Healthy term infants go through a physiological nadir of serum calcium levels at 7.5 - 8.5 mg/dL by day 2 of life. Hypocalcemia is a low blood calcium level. A total serum calcium of less than 8 mg/dL (2mmol/L) or ionized calcium less than 1.2 mmol/L in term neonates is defined as hypocalcemia. In preterm infants, it is defined as less than 7mg ...
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.
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 .
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.
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. [citation needed]
The total number of cations (positive ions) should be equal to the total number of anions (negative ions), so that the overall electrical charge is neutral. However, routine tests do not measure all types of ions. The anion gap is representative of how many ions are not accounted for by the lab measurements used in the calculation. These ...

As access to an ionized calcium is not always available a corrected calcium may be used instead. To calculate a corrected calcium in mmol/L one takes the total calcium in mmol/L and adds it to ((40 minus the serum albumin in g/L) multiplied by 0.02). [33] There is, however, controversy around the usefulness of corrected calcium as it may be no ...
