I would say you're OK on the urine test, but you can always double check next time you're at your GP- they can look up the results and confirm.
Obviously, if you have diabetes symptoms - excessive thirst, excessive urination, being very lethargic, infections that don't seemingly go away, weight loss, thrush -get thee to the GP faster!
On a side note, I don't know why they use urine testing for Diabetes- that's very outdated. Sure its a quick, painless (cheap!!) way to check - just a stick into the urine- colour change confirms sugar in the urine, but it's actually very far from clinical diagnosis of diabetes. Diabetes is confirmed by two separate fasting plasma (blood) glucose tests - over readings over 7 mmol/L (126 mg/dl) - the kidneys don't actually 'spill' glucose into the urine until your blood sugars are 10 mmol/L (180 mg/dl)
So I can only fathom they do this for both Diabetes - (meaning-come back in for further testing, I hope?) and for kidney function- Kidney disease is silent and many people don't realise they have it until its too late. You shouldn't have protein in your urine, so getting a dip stick finding protein in the urine is a key that something is awry there and needing further investigation.
Do GPs test for these regularly (mine doesn't) - or is it a 'one off' kind of thing? It should definitely be routinely (based upon your risk factors depends on how often) in my opinion.
And no, I'm not a medical professional -but Diabetes is a big research interest of mine, did lots and lots of research in it for my biomedical engineering masters degree, work in a Diabetes research/development/manufacturing company, and volunteer with Diabetes UK and Children with Diabetes
