Spina bifida bloodwork test?

Did you get the spina bifida bloodwork test around 16 weeks? I have to call our insurance to see if they cover it, if not I am thinking we will wait until our 20 week anatomy scan to determine. What are the benefits from detecting it 4 weeks earlier since it’s a non curable birth defect? Just want to see what you fellow mamas have to say about it.
