Arterial Blood Gas (ABG) Test: About Your Child's Test
What is it?
An arterial blood gases (ABG) test is a blood test. It measures the acid-base balance (pH) and the levels of oxygen and carbon dioxide in the blood. It uses blood drawn from an artery. This is where the levels of oxygen and carbon dioxide can be measured before they enter body tissues.
Why is this test done?
An arterial blood gases test is done to:
- Check for severe breathing and lung problems.
- See how well treatments for lung problems are working.
- Check for changes in how well your child's lungs, heart, or kidneys are working.
- Look for problems linked to diabetes.
How do you prepare for the test?
- Your doctor will tell you if there is anything your child will need to do to prepare for the test.
How is the test done?
- A health professional takes a sample of your child's blood. The blood is taken from an artery, usually on the wrist.
- The health professional will put a bandage over the puncture site and apply firm pressure for 5 to 10 minutes.
Follow-up care is a key part of your child's treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if your child is having problems. Ask your doctor when you can expect to have your child's test results.
For 24/7 nurse advice and general health information call Health Link at 811.
