Diagnostic method. Blood serum < 2.1 mmol/L (corrected calcium or ionized calcium) [1][2][3] Treatment. Calcium supplements, vitamin D, magnesium sulfate. [1][2] Frequency. ~18% of people in hospital [4] Hypocalcemia is a medical condition characterized by low calcium levels in the blood serum. [5]
MDCalc is a free online medical reference for healthcare professionals that provides point-of-care clinical decision-support tools, including medical calculators, scoring systems, and algorithms. [1] MDCalc is also a mobile and web app. [ 2 ] The decision-support tools are based on published clinical research, [ 3 ] and MDCalc’s content is ...
The anion gap is a calculated measure. It is computed with a formula that uses the results of several individual lab tests, each of which measures the concentration of a specific anion or cation. The concentrations are expressed in units of milliequivalents / liter (mEq/L) or in millimoles/litre (mmol/L).
There is, however, controversy around the usefulness of corrected calcium as it may be no better than total calcium. [24] 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.
Calcium metabolism is the movement and regulation of calcium ions (Ca 2+) in (via the gut) and out (via the gut and kidneys) of the body, and between body compartments: the blood plasma, the extracellular and intracellular fluids, and bone. Bone acts as a calcium storage center for deposits and withdrawals as needed by the blood via continual ...
The urine concentrations of sodium, chlorine and potassium may be used to investigate conditions such as abnormal blood electrolyte levels, acute kidney injury, metabolic alkalosis and hypovolemia. [1][2][3] Other electrolytes that can be measured in urine are calcium, phosphorus and magnesium. [4] Target. Lower limit.
t. e. 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 amount of biologically active calcium varies with the level of serum albumin, a protein to which calcium is bound, and therefore levels of ionized calcium are better measures than a total calcium; however, one can correct a total calcium if the albumin level is known. A normal ionized calcium is 1.12-1.45 mmol/L (4.54-5.61 mg/dL).
