My 13 week Blood test for Down syndrome came back as 1/280. Specialist said 1/300 is considered negative but someone my age/health should be much higher. Now my husband and I have to decide wether to take the next round of tests. The neck and nose measurements were good. I'm confident they're fine and we love them unconditionally. It'd just be nice to hear back from anyone who understands this situation. Have you heard similar news? What was your experience?
