Background:

Diagnostic laboratory test errors are frequently caused by preanalytical variability, affecting nearly 70% of results.
Preanalytical factors encompass all tissue processing steps from collection to laboratory testing.
Existing transport protocols are insufficient for live solid tumor tissue specimens.

Purpose of the Study:

To address the critical need for standardized preanalytical protocols for live solid tumor tissue.
To reduce variability in biospecimen integrity.
To enhance diagnostic accuracy for personalized medicine.

Main Methods:

Development of a comprehensive protocol for the collection of solid tumor tissue.
Standardization of handling, packaging, and cold-chain logistics for biospecimens.
Establishment of procedures for the receipt of tissue specimens in the laboratory.

Main Results:

The protocol aims to preserve the viability of live solid tumor tissue specimens.
Implementation of standardized procedures minimizes preanalytical variability.
Consistent handling ensures higher quality biospecimens for analysis.

Conclusions:

Standardized preanalytical protocols are essential for reliable diagnostic testing.
This protocol provides a framework for consistent collection and transport of live solid tumor tissues.
Improved biospecimen integrity supports advancements in personalized medicine and accurate diagnostics.
