Waiting is Hard

I called the OB office around 4pm to see if they had the bloodwork results. They have a voicemail box set up just for asking about lab results. When I left my message I asked #1 if they had the results, #2 if they didn't when they thought they might be available, and #3 if someone could explain more about these antibodies because I've been rather worried. A nurse called back a few minutes later and said my file is on an OB's desk because the lab needed more information. I told her that the lab said that yesterday, but they figured it out this morning. I told her I had the blood drawn this morning. She said they'd call me as soon as they got the results. So I have no idea when that will be.
This afternoon when I was talking with my mom I said from what I had read I was figuring that the best case scenario was that the transfusion I received in January 2010 was of Kell positive blood. If that's where I got the antigens from, then most likely it means Paul is also Kell negative, which would mean our children would have to be Kell negative. If the baby I am carrying is Kell negative, the Anti-Kell antibodies in my bloodstream aren't going to hurt the baby. I wasn't 100% sure my analysis is correct (since I figured it out just by what I read online), but Jann (a friend who works in a Blood Bank) emailed me this evening and said the same thing. What a relief! The other scenario is that Paul is Kell positive, and then in that case I would have developed the antigen if Ian is Kell positive. Since I didn't have any Kell antigens in my pregnancy with Ian, I am assuming Nadia must be Kell negative, which means that Paul couldn't be homozygous. He'd have to be heterozygous in that scenario, which would mean there would be a 50% chance that the baby I'm carrying is Kell positive. So I'm praying that Paul is Kell negative and that I developed the antibodies from a Kell positive blood transfusion. That's definitely the best scenario at this point.

Jann also told me that the Rhogam shot doesn't have anything to do with the F or K antigens (which are the ones I have). That is a relief. She said if I had developed antibodies from the bleeding in January it would have showed up by now (and it didn't). So there was no harm done by my not having the Rhogam shot. What a relief! She also talked about the fact they can do an intrauterine transfusion or exchange the baby's blood with Kell negative blood. She didn't know as much about the F antigen. So now we wait for the titer results for both antibodies, and then most likely Paul will need to be tested in the near future so we'll have a better idea as to whether the baby I'm carrying is Kell positive or negative. I know there are still alot of unknowns, but I'm feeling more hopeful that I can deliver a healthy baby in September. I'll keep praying to that end, and hopefully by the end of the week the OB's office will call me with the titer results.
