Let’s talk about how to diagnose and treat a vaginal yeast infection. So if you have itching, burning white discharge, and you’re concerned that you have an infection in your vagina, you definitely need to see your healthcare provider to make sure that it’s nothing worse than a vaginal yeast infection. But if you’re determined to have most likely a vaginal yeast infection, your doctor will do a swab of the vagina looking specifically for high Fe or evidence of vaginal yeast that usually has to be sent away. Sometimes the doctor can do it on the spot, but most of the time it goes to the lab and it comes back. And it determines if you have an overgrowth of vaginal yeast or candida albicans, which is the most common form of a vaginal yeast infection.
