What Happens During the Test?

Content: Your doctor may also want you to get a phosphate test if they suspect: Issues with diabetes
Hormone imbalances, such as Vitamin D or PTH, a hormone that helps balance calcium and phosphorus in your body
Malnourishment
Since phosphate works so closely with calcium, doctors also use the test to determine whether your body is getting and using calcium the right way. Issues related to calcium can be a sign of low vitamin D, or they may include: Bone problems
Feeling very tired
Muscle weakness
Cramping
How Should I Prepare for It? Your doctor will give you instructions; follow them carefully. You may be asked not to eat anything from midnight before the test until after the test is over. Make sure your doctor knows about everything you're taking, including prescription and over-the-counter medicine, herbal supplements, vitamins, and recreational or illegal drugs. What Happens During the Test? After cleaning the skin on part of your arm, a technician will insert a needle into one of your veins.
