A blood (serum) calcium test actually measures the calcium that is not in bones. For teenagers and young adults, it is normal to have calcium levels up into the mid to high 10's (in mg/dl). Calcium concentration is tightly controlled by Parathyroid Hormone (PTH) and 1, 25-dihydroxyvitamin D. Estimations of the serum levels of calcium are used in the diagnosis and treatment of parathyroid disorders, renal disease, a variety of bone disorders, carcinomas, acromegaly and pancreatitis. Sufficient levels of Alfacalcidol, vitamin D3 and magnesium can maintain calcium levels with a good diet without the need for calcium supplements. Gastrointestinal absorption of dietary calcium, renal excreti… The reference range may vary slightly between different labs, but a normal calcium blood level is around 8.6-10.2 milligrams (mg) of calcium per deciliter of blood (dL).

Males: 25-300 mg/24-hour specimen* Females: 20-275 mg/24-hour specimen* Hypercalciuria (high calcium in urine): >350 mg/24-hour specimen *These levels are reflective of individuals with average, unrestricted calcium intake, which is 600-800 mg/day. Normal urine calcium levels.

If your calcium levels are not normal, it doesn't necessarily mean you have a medical condition needing treatment. Some other causes of hypocalcaemia include: Decreased vitamin D concentration Normal vitamin D levels in the blood are 20 ng/ml or above for adults. You might need treatment if your calcium level goes above or below these levels. Normal Calcium Levels: What is a high calcium level? Normal calcium levels in a healthy adult should fall between the range of 8.8 – 10.5 in mg/dL and 2.25 - 2.625 in mmol/L.

Since the body loses calcium every day, it should be included in the diet. The UK Biobank study was used to assess the association of genetic predisposition to increased serum calcium with estimated bone mineral density derived from heel ultrasound in 426 824 individuals who had, on average, calcium levels in the normal range. Other factors, such as diet, supplements, and certain medicines, including antacids, can affect your urine calcium levels. Calcium is the most abundant mineral in the human body, and it is essential for the proper function of virtually every cell.

The assays are run throughout the day and night.The in-lab turnaround time is normally less than 24 hours.The test can be ordered as an urgent request. Ranges of serum calcium concentration are used to classify the severity of hypercalcaemia: Mild hypercalcaemia is an adjusted serum calcium concentration of 2.6–3.00 mmol/L. Hyperphosphataemia, when levels of phosphate in the blood are above the normal range, can be caused by kidney disease, parathyroid issues, and metabolic or respiratory acidosis.
