Clinical Interest
Urine Calcium measurement measures the amount of calcium excreted in the urine.
It helps to differentiate hyperparathyroidism from other causes of hypercalcaemia, such as familial hypocalcaemic hypercalcaemia (FHH), where blood calcium levels are high, but urinary calcium levels are low.
Conditions such as Osteoporosis and Paget's disease can be linked to disorders in calcium metabolism, as calcium loss through the urine can be high. Osteoporosis supplements can lead to hypercalciuria, increasing the risk of kidney stones or soft tissue calcification.

Patient Collection Note
24-hour urine collection:
- On the first day, on waking, eliminate the first urine in the toilet (note the date and time).
- For the next 24 hours, collect all the urine from the day and night, including that from the next morning when you get up at the same time.
- Recap and store the container between 2 and 8 degrees C. between each micturition.
- Note the date and time of the end of micturition on the bottle.
- Be sure to close the container securely for transport.
- Bring all the urine to the laboratory as soon as possible after collection.
