  2. Hypocalcemia - Wikipedia

    en.wikipedia.org/wiki/Hypocalcemia

    Hypocalcemia is a medical condition characterized by low calcium levels in the blood serum. [5] The normal range of blood calcium is typically between 2.1–2.6 mmol/L (8.8–10.7 mg/dL, 4.3–5.2 mEq/L), while levels less than 2.1 mmol/L are defined as hypocalcemic. [1] [3] [6] Mildly low levels that develop slowly often have no symptoms.

  3. Calcium metabolism - Wikipedia

    en.wikipedia.org/wiki/Calcium_metabolism

    Calcium regulation in the human body. [6]The plasma ionized calcium concentration is regulated within narrow limits (1.3–1.5 mmol/L). This is achieved by both the parafollicular cells of the thyroid gland, and the parathyroid glands constantly sensing (i.e. measuring) the concentration of calcium ions in the blood flowing through them.

  4. Hypercalcaemia - Wikipedia

    en.wikipedia.org/wiki/Hypercalcaemia

    Hypercalcemia, also spelled hypercalcaemia, is a high calcium (Ca 2+) level in the blood serum. [1] [3] The normal range for total calcium is 2.1–2.6 mmol/L (8.8–10.7 mg/dL, 4.3–5.2 mEq/L), with levels greater than 2.6 mmol/L defined as hypercalcemia. [1] [2] [4] Those with a mild increase that has developed slowly typically have no ...

    It is the first of its kind to directly measure levels of calcium and magnesium in blood — a much more reliable method of assessing nutrient status. This, the authors hope, might provide clearer ...

  6. Calcium in biology - Wikipedia

    en.wikipedia.org/wiki/Calcium_in_biology

    An abnormally high level of calcium in plasma is termed hypercalcemia and an abnormally low level is termed hypocalcemia, with "abnormal" generally referring to levels outside the reference range. Reference ranges for blood tests for calcium

  7. Disorders of calcium metabolism - Wikipedia

    en.wikipedia.org/wiki/Disorders_of_calcium...

    In a healthy physiology, extracellular calcium levels are maintained within a tight range through the actions of parathyroid hormone, vitamin D and the calcium sensing receptor. [1] Disorders in calcium metabolism can lead to hypocalcemia, decreased plasma levels of calcium or hypercalcemia, elevated plasma calcium levels.

  8. Milk-alkali syndrome - Wikipedia

    en.wikipedia.org/wiki/Milk-alkali_syndrome

    Milk-alkali syndrome (MAS), also referred to as calcium-alkali syndrome, is the third most common cause of elevated blood calcium levels (hypercalcemia). [ 2 ] [ 3 ] Milk-alkali syndrome is characterized by hypercalcemia, metabolic alkalosis , and acute kidney injury .

  9. Calcitonin - Wikipedia

    en.wikipedia.org/wiki/Calcitonin

    Calcitonin lowers blood calcium and phosphorus mainly through its inhibition of osteoclasts. Osteoblasts do not have calcitonin receptors and are therefore not directly affected by calcitonin levels. However, since bone resorption and bone formation are coupled processes, eventually calcitonin's inhibition of osteoclastic activity leads to ...
