Diagnosis of Diabetes

Reading time: 2 min

Diabetes is diagnosed by means of a blood test that determines a person’s blood sugar (glucose) levels. Normal blood glucose values range between 70 and 100 mg/dL.

This test analyses whether the analytical indicators are:

  • After fasting: equal to or higher than 126 mg/dL, in two measurements.
  • At any time of the day: equal to or greater than 200 mg/dL accompanied by characteristic symptoms, such as an increased need to urinate or excessive thirst.
  • After taking a glucose solution (75 g): above 200 mg/dL. This test is carried out on individuals whose glucose levels after fasting are between 100 and 126 mg/dL.
  • Glycated hemoglobin (HbA1c): equal to or higher than 6.5%.
