Definition. Hypocalcemia, a low bood calcium level, occurs when the concentration of free calcium ions in the blood falls below 4.0 mg/dL (dL = one tenth of a liter). The normal concentration of free calcium ions in the blood serum is 4.0-6.0 mg/dL.
Renal tubular disease, including acquired proximal renal tubular acidosis due to nephrotoxins (eg, heavy metals, cadmium in particular) and distal renal tubular acidosis, can cause severe hypocalcemia due to abnormal renal loss of calcium and decreased renal conversion of vitamin D to active 1,25(OH) 2 D.
