Hi. Do you literally mean 10 hours after 7.30pm? If you do, the test has no value as the liver can dump glucose overnight. Even if you are diabetic don't assume to start with that you will need meds. If you are a potential overweight T2, then moving to a low-carb diet may be all you would need to do. Yes, do get some tests done; the local pharmacy will often do on-the-spot checks which are rough and ready but will highlight blood sugar that is a lot too high
