Hi Mary,We did the test through United Medical Labs in McLean, Va. Matia suggested that they were a good lab to use and you can just mail in the sample. We did an IC Broth Culture and a Candida Test - both of which are done on a semen sample (didn't have to do any urine or blood testing). All you have to do is get one of those sterile urine sample cups (like the ones you use at the doc's office) and then you just overnight the sample to the lab. i actually just packed it in the box that i usually get my natren probiotic supplements in. i just saved the ice pack and used it with the box/styrofoam that comes in it.as far as the type of bacteria, matia said it doesn't really matter, it's just the fact that it's there. guess they all kind of act in the same way in our bodies. when i first visited matia, she had asked about my husband's health and since he has crohn's and some other random health issues, she thought it was likely that he had an imbalance too which was probably contributing to my issues. i have never had any kind of classic allergic reaction to his semen and he has no symptoms like ours, so never occured to me that he could have any issue. but she said that it wouldn't necessarily be like an "allergic" reaction or immediate burning or anything. she just said that it could contribute to my overall imbalance which keeps me symptomatic. since starting on matia's regimen, we are really careful when we have sex, so as not to mix fluids. but, in the longrun of course, want to address this issue - especially if we try to get pregnant at some point. so, finally had him tested. would love to be able ot give you more info about protocols, but as you know that's what i'm still trying to find out! once i find all that out from matia, i will definitely post here to let you know.hope this info helps!
