Blood Test For Diabetes Patients

Diabetes patients can be suggested to have routine blood tests. This is decided on the basis of their glucose level. We will be discussing the blood test for diabetes in detail. Based on different tests, the statistical numbers for a healthy person have been given. On the basis of the present data, tips for controlling diabetes and keeping the person healthy are suggested.

Diabetes patients can have mainly three types of diabetes. These are Type1, type 2 and gestational one. In all of the cases, the patient’s body stops making or using insulin.

Types of Diabetes

Type1 Diabetes

The pancreas of the person stops producing insulin in this condition. It does not show any specific symptoms. It is diagnosed only after a significant increase. This condition can develop due to different reasons. It may be family history, reduced size of pancreas and infection in pancreases.

Type2 Diabetes

The patient’s body can’t use the insulin produced in this condition. The problem is also named as insulin resistance. The main risk factors are obesity, gestational diabetes, family history, age, and reduced glucose tolerance. In the U.S, this is affecting children also due to an unhealthy lifestyle.

Gestational Diabetes

 Diabetes Patients

This is related to pregnant women showing diabetic symptoms. This type of diabetes leads to type2 diabetes at a later stage in life. Similar to type2, the main cause of this is again overweight.

For the diagnosis of all types of diabetes, blood and urine tests can be performed. Urine test is not the preferred choice for type 2 patients. Because urine tests can only identify higher sugar levels in the body. Thus, blood tests are the preferred choice.

Blood Test for Diagnosis

To identify the sugar level in the body, the following tests are considered:

1. Haemoglobin A1c Test

A1c is the blood test that measures the average glucose level in the blood. In this, the blood is taken from the finger or vein of the arm of the diabetes patients. This is not like the regular home test for diabetes. Checking at home gives the result in a moment only. In this case, the blood samples are then sent to the lab which follows NGSP rules for testing. Hence it is time-taking as well. This test considers the past 3 months and shows the average. This is the first choice for most of the cases. Hence, this test is also referred to as the primary diagnosis.

  •  Sugar level ranges from 5.8 to 6.4 % reveals the development stage. The person is more likely to have type2 diabetes later in life.
  • Sugar level higher than 6.5% has already turned into diabetes patients. The person is advised to follow medical advice.

2. Fasting Plasma Glucose Test

This test is also named as FPG. As the name suggests, a person should not eat or drink anything. A person should not take anything 8 hours before the test. In most of the cases, the test is conducted early morning. The blood sample is collected from the finger with the finger stick test. The other way is to collect from the arm vein in a vial.

The test is performed for diagnosing diabetes patients suffering type2 and prediabetes. In addition to this, the A1c test can also be performed to get more accurate results. Further, the results can be analyzed as below:

  • Glucose levels lower than 100mg/dl are treated as normal.
  • The glucose level from 100 to 125 mg/dl shows the chances of developing.
  • Value more than 126 mg/dl suggests regular medicines for diabetes.

3. Oral Glucose Tolerance Test (OGTT)

This test is conducted every two hours interval. The blood sample is collected with fasting first. Following that, the patient is asked to have a glucose syrup. After two hours the blood glucose is checked again. Test results below 140 mg/dl are treated as normal. On the other hand, above two 200 mg/dl are the diabetes case.

A study shows the success rates of the A1C test alone. It missed 73% of the diabetes patients at first. Therefore, it is further identified with OGTT.

4. Random Plasma Glucose Test

Without fasting, the glucose level can be checked with the RPG test. The blood sample can be taken at any time during the day. In this case, eating history is not checked.

  • Readings more than 200 mg/dl approves that you should consult the doctor.
