Service Providers for Serum Calcium
The serum calcium test measures the amount of calcium in the blood, which is essential for bone health, muscle function, and nerve signaling. Preparation typically involves fasting for 8-12 hours. During the test, a blood sample is drawn from a vein. The results are interpreted by comparing calcium levels to the normal range; high or low levels can indicate conditions like kidney disease, osteoporosis, or hyperparathyroidism. Risks include slight pain or bruising at the blood draw site. Certain factors, like medications or vitamin D levels, may affect the results.
