1/40 chance neural tube defects

Alycia
Just got a call from my midwife and she said the blood results came back from my sequential screening and I'm ok for Down syndrome but the neural tube defects (spins bifida etc) came back 1/40, I have my gender ultrasound next Monday the 29 but she wants to get me in sooner with the specialist so he can do the ultrasound to check the spinal chord etc.. Anyone have these results and it was ok, or not??
