  2. Hypocalcemia - Wikipedia

    en.wikipedia.org/wiki/Hypocalcemia

    Physiologically, blood calcium is tightly regulated within a narrow range for proper cellular processes. Calcium in the blood exists in three primary states: bound to proteins (mainly albumin), bound to anions such as phosphate and citrate, and as free (unbound) ionized calcium. Only the unbound ionized calcium is physiologically active. Normal ...

    Once calcium is confirmed to be elevated, a detailed history taken from the subject, including review of medications, any vitamin supplementations, herbal preparations, and previous calcium values. Chronic elevation of calcium with absent or mild symptoms often points to primary hyperparathyroidism or Familial hypocalciuric hypercalcemia. For ...

  6. 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.

  7. Disorders of calcium metabolism - Wikipedia

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

    Disorders of calcium metabolism occur when the body has too little or too much calcium. The serum level of calcium is closely regulated within a fairly limited range in the human body. In a healthy physiology, extracellular calcium levels are maintained within a tight range through the actions of parathyroid hormone , vitamin D and the calcium ...

    A basic metabolic panel including calcium is sometimes colloquially referred to as a "CHEM-8". Calcium, as an alkaline earth metal , is also an electrolyte, but abnormalities are more commonly associated with malnutrition, osteoporosis , or malignancy , especially of the thyroid .
