I don't know too much about this, but due to some other symptoms I've had, I get this test panel if I m/c again. My doc says that a positive for one of these blood clotting tests means heparin (blood thinner) during subsequent pregnancies. This, of course, makes the pregnancy a bit more high risk, but from what I've read lots of women are very successful on heparin.
I'm so sorry for your loss!

I hope you'll hang out here for awhile....the ladies here are very supportive.
