Could taking macrobid for uti for three days prior to an std test somehow effect the std test result and make it negative even if it should be pos?

Unlikely: Not sure what specific test to which you are referring, but Macrodantin (nitrofurantoin) is very unlikely to alter the results of testing for most stds.
