Excessive use of antibiotics is a significant public health concern with several severe implications for the development of Antibiotic Resistance and its impact on Gut Microbiota. C-reactive Protein (CRP) is non-specific, acute-phase reactant whose levels increase in response to infection or inflammation due bacterial and viral etiologies. Many studies have explored the role of CRP as a point-of-care tool to assist in decision-making and improve the efficiency of antibiotic prescribing practices among healthcare professionals in primary care settings. The main benefit of POC CRP testing is its ease of use, providing results within 2 to 3 minutes from a simple finger prick, which is optimal for an outpatient clinic. While several studies demonstrate reductions in antibiotic use with POC CRP testing, there are many controversies around those need to be resolved, including the cutoff values of CRP for antibiotic prescription, whether CRP can differentiate bacterial and viral etiologies, and whether a single CRP level can reflect the disease state. Future research needs to focus on developing uniform guidelines for interpreting CRP levels and evaluating whether serial CRP measurements, physician training, especially in primary care and rural settings, to reduce overprescribing. Ultimately, while POC CRP testing can support antibiotic stewardship, its utility must be carefully balanced with sound clinical judgment.
