Understanding Calcium Spot Urine
What is Calcium Spot Urine?
The Calcium Spot Urine Test evaluates if high calcium levels in urine have led to kidney stones. It can also help assess if the dietary intake of calcium is high enough or if the intestine is absorbing enough calcium.
To prepare for the Calcium Spot Urine Test, your doctor might advise you to stop taking medication like potassium citrate or thiazides that might affect the test result. Your doctor might also ask you to follow a specific diet with a certain calcium level for a certain number of days leading up to the calcium urine spot test. An individual with a normal diet may have 100 to 300 mg/day calcium in the urine. Above 300mg/day is considered abnormal.
