diagnosis of swine flu: wieghting between false positive and false negative
Editor, I read the recent publication by Mann et al. with a great interest. Mann et al. concluded that " There is a significant risk of harm with false-positive diagnoses and potential delays in appropriate treatment ." I agree that there are several problem in diagnosis of swine flu. Several problems can lead to the failure of using any scoring system or algorithm for diagnosis [2-3]. On the other hands, although several new diagnostic tools can be availble, the problem of false positive can be seen. How to manage and weight for risk and benefit on using simple method with possible false negative and new modern tools with possible high cost and false positive should be the topic to be discussed.
