Background: Calculation of the fractional excretion of calcium (FECa) from 24-hour (24h) urine collections is recommended to identify patients with suspected familial hypocalciuric hypercalcemia (FHH) during the work-up of primary hyperparathyroidism (pHPT). The current study was designed to test whether calculating the FECa or calcium-to-creatinin clearance obtained from 24h urine specimen can be substituted by results obtained from second morning or spontaneous void urine sa...
