Background: PHPT is often overlooked/underdiagnosed. Several strategies (biochemical markers alone or combined in complex algorithms) have been investigated to easily diagnose/screen PHPT, but PHPT diagnosis remains challenging at present, especially in asymptomatic patients. As serum calcium (Ca) and phosphorous (P) are inversely related in PHPT, the Ca/P ratio could be a good candidate tool for PHPT diagnosis. Surprisingly, no literature data on Ca/P ratio are available, des...
