Everytime my urine gets set to lab for testing it keeps coming back as mixed growth.. over 7 samples have all come back the same over many months. i mean come on they keep asking for it to be repeated so why havent they found out what it is yet.. now i know this is too much information but its got to a point now that no matter how much i wash i still cant get rid of the odour down below and its getting quite depressing. what does this mix growth mean? please somebody help..
