Normal results. The amount of calcium in the urine of someone eating a normal diet is 100 to 300 milligrams per day (mg/day). A diet that’s low in calcium results …
Understanding the Results. If you follow a good diet and you have no health problems affecting your calcium levels, a normal test result would be 100 to 300 mg/day of calcium in your urine. If your diet is low in calcium, your result may be 50 to 150 mg/day of calcium in your urine.
Calcium levels of 250 to 300 mg in a 24-hour sample, or 6.2 to 7.5 millimoles per day are said to be high calcium levels in urine. As mentioned, the diagnosis of the condition and the cause is very important, since the treatment varies accordingly. The result of high calcium in urine is very often kidney stones.
Hypocalcemia (Low Level of Calcium in the Blood) Calcium is one of the body’s electrolytes, which are minerals that carry an electric charge when dissolved in body fluids such as blood (but most of the body’s calcium is uncharged). Although most of the body’s calcium is …
Foods rich in calcium are dairy products (milk, cheese), eggs, fish, green vegetables, and fruit. Most people who have low or high levels of calcium do not have any symptoms. Calcium levels need to be very high or low to cause symptoms. High calcium levels in the urine can cause kidney stones.
When blood calcium levels are low, the parathyroid gland releases parathyroid hormones (PTH). PTH stimulate cells in the bones to break bone down and release calcium into the blood. A total calcium blood test will show how many milligrams of calcium are in a deciliter of your blood.
I have read a number of people with elevated 24-hr urine calcium but don’t recall reading about anyone with a low reading. I just had this test done during past month and was advised to take more calcium. My level was 93, and the optimal recommended level is 100-300.
Excessive calcium loss in the urine can be due to factors like high intake of salt, caffeine, soda, or sugar, low levels of nutrients like magnesium, vitamin D, and vitamin K, and even prolonged stress. These factors all promote an acidic pH (which promotes calcium loss), and they’re all things you can begin correcting on your own.
If you are eating a diet low in calcium, the amount of calcium in the urine will be 50 to 150 mg/day or 1.25 to 3.75 mmol/24 hours. Normal value ranges may vary slightly among different laboratories. Talk to your provider about the meaning of your specific test results.
