After my blood test at my last doctors appointment, I was informed that my anti E levels were above the tolerable level. So what did this mean for me and the baby? It meant that we'd be meeting with a Perinatologist for a specialized ultrasound for a closer look at what was going on.
Here is my watered down explanation. Besides certain blood types, there are several protein types associated with our blood. My E protein type is ee (or recess) and my husband's is Ee (heterozygous). We each pass one on to our offspring. During the course of my baby bearing years and blood trafficking between me and my babies, I was introduced to the big E. My body recognized it as foreign (since it wasn't a little e) and started producing antibodies against it.
My first two pregnancies, no problem. But now with baby #3, my body is producing higher level of antibodies that are fighting against the baby. Luckily the E protein mismatch isn't nearly as severe as others. So we will continue to have weekly ultrasounds to monitor the blood flow and velocity in the baby's brain. If the levels stay within the tolerable curve, I carry the baby to term and no problem. If the levels rise considerably, the anti E has been destroying too many of the red blood cells and the baby runs the risk of being anemic. In which case, the baby can be given a blood transfusion.
So for now, it's a bit of a waiting game. Dr. Belfort was awesome about answering our questions and quelling our concern. Although I am now labeled with a "high risk pregnancy," we feel blessed with the prognosis.
