What is this test?
This test measures the level of phosphorus in your blood. Phosphorus is a common mineral found in the food you eat. It's also found in teeth and bones.
Having a high or low level of phosphorus in your bloodstream can signal a number of health conditions. Most commonly, a high level of phosphorus is related to a kidney disorder. It shows that your kidneys are having difficulty clearing phosphorus from your blood. A high level of phosphorus can also mean uncontrolled diabetes and other endocrine disorders.
Why do I need this test?
You may need this test if your healthcare provider suspects that you have a kidney disorder. You may also need this test if you are having trouble controlling your diabetes. You may need this test if you have symptoms of kidney disease, including bone problems, fatigue, and weakness, but you may not have any symptoms at all.
