GB/T 43279.1-2023

This standard specifies the requirements for the handling, transport, storage, and processing of venous whole blood specimens prior to the isolation of cellular RNA for molecular in vitro diagnostic testing. It is applied in clinical laboratories and diagnostic settings to ensure the integrity and quality of RNA extracted from blood cells, which is critical for accurate gene expression analysis and molecular pathology. The standard is particularly relevant for tests involving reverse transcription PCR (RT-PCR) or RNA sequencing used in disease diagnosis, monitoring, and research.
