Blood test is useful to diagnose pre diabetes, diabetes type 1, diabetes type 2 and gestational diabetes. Diabetes test is easier, faster, and less expensive to perform.
What is diabetes test?
Diabetes test is a simple blood test to diagnose diabetes or to monitor diabetes. Diabetes test is testing the glucose or sugar level in your blood or plasma.
Do you know one-third undiagnosed diabetes? International Diabetes Federation (IDF) estimates that globally about 183 million people, or half of those who have diabetes, are unaware of their condition; most of them type 2 diabetes. In sub-Saharan Africa, the proportion of people with undiagnosed diabetes can reach up to 90 percent. Even in high-income countries, about one-third of people with diabetes are undiagnosed. Earlier diabetes diagnosis and its management in time helps prevent harmful diabetes complications.
Diabetes screening criteria
A principle or standard by which diabetes screening has suggested this set of standard is diabetes-screening criteria.
Criteria for diabetes diagnosis are:
- More than two diabetes risk factors,
- Central obesity,
- Have had gestational diabetes,
- Already diagnosed as pre-diabetes,
- Presence of diabetes symptoms,
- Have hypertension or high blood pressure,
- Have hyperlipidemia or high blood cholesterol.
If you met most of the above-said criteria, then you need to undergo for diabetes screening.
Commonly used diabetes testing
- Fasting plasma glucose (FPG) test - this test is to measure blood’s plasma-glucose after fasting for at least 8 hours, thus the name fasting plasma glucose test. This test is useful to detect all types of diabetes.
- Oral glucose tolerance test (OGTT) - which measures blood glucose after 8 hours of fasting and 2 hours after the person drinks a glucose-containing beverage. This test is effective to diagnose all types of diabetes.
- Random plasma glucose test - also called a casual plasma glucose test, because there is no fasting required or worry about what we have eaten. This test, along with an assessment of symptoms, is used to diagnose diabetes but not pre-diabetes. However, once random plasma glucose test confirms diabetes needs to be reconfirming by FPG or OGTT.
Is A1C test reliable for diabetes diagnosis?
About one-third of people with diabetes are undiagnosed.
International Diabetes Federation (IDF) estimates that globally about 183 million people, or half of those who have diabetes, are unaware of their condition; most of them type 2 diabetes. In sub-Saharan Africa, the proportion of people with diabetes who are undiagnosed can reach up to 90 percent. Even in high-income countries, about one-third of people with diabetes are undiagnosed.
Earlier, a person is diagnosing as diabetes and managing it in time helps prevent harmful and costlier diabetes complications.
