What is the calcium (spot urine) lab test?
A calcium (spot urine) lab test measures the amount of calcium present in urine.
Why is the calcium (spot urine) lab test done?
A calcium (spot urine) lab test is done in order to:
- Diagnose kidney stones,
- Monitor kidney function,
- Diagnose disorders of the parathyroid gland,
- Evaluate whether your dietary intake of calcium is sufficient or not,
- Evaluate intestinal absorption of calcium,
- Diagnose conditions that result in loss of calcium from bones.
What does calcium (spot urine) lab test measure?
A calcium (spot urine) lab test measures the amount of calcium excreted in the urine. Calcium is a mineral that plays an important in the building and repairing of bones and teeth. Calcium also helps the nerves, muscles, and heart in functioning properly.
Are there any risks associated with this test?
There are no known risks associated with this test.
What are the causes of high calcium level in urine?
High levels of calcium in urine can be caused by a disease of the parathyroid gland, milk-alkali syndrome, sarcoidosis, renal tubular acidosis, vitamin D intoxication, use of certain medicines, and kidney failure.
What are the causes of low calcium level in urine?
Low calcium level in urine is caused by malabsorption disorders, vitamin D deficiency, hypoparathyroidism, and the use of thiazide diuretics.
Which food items cause high calcium level in urine?
Food items such as milk, cheese, egg, fish, green vegetables, and fruits raise calcium levels in urine.
Can too much calcium cause UTI?
Evidence suggests that excess calcium in the urine increases the potential for urinary tract infection.
INTERPRETATIONS
Normal Results
Results generally fall in these ranges:
- Children: 4.8 to 5.3 milligrams per deciliter (mg/dL) or 1.20 to 1.32 millimoles per liter (millimol/L)
- Adults: 4.8 to 5.6 mg/dL or 1.20 to 1.40 millimol/L (Normal value ranges may vary slightly among different laboratories. Talk to your provider about themeaning of your specific test results).
What Abnormal Results Mean
Higher-than-normal levels of calcium are may be due to:
? Decreased levels of calcium in the urine from an unknown cause
? Hyperparathyroidism
? Hyperthyroidism
? Multiple myeloma
? Thiazide diuretics
? Thrombocytosis (high platelet count)
? Tumors
? Vitamin A excess
? Vitamin D excess
Lower-than-normal levels may be due to:
? Hypoparathyroidism
? Malabsorption
? Osteomalacia
? Pancreatitis
? Renal failure
? Rickets
? Vitamin D deficiency
