Calcium Creatinine Clearance Ratio is used to differentiate familial hypocalciuric<unk>  from primary hyperparathyroidism, ratio < 0.01 suggestive of FHH and > 0.01 suggestive of primary hyperparathyroidism. Calcium creatinine clearance ratio = [24-hour urine Ca  x  serum Cr]  ÷  [serum Ca  x  24-hour urine Cr].
