Does Pregnancy actually affect serum calcium and inorganic phosphate levels?

Abstract

The serum level of calcium and inorganic phosphate in pregnancy is less well defined among Black Nigerians, than among Caucasians. This case control study assessed the relation of serum calcium and inorganic phosphate concentrations to pregnancy in Nigerian women. Blood samples were collected by venepuncture technique from 128 pregnant women during their first, second and third trimesters. A total of 72 non pregnant women were recruited as controls. Serum calcium and inorganic phosphate levels were determined. Pregnant women had significantly lower serum levels of calcium and inorganic phosphate compared to controls (P
