Yes, but blood test show nothing in 98%, because candida in bloodstream mean you are almost dead. So, we have local overgrow (colon, small intestine, maybe stomach, i have in my throat too).
You could test your stool, but before you must eat only simple Sugar for two days to feed candida to show in your stool. So this is stupid. You have symptoms you have candida overgrow.
Change diet to high carb (Okinawa, Hunza diet - most healthy on World) or high fat (ketogenic diet - v. healthy) all must be balanced - PROTEIN keep under 14% calorie basis and around 0,8 up to maximum 1 gram per kilo body weight !!
