This test measures Calcium levels in the blood. Calcium is a mineral which is important for healthy functioning of the heart, muscles and nervous system as well as proper bone formation. The body will pull calcium from the bones to maintain blood levels when a person is not ingesting enough calcium or has a disorder which prevent proper absorption.
Calcium testing is frequently part of a general health screening. It may also be ordered when someone has kidney disease, thyroid disease, cancer, malabsorption or malnutrition.
This test measures total calcium levels which include both free and bound. An Ionized Calcium Serum test is available for those who wish to only measure the free or unbound portion of calcium.
Turnaround time for the Calcium blood test is typically 1 business day.
Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
Calcium blood testing prefers fasting for 12 hours prior to going to the lab.
