A simple Blood Test that is conducted at any Laboratory can help determine if you have Diabetes.
In type 1 diabetes, symptoms are often sudden and can be life-threatening; therefore it is usually diagnosed quite quickly. In type 2 diabetes, many people have no symptoms at all, while other signs can go unnoticed being seen as part of ‘getting older’.
Common symptoms include:
The following primary tests can be conducted to diagnose diabetes:-
You will need 2 elevated glucose readings or one of the above IF YOU HAVE NO SYMPTOMS
If YOU HAVE SYMPTOMS (thirst, weight loss,excess urination) and a high sugar then one high reading is enough to diagnose diabetes.
SYMPTOMS + ONE HIGH READING = DIABETES
NO SYMPTOMS + TWO HIGH READINGS = DIABETES
NOTE: If you do take any two of the primary tests it is advisable to take a second confirmation test such as a HBA1C (glycated haemoglobin) or a OGTT (Oral Glucose Tolerance Test).
This test provides an average of your blood glucose reading for the last 2 / 3 months. It is a good indicator of (i) confirming if you have Diabetes and / or (ii) informs a Physician the risk of a Diabetic patient developing complications. The table below gives will help you interpret the HBA1C results.
The Oral Glucose Tolerance Test measures how your body responds to sugar (Glucose). This test is used to screen for pre-diabetes, type 2 diabetes and / or gestational diabetes. The Doctor will advise you on whether you need this test and you will be instructed NOT to eat, or drink certain fluids for up to 8-12 hours before the test. In addition to the above your Doctor may review your medications which could affect the test results and they will advise accordingly.
During the OGTT test, blood samples will be taken to measure the blood glucose levels in the body. A 1st sample will be taken and then you are given a sweet tasting glucose drink. Further blood samples are taken at 30 minute, one hour / or two hour intervals.
