Description
Estimated cost for Calcium-to-creatinine ratio test at general public hospitals in China is about ¥15-40, and at Grade 3A hospitals about ¥20-50, varying by hospital tier and region.
Main Uses
The main clinical uses of the calcium/creatinine ratio test are to evaluate the body's calcium metabolism, diagnose and monitor conditions related to abnormal calcium levels such as hyper- or hypocalcemia, and assess the risk of kidney stone formation. It is also useful in pediatric settings to monitor bone health and growth.
Normal Range
The normal range for the calcium/creatinine ratio in a random urine sample is typically between 0.12 to 0.20 (mmol/mmol). This can vary slightly based on the laboratory and the specific method used for measurement.
Low Values - Possible Causes
Possible causes of low values include: inadequate dietary calcium intake, malabsorption syndromes, hypoparathyroidism, and certain medications that decrease calcium absorption or increase its excretion.
High Values - Possible Causes
Possible causes of high values include: hyperparathyroidism, excessive dietary calcium or vitamin D intake, certain cancers (like multiple myeloma), and renal tubular acidosis.
