My blood type is o (positive), does that mean I can only recieve o (positive or negative) in case of an emergency?

O Positive: O + blood type means you have the rh antibody. If you receive o negative blood, which has no rh antibody, you are ok. If you receive o+ blood, you're ok.

Any transfusion is preceded by a cross match wherein the two bloods are checked for compatibility to lessen the risk of transfusion react. ...Read more

Blood test says my blood type is O Positive but on the part where is says Rh factor it says negative. How does that make sense? Mean something else?

Blood test says my blood type is O Positive but on the part where is says Rh factor it says negative. How does that make sense? Mean something else?

It doesn't: It doesn't really, but here's what probably happened: If you're pregnant and getting prenatal labs, in RH negative patients who've had a previous pregnancy it's typical to test for RH factor antibody (an immune response against RH+ blood). This test is not necessary in RH+ women, but it was likely done by routine, and the result, as expected in negative since an RH+ person won't have RH Antibody ...Read more

Android/gynoid: Android (methyltestosterone) body type refers to women whose waist/stomach is their largest body measurement; in contrast gynoid means a woman whose hips/buttocks are the largest measure. Android (methyltestosterone) bodies "work" fine, but there some concern that the fat location confers higher risks of metabolic and cardiovascular disease. Your blood type O+ has nothing at all to do with weight and will stay the same for life. ...Read more

My mom and dad both have o positive blood types why do I have a positive blood type?

My mom and dad both have o positive blood types why do I have a positive blood type?

Blood typing genetic: If you are the biologic child of 2 Blood Type O individuals, you cannot have Type A Blood. Tests are not perfect, however, and you could be misinformed. The test was the basis of the TV Series "Switched at Birth" in which a child tested in science class and her parents went to their doctor, retested, and found out she wasn't their child. This is unusual and rare. ...Read more

My blood type is o positive, and my husband is a negative. Will we have a+/- children, and would that make for high risk pregnancies?

Possible issue: I would not consider an a/o incompatibility issue high risk, but worthy of monitoring. In your lifetime you have likely been sensitized to the proteins on the a blood cells & your antibodies will cross into baby & boost his/her chances of having jaundice. Most do well without rx & some require some special monitoring & help. I can remember only 1 case in 3 decades that gave me any real trouble. ...Read more

Is it possible to have both parents with o positive bloodtype, but their child have o negative blood type?

Yes: The rh factor is inherited through separate genetic means from the blood type. The rh factor is a dominant gene, meaning only one gene is needed to cause expression of the factor. So two rh + parents can have a rh+/rh- gene pattern and have a 1/4 chance with every conception of having an rh-/rh- baby, 1/4 chance of rh+/rh+ baby and 1/2 of carrier rh+/rh-. ...Read more
