What tests to get in Europe?



Dear all,

I wonder what tests you would recommend to get that are available in Europe.
I have had the standard blood tests ordered by my GP but I would like to go a step further now
I have seen that redlabs (redlabs.be) has a request form with a list of tests

I wonder which ones would be a good starting point. Which ones are most likely to guide treatment. Something I am interested in is heavy metals but any recommendation of tests from this or other labs would be great.
