My dr. couldn't tell us the blood type of our dd either...not that he didn't want to, it's just that both times we had our dd's blood "typed", it came back "indeterminate". My dh is AB+, and I am O+....I didn't think it would be a big deal, but it kind of was. Our dd was SEVERLY jaundiced at birth, and got worse over the next few days (I could only hold her at feeding time, and then she had to go back under the lights, for the first 4 days

) The hospital said that sometimes when parents have the O/AB combinations, the babies are born jaundiced and have some of these issues. The nurse said it was not uncommon for blood typing tests to not work on these babies.

She said to wait a few months, and then have her typed again. What's really weird is the second test came back "indeterminate" as well. This last time, our dr said to just wait until she is older. He said even if you know your blood type, in case of emergency they always type it again anyway. We'd love to know her type, but I guess it is just not "meant to be". I figure we will just check everytime she has blood taken, but I am not going to draw blood just to know her type.
Of course, when she was teething, dh figured out that her blood couldn't be typed because she was actually a vampire!!! Glad those days are over!!
