Point of care (POC) molecular diagnostics refers to diagnostic tests conducted close to the patient, providing quick results. According to a report by MarketsandMarkets, the global point of care molecular diagnostics market is projected to grow from USD 2.0 billion in 2023 to USD 3.4 billion by 2028, driven by a CAGR of 10.6%. This growth is fueled by the increasing prevalence of infectious diseases and the need for rapid diagnostic tools in various healthcare settings. The significance of POC diagnostics lies in its ability to provide timely results, enabling healthcare providers to make immediate treatment decisions, which can significantly improve patient outcomes.
1.2. How Point of Care Molecular Diagnostics Work
The fundamental principle behind point of care molecular diagnostics is to detect specific genetic markers indicative of a particular disease or condition. These tests use techniques such as polymerase chain reaction (PCR) or isothermal nucleic acid amplification to amplify the target DNA or RNA sequences. The amplified genetic material is then detected using various methods, such as fluorescence or colorimetric assays, to provide a positive or negative result. Unlike traditional lab-based molecular diagnostics, which require samples to be sent to a central laboratory and can take hours or days to return results, POC molecular diagnostics offer results within minutes. This rapid turnaround time is crucial in time-sensitive situations, such as diagnosing infectious diseases like influenza or COVID-19, where immediate treatment can significantly impact patient outcomes. The portability and ease of use of POC devices also make them ideal for use in remote or resource-limited settings where access to central laboratories may be limited.
