Various aspects of the invention provide systems and methods for improving the privacy-protection of the exchange of STD's test results and the utility of STD test results. One aspect of the invention provides a computer-implemented method of improving privacy-protection during the exchange of STD test results by preventing the exchange of STD test results if user-definable criteria are not met and deliberately obscuring the cause of prevented attempts at exchanging STD test results. The method includes providing a software application for importing STD test results; inputting criteria; attempting to exchange STD test results; and either preventing or allowing the exchange of STD test results at a plurality of stages. Another aspect of the invention provides a computer-implemented method of improving the utility of STD test results by recommending safe sexual contact practices and sexual health-related products and services based upon the use of algorithms.
