Thanks. My blood test results seem to be in the normal ranges, although creatinine is slightly low but apparently that could be a consequence of low muscle mass, and possibly a diet low in protein, and that makes sense. It's the higher numbers that can indicate a problem, so I'm not overly worried I have my appointment with the GP next week so I can have it explained better. Still not happy with the urine test, but I suppose it is a sure sign that my GP cannot give me the OK with a normal FBG, especially if i present my own readings.
