The calcium/creatinine ratio is measured in the urine specimen taken on the 400-mg calcium-restricted diet and in the fasting and post–calcium load samples. In healthy people, the calcium/creatinine ratio is no more than 0.11 for the fasting sample and no more than 0.20 for the post–calcium load sample.
