what did your test show? you should keep all the copies of your test for your records.
test show your white blood cell counts and your vitamin D levels. vit D and white cells fight yeast in the body. I think there something else going on in your body stopping the body from getting rid of your yeast infection. things that interfere with immune system are infections(dental,parasitic,bacterial,viral), bad diet, stress, birth control, Antibiotics .
see if you can get print outs of your numbers for your white bloods cells, vitamin d and other vitamin levels to see why the yeast isnt leaving.
