Checking for candida

Hi, would hearth screening help to check for candida?

I have had weird skin issues since 3 months ago, itchiness everywhere even my scalp, bumps showing up and disappearing then showing up again, dry skin patches, eczema on my mouth and hand, and im allergic to some food(which i have no idea which food) and im getting worried. I have taken antibiotics like doxycycline a few weeks back after this all started but before that (my lips were peeling) and a gp gave me antibiotics, not sure if it made all this happen or what.

I also have no idea what to do to check for candida overgrowth(my tongue seems to be white(?) But it has been like this since i can remember)

What is recommended if i do have candida? I live in singapore, will jarrows acv help?
