undergoes to add value to every clinical trial.

The process of laboratory sample journey in clinical trials

Before delving into the laboratory sample journey , it is important to understand how the trial setup process works, which documents are essential, and the roles of the Sponsor, CRO, and Central Lab. The setup phase is a critical stage of the study. When done properly, it ensures the laboratory samples are correctly prepared, handled, and their journey is safer and more efficient.

Setup of the trial at Central Laboratory 

The first and most important document at the start of the study setup is the Study Protocol. It is a comprehensive document, prepared by the Sponsor or CRO, that outlines the objectives, design, methodology, statistical considerations, and organization of a clinical trial. When the study begins, the Study Protocol is provided to the Central Lab, which conducts a thorough review to understand the laboratory requirements specified for the trial. This includes identifying the required tests and their specific parameters. The laboratory sample journey has not started yet.

Based on the Protocol and the signed budget agreement, an Analytical Plan is developed. This document serves as the foundation for all laboratory-related activities within the study. It is customized to the study’s specific requirements and includes detailed information such as: 

• The list of required tests and their timelines. 
• The number and structure of visits. 
• The design and composition of sample collection sets 
• The data structure and database configuration for result tracking and reporting. 

The Analytical Plan ensures that all laboratory processes are aligned with the Protocol and that sample collection kits are assembled appropriately.

How is the design of each sample collection established? 

The design of each collection set is established based on the Analytical Plan (AP), which is approved by the Sponsor. This process takes into account the specific tests required for the study, allowing the selection of appropriate tubes and materials for sample collection. Key factors considered include the type of biological material to be collected, packaging materials, transport temperature, and transportation conditions, ensuring all requirements are known and addressed during the design phase. 

The following process is based on the experience and services currently provided by Medicover Integrated Clinical Services. These practices have been tested and approved by our global partners, ensuring reliability and compliance with the highest industry standards. 

The Assembly Team produces custom collection kits tailored to the specific needs of each clinical trial. These kits are designed to minimize pre-analytical errors and maintain sample integrity throughout transportation. Key features of the collection setup include:

• Customized Sample Collection Tubes – we design tubes with specific additives or coatings tailored to the stability and requirements of the analyte, such as PK markers or ADA detection. 
• Anticoagulants – for blood collection, we provide the appropriate anticoagulants to prevent clotting and maintain sample integrity. 
• Preservation Solutions – Some biomarkers may require preservation solutions to ensure sample stability during transportation. 
• Unique Sample Preparation Instructions – Specialized instructions are included to guide sample preparation for advanced testing methods, ensuring optimal results. 
• Temperature-Controlled Components – Kits for temperature-sensitive biomarkers or PK samples may include temperature-controlled compartments or cool packs for sample storage and transport. There is also an availability for ambient, refrigerated, or frozen shipping, using dry ice solutions or validated thermo boxes. You can learn more here about shipping lab samples with dry ice. 

The benefits of dry ice for shipping lab samples 

Different types of kits established at this stage will be prepared to be study-specific, site-specific, and visit-specific, greatly assisting site personnel in easily selecting the appropriate collection set for each patient visit. 

Did you know that Study Setup involves more than just preparing the lab manual and assembling the collection sets? It also includes designing a database to capture all required data as agreed with the Sponsor. The database is structured to facilitate the accurate, efficient, and Protocol-compliant reporting of results to investigators and clients. 

The kit (collection set) must meet all necessary specifications to maintain the stability of the samples from the point of collection to the time of analysis. This ensures sample integrity and reliable test results. 

How is a study-specific Lab Manual prepared? 

Following the completion of the Analytical Plan, a Lab Manual is developed to include detailed instructions on sample collection, handling, packaging, and shipment. The manual is designed specifically for the study and contains information solely related to the samples required for that particular trial. Its content is prepared based on the recommendations provided by the laboratory assigned to analyze the samples.
