For the past few weeks I’ve been down to just once a week blood draws….last Monday my HCG was 20, and this Monday it was 21….which was a problem. My levels should be going down not staying the same, and definitely not going up. My RE scheduled another appointment with me this morning to discuss and do more testing.
He told me that sometimes in these cases your body can build up antibodies to the HCG and will show that you still have it in your blood stream even when you really don’t. He said the way they can test this would be to do another HCG….and split the sample into 2 vials. Test 1 sample regularly, and test the other by adding equal parts water to dilute the sample by 50%…..if I still had HCG in my system the levels today should have been 20 & 10, but if it was just the antibodies my levels would be 20 & 20. Sounds confusing right?? Well it sure confused me too.
Well today my levels were 16 & 16….meaning probably that I still had a little HCG in my system, but also my body probably had built up some antibodies. He said everything was okay, and I didn’t need to repeat my HCG again for another month…..so there you have it, 9 weeks post methotrexate for my ectopic pregnancy and I’m still not back to “baseline” yet.
