Calcium levels are regulated by the parathyroid glands.

The first is a shift in the relationship between calcemia and PTH secretion to higher serum calcium levels, indicating a decrease in the sensitivity of PTH secretion to calcemia.

In most cases, total calcium is a good substitute for free calcium since the free and bound forms are usually each about half of the total.

The direct measurement of ionized calcium is particularly important during surgery as well in severely ill patients, when changes in total calcium do not reliably tell how abnormal the ionized calcium level is.

Always perform a malarial screen on these patients.

Usually, intestinal absorption of dietary calcium only affects calcium levels temporarily and is not involved in the short-term regulation of serum calcium.

The level of calcium in the blood (calcaemia) must remain constant.

Usually, intestinal absorption of dietary calcium only affects calcium levels temporarily and is not involved in the short-term regulation of serum calcium.

Any symptomatic patient whose calcemia exceeds 3.25 mmol / L requires urgent treatment.

CA (calcium) – deviations can indicate a variety of diseases.

Thus, in a subject whose albumin is measured at 20 g / L, the measured calcium concentration can be increased from 0.4 to 0.5 mmol / L in order to obtain a “corrected” calcemia.This procedure provides a fairly approximate result.
