How does calcium ion concentration in blood affect muscle contraction? Calcium dissociates from troponin C or calmodulin as the cytosolic calcium concentration decreases as a consequence, which terminates the contraction process. The main pathways promoting muscle relaxation involve the second messengers cAMP and cyclic guanosine monophosphate (cGMP).
Why is calcium corrected with albumin? The physiological basis for the albumin adjustment is the theory that when albumin is reduced, the amount of calcium bound to albumin is also reduced, such that the total serum calcium may be low despite a normal ionized calcium concentration.
Do you need to correct calcium for normal albumin? Therefore, to correct for an albumin level of less than 4 g/dL, one should add 0.8 to the measured value of calcium for each 1-g/dL decrease in albumin. Without this correction, an abnormally high serum calcium level may appear to be normal.
Why is calcium low with low albumin? There are several conditions in which the serum calcium level may be a poor reflection of ionized calcium. One common situation is hypoalbuminemia. Since a significant portion of calcium circulates bound to albumin, low serum albumin levels may result in a low serum total calcium despite normal ionized calcium levels.
