Hi mama! Depende talaga kung saan ka magpagawa, pero last I checked sa mga hospitals around Metro Manila, around 1,500 to 3,500 pesos na ang OGTT, mas mahal kung private hospital, mas mura kung government facility like public health centers. A few of us pregnant moms nag-compare, at sobrang variable talaga depende sa location at facility, kaya best call mo na ang hospital mo directly para sa exact price, mas mabilis at accurate yun!
