Some necessary tests of diagnosing diabetes

Diagnosing diabetes a1c Diabetes is one of the diseases that have subtle signs and symptoms. It is quite hard to say that someone has contracted diabetes without he or she takes the test. There are some ways of diagnosing diabetes that are suggested by the World Health Organization (WHO). It is said that each way should be repeated on the following day to diagnose the diabetes.

The test which you need to take should be conducted in a health care setting. If through the test the doctor says that you have a very high glucose level or if you have classic symptoms of high blood sugar in addition to one positive test, you may not need to take a second test to be diagnosed with diabetes. The test includes these three steps:

A1C

The A1C test is aimed at measuring your average blood glucose in a specific period of time. Usually, it determines the level of your blood sugar for the past two or three months. This step of diagnosing diabetes does not require you to fast or drink anything. It means that you can directly take this test. As the minimum requirement for people who are diagnosed with diabetes is when the A1C test result is greater than or equal to 6.5 percent. The normal level of blood sugar is found when the result of A1C is less than 5.7%. It means that when the result of your A1C test is between 5.7% and 6.4%, you are already in the gray area of normal and diabetic blood sugar level.

Fasting Plasma Glucose (FPG)

This particular step of diagnosing diabetes is testing the level of your fasting blood glucose. As the name suggests, you are not supposed to eat or drink anything for at least eight hours before you take the test. You can still drink water though. Thus, the test is commonly done early in the morning, even before you have your breakfast. It is because during the night you do not eat or drink anything when you are sleeping. If the result of your test shows that the level of fasting blood glucose is greater than or equal to 126 mg/dl, it means that you are considered diabetic. The normal range of fasting blood glucose is supposed to be less than 100 mg/dl, which means that the pre-diabetes condition lies between 100 mg/dl to 125 mg/dl of fasting blood sugar level.

Oral Glucose Tolerance Test (OGTT)

This test is another step of diagnosing diabetes. It is a two-hour test which aims at checking your blood glucose level before and two hours later after you drink a specific sugary drink. Through this test, the doctor can understand how your body metabolizes glucose. You are considered diabetic if the result of this two-hour test reaches greater than or equal to 200 mg/dl. Two-hour blood glucose level reaches between 140 mg/dl and 199 mg/dl is indicating pre-diabetes condition. Meanwhile, if the result is lower than 140 mg/dl, your glucose metabolism is considered normal.

Random Plasma Glucose Test

Besides three kinds of tests that are explained previously, you can also take random plasma glucose test when you think that you have experienced severe diabetes symptoms. This test can be taken any time.
