Microbial contamination risks and clinical safety in platelet-rich plasma therapy and evaluation of rapid microbial detection methods

The risks of microbial contamination were identified during both venipuncture and PRP production. To reduce these risks, it may be necessary to improve disinfection protocols for venipuncture sites and blood collection methods, implementing appropriate facility-specific measures. Although requiring further detection sensitivity improvements, FCM is a promising method for detecting viable bacteria in PRP. Given that microbial contamination cannot be completely eliminated, clinicians providing PRP therapy should remain alert to the potential for postoperative infections and ensure appropriate follow-up protocols are established.
