Overview of the Calcium Blood Test
The Calcium Blood Test measures the amount of calcium circulating in your bloodstream. Calcium is one of the body's most important minerals and is essential for maintaining healthy bones and teeth, normal muscle contraction, nerve signalling, blood clotting and heart function.
This is a single-biomarker mineral test that measures Calcium. Although approximately 99% of the body's calcium is stored in bones and teeth, the small amount circulating in the blood is carefully regulated by hormones, the kidneys, vitamin D and the digestive system. Measuring blood calcium can provide valuable information about calcium balance and overall health.
People may choose this test as part of a routine health assessment, to investigate symptoms that could be associated with calcium imbalance, to monitor previously identified calcium abnormalities or to support the management of conditions affecting bone, kidney, thyroid or parathyroid health under the guidance of a healthcare professional.
Blood calcium levels can be influenced by several factors, including hydration, albumin levels, medications and hormone activity. Results should always be interpreted alongside symptoms, medical history, other laboratory findings and professional clinical assessment.

Understanding Your Results
