  • Blood tests help doctors check for certain diseases and conditions. They also help check the function of your organs and show how well treatments are working.
  • Blood tests are very common. When you have routine checkups, your doctor may recommend blood tests to see how your body is working.
  • Some of the most common blood tests are a complete blood count (CBC), blood chemistry tests, blood enzyme tests, and blood tests to assess heart disease risk.
  • A CBC can detect blood diseases and disorders.
  • Blood chemistry tests measure different chemicals in the blood. These tests give doctors information about nerves, muscles (including the heart), bones, and organs, such as the kidneys and liver.
  • Blood enzyme tests measure the amounts of certain enzymes in your blood. These tests can help diagnose a heart attack.
  • Blood tests to assess heart disease risk measure substances in your blood that may show whether you're at increased risk for coronary heart disease.
  • Many blood tests don't require any special preparation and take only a few minutes. Other blood tests require fasting (not eating any food) for 8 to 12 hours before the test. Your doctor will let you know how to prepare for blood tests.
  • During a blood test, blood usually is drawn from a vein in your arm or other part of your body using a needle. It also can be drawn using a finger prick. Drawing blood usually takes less than 3 minutes.
  • Once the needle is withdrawn, you'll be asked to apply gentle pressure with a piece of gauze or bandage to the place where the needle was inserted. This helps stop bleeding. Most often, you can remove the pressure after a minute or two.
  • The main risks of blood tests are discomfort or bruising at the site where the needle goes in. These complications usually are minor and go away shortly after the tests are done.
  • Your doctor will get the results of your blood test(s) and discuss them with you. Blood tests show whether the levels of different substances in your blood fall within a normal range. Your doctor should discuss any unusual or abnormal results with you.
