1. Introduction
Biospecimen and samples quality assurance is a crucial aspect of modern research as the integrity of biological samples directly affects the validity and reproducibility of scientific findings. From basic research to clinical trials, biospecimen quality plays a pivotal role in unraveling the complexities of diseases and developing effective therapies. However, many clinical studies have underutilized their biobanked samples due to unmet quality standards, resulting in wasted resources and missed opportunities for advancing research.
These issues can be mitigated by implementing proper handling and processing methods to ensure pristine samples for downstream analysis. Participant samples and data are precious and should be handled responsibly for scientific, research, and therapeutic purposes. Randomly selecting samples for quality testing throughout the study lifecycle provides ongoing assurance that all standards are being met while balancing the need for rigorous quality control with the realities of cost and time constraints.
Depending on the sample type and downstream analysis, specific processing steps, intermediate testing, and sample metadata tracking can benefit biospecimen quality assurance. For instance, in blood samples, timely centrifugation and separation of plasma preserve sample integrity, while tissue samples may require immediate freezing to prevent degradation. Intermediate testing, such as assessing sample purity or concentration, ensures the sample's suitability for further analysis.
Maintaining sample integrity throughout the lifecycle of a biospecimen presents numerous challenges, including improper handling, storage conditions, and processing techniques that can introduce variability and compromise sample quality. This can lead to misleading results, wasted resources, and delays in scientific progress. As research complexity increases and the demand for high-quality biospecimens grows, traditional quality assurance methods may fall short.
The application of artificial intelligence (AI) and machine learning (ML) holds immense potential in this area. By leveraging these modern technologies, researchers can address biospecimen quality assurance challenges, streamline processes, and ensure sample integrity. AI and ML algorithms analyze vast data, identify patterns, and make predictions, enabling researchers to optimize sample collection, storage, and processing protocols. From automated quality control checks to predictive modeling of sample degradation, the integration of AI and ML in biospecimen quality assurance has the potential to revolutionize the field and accelerate scientific discoveries.
