Description : An 16-year-old man presents with polyuria and polydipsia. Which of the following may confirm the diagnosis of diabetes mellitus? 1) A random plasma glucose of >7.5 mmol/L 2) A finding of 3+ ketonuria 3) An HbA1c of 7.0% 4) A fasting plasma glucose of 7.5 mmol/L 5) An abnormal glucose tolerance test
Last Answer : Answers-4 The diagnosis is usually relatively easy to confirm in a symptomatic subject. A random glucose of >11.1 mmol/L or a fasting glucose of >7.0 mmol/L would be regarded as ... haemoglobin (HbA1c) is also highly suggestive but not diagnostic.
