Your doctor can diagnose diabetes, prediabetes, and gestational diabetes through blood tests diabetes tests taken from the blood that shows that your blood sugar (glucose in the blood), also known as Blood Sugar, is very high.
Your doctor can diagnose diabetes, prediabetes, and gestational diabetes through blood tests diabetes tests taken from the blood that shows that your blood sugar (glucose in the blood), also known as Blood Sugar, is very high.
If you feel that you may have diabetes, do not try to diagnose yourself by yourself. Test tools that you can buy over the counter, such as diabetes tests from blood glucose meters, cannot diagnose yourself with diabetes.
Who should be tested for diabetes?
Any person who has symptoms of diabetes should be screened for the disease. Some have no symptoms, but may have risk factors for diabetes and need to be examined.
The trial facilitates the doctor to quickly detect diabetes and work with their patients to manage diabetes and prevent complications.
Testing can also detect prediabetes. If you are overweight then changing lifestyles to lose a small amount of weight can help you delay or prevent type 2 diabetes.
Type 1 Diabetes Test
Doctors usually test those who clearly have symptoms of diabetes for type 1 diabetes. Doctors often test random plasma glucose (RPG) for the diagnosis of type 1 diabetes. This blood test shows your blood sugar levels at one point at a time. Sometimes doctors also perform a Blood Diabetes Test to find out how many days one has a high level of blood sugar.
Type 2 Diabetes Test
If you are 45 years of age or more, type 2 diabetes is more likely to develop, if you have a family history of diabetes or you are overweight, then you have more chances to get diabetes.
Physical inactivity, race, and some health problems such as high blood pressure also increase the likelihood of developing type 2 diabetes. If you have Gestational diabetes or you are pre-diabetic, you may have type-2 diabetes.
Type 2 diabetes is one of the many reasons, including
- Overweight and Obesity
- Not physically active
- Insulin Resistance
- Gene
Pregnancy Diabetes
Gestational Diabetes is a type of diabetes that occurs only during pregnancy, gestational diabetes can cause health problems both in mother and child. Managing your diabetes can help protect you and your child.
Diagnose diabetes and prediabetes
Doctors often use fasting plasma glucose (FPG) tests or A1C tests to diagnose diabetes In some cases, they can use a random plasma glucose (RPG) test.
Fasting plasma glucose (FPG) test
Your Blood Sugar levels are observed for one in the FPG blood test. For the most reliable result, it is best to test it in the morning after having an empty belly for at least 8 hours in the morning fasting means that nothing is eaten except water.
A1C Exam A1C Test
The A1C test is a blood test that indicates glucose levels in your average blood in the last 3 months. Other names for A1C testing are hemoglobin A1C, HBA1C, glycated hemoglobin, and glycosylated hemoglobin tests. You can eat and drink before this diabetes test. When it comes to using A1C to diagnose diabetes, your doctor will consider factors like your age and testing A1C is not correct if you have anemia or any other problems with your blood.
Your health care professional will report your A1C test result as a percentage, such as 7 percent a1C, the higher the percentage your average blood sugar levels will be.
People with diabetes also use information from a 1C test for the management of diabetes.
Random Plasma Glucose (RPG) Test RPG test
Sometimes health doctors use RPG tests to diagnose diabetes when symptoms of diabetes are present and they do not want to wait until fasting. You don’t need overnight fast for the RPG test. You can do this blood test at any time.
Tests to diagnose gestational diabetes
Glucose challenge or oral glucose tolerance test or both may be used in pregnant women to test gestational diabetes. These tests show how well your body is able to use glucose.
Glucose Challenge Test
If you are pregnant and health care professionals are checking you for gestational diabetes, you can first test the glucose challenge. Another name of this test is the glucose screening test. In this test, a health care professional first drinks you with a sweet liquid containing glucose, after 1 hour takes your blood sample. You do not need to fast for this test. If glucose is too high in your blood- 135 to 140 or more- you may need to undergo an oral glucose tolerance test (OGTT).
Oral Glucose Tolerance Test (OGTT)
Blood Sugar is tested after at least 8 hours of fasting at OGT, first of all, a health care professional will take a sample of your blood and then you will have to drink a drink containing glucose. To diagnose gestational diabetes, you will need to give a blood sample every hour for 2 to 3 hours.
High Blood Sugar levels during the time of any two or more diabetes tests during 1 hour, 2 hours, or 3 hours means that you have gestational diabetes. Your health care team will tell you what the results of your OTG mean.
Doctors can also use OGT to diagnose type 2 diabetes and prediabetes in people who are not pregnant. OGT helps the doctor to detect type 2 diabetes and prediabetes better than the FPG exam. However, OGT is a more expensive test and is not easy.
What is the range of diabetes and Prediabetes
Each test uses a different measurement to detect diabetes and prediabetes. Usually, a single test method is required to be repeated twice a day to diagnose diabetes. Your doctor may use the second exam method to confirm if you have diabetes
If you are not pregnant, the following table will help you understand this:
