Hypercalciuria is the condition of elevated
calcium in the urine
Urinary calcium is calcium in the urine. It is termed -calcuria or -calciuria as a suffix.

In a urinalysis, the normal amount of urinary calcium can be measured in amount per time (commonly per 24 hours). It can also be measured in a ...

Bone density, or bone mineral density, is the amount of bone mineral in bone tissue. The concept is of mass of mineral per volume of bone (relating to density in the physics sense), although clinically it is measured by proxy according to optic ...

Hypercalciuria in patients can be due to genetic causes.
