There are several noticeable symptoms of type 2 diabetes ranging from an intense feeling of thirst, exhaustion, and weight loss. Left untreated, it can lead to damaged blood vessels, nerves, and organs. There are two tests for diabetes – the glycated haemoglobin (GHT) and glucose tolerance test. The glycated haemoglobin test tells you your average level of blood sugar over the past two to three months. In most cases, blood is taken from an arm vein or finger. A glucose tolerance test determines where your body is having issues processing glucose. Similar to the GHT, a blood sample is taken and blood glucose is measured. Then, the patient is given a sweet drink and two hours later the glucose is measured again.
