Introduction:
Approximately 15 million deaths occur globally each year due to infectious diseases. Timely diagnosis is crucial in promoting cure and preventing disease transmission. Currently, molecular diagnostics have replaced many conventional diagnostic tools due to their inherent limitations. However, the full potential of Immuno Polymerase Chain Reaction (IPCR) remains largely untapped.
Areas Covered:
This review focuses on the use of IPCR in the diagnosis of different bacterial diseases, highlighting its advantages over traditional methods.
Expert Opinion:
Early and accurate diagnosis of infectious diseases is crucial because it enhances treatment effectiveness, reduces morbidity and mortality, helps identify potential causes of sepsis earlier, and reduces the risk of unknowingly spreading the disease to others. IPCR in turn has shown promise for the early diagnosis of bacterial diseases as an alternative to conventional culture-based or serological diagnostic assays leading to delayed diagnosis and treatment. IPCR has the potential to revolutionize the diagnostic field due to its increased sensitivity and specificity. Although efforts are needed to reduce the time of the assay and to reduce background noise, IPCR can be combined with other platforms like lateral flow assay/biosensors/automation to improve its use as a point-of-care assay, especially in resource-limited settings.
