Metabolic / Electrolytes
Also known as: Free calcium
No common urgent flag from this test alone
This test checks how much calcium is in your blood that is not stuck to proteins. This "free" calcium is very important. It helps make your bones strong. It also helps your heart work right. Your muscles need it to move. Your nerves use it to send signals. It even helps your blood clot.
Your doctor orders this test to look for issues with your bones, kidneys, liver, or parathyroid glands. It also helps them check on these problems and how well your treatments are working.
Normal value ranges can vary slightly among different labs. Always discuss your specific test results with your healthcare provider.
