Diagnosing diabetes through blood tests
It is suspected by the eye specialist that my 79 year old mother has diabetes, because an angiogram of the eye shows that persistent blurred vision is caused by leaking blood vessels round the macula area. Her GP sent her for 3 tests: 2 sugar and 1 cholestrol. She was told to fast from 10 the night before. 3 vials of blood were taken and the one sugar test had a slighltly elevated result: 6.54. The other apparently was within normal bounds. She was NOT given any glucose before the blood was drawn, as the news24 articles suggest she should have been given. And certainly not retested a few hours later. Should this have been done? Does this mean she definitely does not have diabetes or is there cause for further investigation?

GW, the test you’re referring to is called a glucose intolerance test. It is indicated for people that have a fasting blood sugar of higher than 6.5 and lower than 11.1. You can have it done at any of the chemical pathology labs. Good luck.
