Hi sachin,
Everyone is born with a certain blood type that is either Rh positive or Rh negative. Rh-positive blood is more common than Rh-negative blood. About 85% of Caucasians are Rh positive, while the percentage is even higher for African-Americans, Asians, and American Indians.
Blood group O individuals do not have either A or B antigens on the surface of their RBCs, but their blood serum contains IgM antibodies against both A and B antigens. Therefore, a group O individual can only receive blood from a group O individual, but they can donate blood to individuals of any ABO blood group (ie A, B, O or AB).

If both of you and your wife are Rh positive, there is no reason to worry about Rh incompatibility. However, if your wife is Rh negative, then most likely your baby will inherit your blood type, creating incompatibility between your wife's blood and the foetus. Though that's a high risk pregnancy, there is a cure available for that too.
So go ahead and request them to get her blood test done to determine the group and also to find if she is perfectly healthy.
thanks!
take care!
