Blood tests to rule out Diabetes

Diabetes and Pre-diabetes only can be detected once the diagnosis report comes. There are types of blood tests to show whether the person's blood glucose level is higher than the glucose range. Blood tests help to identify the type of diabetes too. Doctors may ask people to go for blood tests to diagnose Diabetes

Type 1 Diabetes

Physicians often diagnose type 1 diabetes in children and young adults who are symptomatic of diabetes. Adults may experience symptoms that are less specific.

Type 2 Diabetes

  • Age 35 or older
  • Obese people
  • Women with gestational diabetes

Gestational diabetes: All pregnant women who have not previously been diagnosed with diabetes should be screened for gestational diabetes from 24 to 28 weeks of pregnancy.

Various blood tests to rule out Diabetes and Pre-diabetes -

  • Fasting blood sugar test -  This measures the level of blood sugar after a night of fasting. A fasting blood sugar level of 99 mg/dL or lower is normal, between 100 to 125 mg/dL indicates prediabetes, and 126 mg/dL or higher indicates diabetes.
  • Random blood sugar test -  In a random blood sugar test, the doctor checks blood sugar without taking into consideration the date of the last meal. This test, along with a symptom assessment is used to diagnose diabetes, but not pre-diabetes.
  • A1C - The A1C or HbA1c test is a simple blood test that measures mean blood glucose over the last three months. It is used to manage diabetes. The target for most adult diabetics is an A1C below 7%.
  • Glucose Screening Test -  It measures blood glucose at the time of the test. The person drinks a fluid that contains glucose. After an hour, the person's blood will be collected to check the blood sugar levels. The normal result is less than 140 mg/dL. If the level is above 140 mg/dL, a glucose tolerance test will be required.
  • Glucose Tolerance Test -  This measures the level of blood sugar before and after drinking and contains glucose. The results may vary depending on the size of the glucose drink and how often the glucose level is tested.
