Bone Densitometry
A bone-density test is a way to measure the strength of your bones. The main reason to have the test is to find and treat serious bone loss, called osteoporosis, and prevent fractures and disability.
Phosphorus
This test is ordered to see how much phosphorus is in your blood. Kidney, liver, and certain bone diseases can cause abnormal phosphorus levels.
PTH (Parathyroid Hormone)
This test is used to help identify hyperparathyroidism, to find the cause of abnormal calcium levels, or to check the status of chronic kidney disease. PTH controls calcium and phosphorus levels in the blood.
