Phosphate in Blood: About Your Child's Test
What is it?
A phosphate test measures the amount of phosphate in your child's blood. Your child's body needs this mineral to build and repair bones and teeth. It also helps nerves and muscles work as they should.
The kidneys help control the amount of phosphate in the blood. A high level of phosphate can be caused by a kidney problem.
Why is it done?
A test to measure phosphate in blood may be done to:
- Check on phosphate levels if your child has kidney disease or bone disease.
- Help find problems with certain glands. This could include the parathyroid glands.
How do you prepare for the test?
In general, you don't need to prepare before your child has this test. Your doctor may give some specific instructions.
How is the test done?
A health professional uses a needle to take a blood sample, usually from the arm.
How long does the test take?
This test will take a few 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.
