Do all negative blood types automatically have a negative Rh factor? (if you neg on one are u neg on other)

Do all negative blood types automatically have a negative Rh factor? (if you neg on one are u neg on other)

It's the same thing: In the abo/rh blood typing categories, if the rh factor is not there, it is called a negative blood type. (in other situations, when doctors are not talking about the abo/rh typing, then "negative" would mean that something else is missing. For example, a test for sickle cell anemia would be called "negative" if no sickle cell mutation was found, but would not be talking about the rh factor.). ...Read more

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
