Kell, I am a pro at MSU samples, I have UTI freq throughout preg very annoying. Sometimes the results from MSU can come back saying they weren't collected properly sometimes this is because the jar is contaminated (wasn't sterile to start with) or they didnt store it correctly....meaning it didnt go into the fridge at the right time etc. Oh sometimes if you dont pee enough to start off with hence mid stream, then it will have bacteria etc that you shouldnt have in it it will just be that so dont fret. Just annoying having to provide another sample with preg bladder
