Calcipotriene causes a rapid rise in calcium ion levels. [31] Calcium ion levels can remain high for weeks if untreated and lead to an array of medical issues. [31] There are also cases of hypercalcemia reported due to dogs ingesting rodenticides containing a chemical similar to calcipotriene found in psoriasis cream. [31]
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.
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.
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.
Bone mineral is composed mainly of calcium, which functions in skeletal mineralization during growth. [4] Puppies younger than 5 months are not able to adjust the absorption of calcium in response to intake, therefore an oversupply or undersupply can be harmful. [10] When raised on diets deficient in calcium, pathological bone fractures can ...
Normal plasma levels vary between 1 and 2% over any given time. Approximately half of all ionized calcium circulates in its unbound form, with the other half being complexed with plasma proteins such as albumin, as well as anions including bicarbonate, citrate, phosphate, and sulfate.

Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
Normal parathyroid glands measure the ionized calcium (Ca 2+) concentration in the blood and secrete parathyroid hormone accordingly; if the ionized calcium rises above normal, the secretion of PTH is decreased, whereas when the Ca 2+ level falls, parathyroid hormone secretion is increased. [8]
