There is a test called the FPG (fasting plasma glucose test) which can determine if you have diabetes. This test can be performed by your doctor. There are two other tests that can be performed as well. http://diabetes.niddk.nih.gov/dm/pubs/diagnosis/
No enzyme is used to diagnose diabetes .People with diabetes have sugar in their urine. There is a test strip indicator which contains chemical indicators , if glucose is found in the urine the indicator changes color.
The renin stimulation test is performed to help diagnose and distinguish the two forms of hyperaldosteronism.
A fasting blood glucose test (FBC) measures the amount of glucose in your blood after you have not eaten for at least 8 hours. This test is commonly used to diagnose diabetes or monitor blood sugar levels in individuals with diabetes. High levels of glucose in the blood can indicate diabetes, while low levels can be a sign of hypoglycemia.
There are several blood tests that can diagnose diabetes. The most common is a fasting blood glucose test, where the glucose level is measured after at least eight hours of fasting. The blood glucose can be measured without fasting, but it can only diagnose diabetes, not prediabetes. The oral glucose tolerance test monitors how a body responds to an influx of glucose. After fasting for a least 8 hours, blood glucose levels are measured before and every 30-60 minutes after the ingestion of a glucose beverage for three hours. A urine test for high levels of glucose and ketones can help diagnose diabetes, but these results are not enough on their own.
Prothrombin time
The A1C test is a blood test that measures your average blood sugar levels over the past two to three months. It is primarily used to diagnose and monitor diabetes. An A1C level of 6.5% or higher typically indicates diabetes.
Insulin is used to monitor the levels of blood sugar in diabetics. It can be diagnosed with a blood test.
The following tests are used for diagnosis:A fasting plasma glucose (FPG) test measures blood glucose in a person who has not eaten anything for at least 8 hours. This test is used to detect Diabetes and pre-diabetes.An oral glucose tolerance test (OGTT) measures blood glucose after a person fasts at least 8 hours and 2 hours after the person drinks a glucose-containing beverage. This test can be used to diagnose diabetes and pre-diabetes.A random plasma glucose test, also called a casual plasma glucose test, measures blood glucose without regard to when the person being tested last ate. This test, along with an assessment of symptoms, is used to diagnose diabetes but not pre-diabetes.Test results indicating that a person has diabetes should be confirmed with a second test on a different day.
Diabetics need to have great hygiene when checking their blood. The area where the blood sample will come from must be wiped with sterile antiseptic wipes, which should be disposed after each use. This reduces the possibility of skin infection and contamination.
There are a number of different tests that are used for the diagnosis of diabetes. Regardless of the type of glucose test that is done, there should be a second one performed on another day.
A 2-hour postprandial test is a blood sugar test that measures glucose levels 2 hours after a meal. It is used to assess how the body responds to sugar intake and can help diagnose diabetes or monitor blood sugar control in individuals with diabetes.
