A phosphate test measures the amount of phosphate in your blood. Your body needs this mineral to build and repair bones and teeth, help nerves function, and make muscles contract.
The kidneys help control the amount of phosphate in your blood. A high level of phosphate can be caused by a kidney problem.
This test may be done to check phosphate levels if you have kidney disease or bone disease. It helps find problems with certain glands, such as the parathyroid glands. The test is also used to find a cause for abnormal vitamin D levels.
Tell your doctor ALL the medicines, vitamins, and natural health products you take. Some may affect the test results. Your doctor will tell you if you should stop taking any of them before the test and how soon to do it.
A health professional uses a needle to take a blood sample, usually from the arm.
This test will take a few minutes.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to keep a list of the medicines you take. Ask your doctor when you can expect to have your test results.
