Diabetes screening tests are done to diagnose diabetes in the early stage. Early diagnosis and treatment can prevent or delay complications due to diabetes. The diabetes screening tests that are done include;
Urine glucose test (sugar in urine): If sugar (glucose) is present in the urine it is called glycosuria or glucosuria. Normally glucose is not found in urine. Presence of sugar in urine may indicate diabetes. If glucose is detected in your urine your doctor may recommend further test like blood test (to test for blood glucose levels).
Fasting plasma glucose (FPG): This test measures blood glucose level in the morning (after 8 hours of fasting) before you eat or drink anything even tea or coffee. The test can help to diagnose diabetes and pre-diabetes.
Diagnosis based on fasting plasma glucose
If the test results are abnormal your doctor will repeat the test on a different day. In addition he or she may recommend other tests to confirm the diagnosis of diabetes.
