Glucose Tests

Glucose tests measure the level of glucose in your blood or detect glucose in your urine.

A few different protocols may be used to evaluate glucose levels:

  • Fasting blood glucose (commonly called fasting blood sugar)—this test measures the level after a fast of at least 8 hours.
  • Random blood glucose—sometimes your blood glucose will be measured when you have not fasted (randomly).
  • A glucose tolerance test measures glucose levels after fasting and after you drink liquid containing a specific amount of glucose (see Glucose Tolerance Test).
  • A specific protocol is used to help diagnose gestational diabetes, which is diabetes that first develops during pregnancy (see Glucose Tests for Gestational Diabetes).
  • Urine is routinely tested for glucose as part of a urinalysis.
Heart Attack and Acute Coronary Syndrome

Acute coronary syndrome (ACS) may present as a heart attack or unstable angina, which are conditions associated with decreased blood flow to the heart. ACS can cause a spectrum of signs and symptoms. According to the Centers for Disease Control and Prevention, about 805,000 Americans have heart attacks each year. In the United States, someone has a heart attack every 40 seconds. Learn the symptoms, risk factors, and related lab tests in the article on Heart Attack and Acute Coronary Syndrome.
