Serum Calcium (with Sacrum/Coccyx Index or Related Metabolic Assessment)

Your provider may order this test to help find the cause of symptoms such as ongoing pain, an injury from a fall or accident, or unexplained changes in your bones. It can confirm or rule out a fracture, check how a healing injury is progressing, or look for signs of infection, arthritis, or other conditions affecting the skeletal system.

Your doctor may request this test if you have symptoms like muscle weakness, bone pain, or conditions affecting calcium metabolism (e.g., kidney disease, vitamin D deficiency). They may also check sacrum/coccyx-related issues like spinal abnormalities or metabolic bone disorders.

Preparation is usually simple. You may be asked to remove jewelry, glasses, or clothing with metal and change into a gown so the images are not blocked. Tell the technologist if you are pregnant or think you might be, and bring a list of your current medications. In most cases you can eat, drink, and take your medicines as usual before arriving.

No special preparation is needed, but avoid eating or drinking for 8–12 hours before if fasting calcium is required. Bring your medical history and any medications to your appointment.

A radiologist will review your images and send a report to your provider, usually within a few days. The report can show a fracture, dislocation, arthritis, bone loss, infection, or a growth, or it may be normal, which can help rule out certain problems. Your provider will explain the findings and discuss whether you need treatment, additional testing, or follow-up imaging.

Calcium results alone don’t directly assess sacrum/coccyx health, but abnormal levels may signal broader metabolic or skeletal concerns. Your doctor will interpret results with clinical context.

This test is often used to keep track of conditions such as fractures and stress injuries, osteoarthritis and other degenerative joint disease, osteoporosis, bone infections, and benign or cancerous growths. It may also be repeated over time to see how well a broken bone is healing or how a known condition is responding to your treatment plan.

This test helps diagnose or monitor conditions like hypocalcemia (low calcium), hypercalcemia (high calcium), osteoporosis, or metabolic bone diseases. Sacrum/coccyx-specific issues (e.g., coccygeal fractures) may require imaging.
