Urine calcium

Urinary calcium refers to the determination of calcium concentration in urine for 24 hours. Calcium in the blood can be filtered out from the kidneys, and multiple multiples are absorbed into the blood, and excess calcium is excreted from the urine. Urinary calcium excretion is directly affected by blood calcium concentration, so changes in urinary calcium can reflect changes in blood calcium, but urinary calcium values ​​vary greatly. Calcium, protein intake and phosphorus excretion can affect calcium excretion, urinary phosphorus High urinary calcium is low. Basic Information Specialist classification: growth and development check classification: urine / kidney function test Applicable gender: whether men and women apply fasting: fasting Warm reminder: to ensure normal diet, normal activities, do not deliberately drink too much water, neither can stay in bed nor too vigorous exercise. Normal value Methyl thymol blue colorimetric method (MTB). Urinary calcium excretion varies greatly depending on the diet. (1) <3.75mmol/24h when low calcium diet; (2) <6.25mmol/24h in general calcium diet; (3) High calcium diet can reach <10mmol/24h. Clinical significance Reduced in hypocalcemia, hypoparathyroidism, vitamin D deficiency, nephrotic syndrome, acute pancreatitis, bone malignancy, hypothyroidism and so on. Increased in the sun exposed to excessive exposure, hypercalcemia, hyperparathyroidism, vitamin D poisoning, multiple myeloma, leukemia, malignant tumor bone metastasis, renal tubular acidosis. High results may be diseases: idiopathic urinary calcium, pediatric idiopathic urinary calcium, hypercalcemia, nephropathy, sputum poisoning precautions To ensure normal diet and normal activities on the day, do not deliberately drink too much water, neither staying in bed nor exercising too vigorously. Inspection process The urine of the subject was collected and detected by chemical methods. Not suitable for the crowd Generally not. Adverse reactions and risks No.
