To diagnose diabetes, not only relying on clinical diagnoses based on signs on the patient's body but also need to combine with diabetes tests, thereby enhancing the diagnostic value and determining the condition exactly.
This test includes what is a question not everyone understands to be able to prepare carefully before the test. This article will help you learn more about this issue.
What Is The First Sign Of Having Diabetes?
To understand the importance of a diabetes test and when to see a specialist for this test, we need to understand what diabetes is and the signs to find out early. the first stage, in order to bring the most positive treatment effect.
Diabetes, also known as diabetes, is a metabolic disorder involved in the consumption and use of sugar in the body.
When the pancreas does not produce enough of the hormone insulin needed by the body, or when the body is resistant to insulin (no longer responds to the effects of insulin), it leads to a high level of sugar in the body the blood. causing dangerous complications for the body, especially the cardiovascular system.
Diabetes is a chronic disease, there is no definitive treatment. Therefore, it is very important to detect the disease early to have good control of the disease.
You should go to the hospital to diagnose diabetes when you have the following suspicious signs:
- Blurred vision.
- Always feel tired.
- Feeling hungry, even though you are full.
- Wounds or sores in the skin take a long time to heal.
When To Check Your Blood Sugar?
The following risk subjects should also have regular diabetes checkups including:
- People entering middle age, usually 50 years or older.
- People who are not physically active.
- Overweight, obese.
- Family history of type 2 diabetes.
- Women who have had gestational diabetes.
Pre-diabetes is diagnosed when the patient experiences one of the following disorders:
- Impaired fasting glucose (IFG): The fasting plasma glucose index ranges from 100 (5.6 mmol / L) to 125 mg / dL (6.9 mmol / L).
- Impaired glucose tolerance (IGT): The plasma glucose level measured at 2 hours from the 75g oral glucose test is between 140 (7.8 mmol / L) and 199 mg. / dL (11 mmol / L).
- The HbA1c index results ranged from 5.7% (39 mmol / mol) to 6.4% (47 mmol / mol).
Although this glucose disorder is not enough to provide a basis for a diagnosis of diabetes, this would be an implication of the person's risk of developing diabetes, also known as prediabetes.
What Is A Diabetes Test Included?
When there are signs of doubt, the patient should visit a hospital to get an accurate diagnosis of the condition. After the examination, depending on the specific case, the doctor will prescribe the patient to perform the most suitable types of diabetes tests.
These types of tests will have different results and timing of use, as follows:
1. HbA1c test
In the quantitative HbA1c test, the HbA1c index will reflect the average blood glucose concentration in the past 3 months.
The HbA1c index is an important basis for assessing the amount of glucose attached to red blood cells (hemoglobin, the oxygen-carrying protein in red blood cells) in the patient's blood.
This is also a test often prescribed by doctors in case of needing to diagnose and monitor the effectiveness of treatment for patients with type 2 diabetes.
For the most accurate results, this type of test is not available everywhere, only international standard testing centers can guarantee results.
The normal value of HbA1c is always lower than 5.7%. But the higher the blood sugar, the more hemoglobin with sugar comes with the following risks:
- HbA1c levels ranging from 5.7–6.4% indicate pre-diabetes.
- HbA1c levels ranging from 6.5% or more indicate that the patient has diabetes.
2. Random blood sugar test
As the name implies, a random blood glucose test through a patient's blood sample will be taken at a random time, not related to the patient's meals.
In the case of random blood sugar equal to or higher than 200 mg / dL (11.1 mmol / L), you have diabetes.
3. Fasting glucose plasma test
How long does fasting diabetes test? For a fasting blood glucose test, the amount of blood glucose should be measured when the patient is fasting for at least 8 hours.
Therefore, before testing, patients are often told ahead of time what matters to consider. Accordingly, the ideal time to conduct the test is early in the morning, when the patient has not eaten, because at this time, for normal people, blood glucose levels will decrease when the body is not supplied with external energy.
If the resulting glucose concentration increases at this time, it also means that the glucose metabolism disorder is going on in the patient's body.
The results of the glycemic index will fall into one of the following cases:
- Fasting blood sugar <100mg / dL (5.6 mmol / L): normal.
- A fasting blood glucose level between 100 mg / dL and 125 mg / dL (5.6–6.9 mmol / L): This person has prediabetes or impaired glucose tolerance. It may take a second time to check the results.
- Fasting blood glucose level> = 126mg / dL (7 mmol / L): This person has diabetes.
4. Oral glucose tolerance test
For the oral glucose tolerance test, the patient should also be careful of fasting overnight so that fasting blood sugar can be measured.
During the test, the doctor measures the patient's blood sugar. Next, the doctor will give you a drink of sugar, usually, about 200mL of water has been mixed with 75g glucose. Then blood sugar will be measured 2 hours from the time of taking it.
The results of the diagnosis of an oral glucose tolerance test are as follows:
- Result of glucose concentration <140mg / dL (7.8 mmol / L): Normal.
- Glucose results ranged from 140–199 mg / dL (7.8–11.0 mmol / L): Synonymous with prediabetes.
- Results for glucose concentration> 200 mg / dL (11.1 mmol / L): Shows that the patient has diabetes.
5. Get a diabetes test through a urine sample
Usually, for a urine test, a doctor will not prescribe it to diagnose diabetes. However, this is the test used when a doctor suspects a patient has type 1 diabetes.
The mechanism of ketone production is based on the case the energy is taken from adipose tissue instead of sugar in the blood. If the results of this test show that the body produces a large number of ketones found in the urine, this will provide a basis for suggesting the body is not making enough insulin.
6. Get tested for gestational diabetes mellitus
Gestational diabetes is also possible during pregnancy. Therefore, pregnant mothers should not be subjective before the signs of disease. Your doctor will consider assessing your risk factors for diabetes as follows:
If a person at moderate risk of gestational diabetes has a high sugar urine test, you should be screened for gestational diabetes between 24-28 weeks of pregnancy.
If a person is at risk of gestational diabetes, if you are overweight or obese during pregnancy, or had gestational diabetes during a previous pregnancy, have a family history of diabetes, your doctor should check for diabetes every day from your first prenatal visit.
Where Is Diabetes Tested?
How long does a diabetes test take place? Usually, after a blood sample is taken, it will be immediately sent to a testing center for analysis. If it is fast, about 24 hours will get results. But this time depends on where the test is done, so it can take a few days.
How much does a diabetes test cost? It is difficult to say exactly what the cost of a diabetes test is. Because each testing center, the hospital has a different technical machine, a team of specialized doctors, so there is a difference in prices.
In addition, this price depends on the initial diagnosis process, from which the doctor can advise and specify the appropriate test for each subject. However, you do not need to worry too much because this cost ranges only a few hundred for a test, not too high for proactively protecting the health and detecting diabetes early.
