A FBC (full blood count) isnt what it seems to be. It isnt a 'full blood test', but simply just the test for haemoglobin, red and white cells. Wont tell you much. Also doesn't include testosterone or anything else.
Normally a basic test in line with what you are after is:
Liver function, kidney function, cholesterol tg/hdl/ldl, glucse, testosterone, e2 and a FBC
