Can a chiari malformation type one be picked up in an amniocentesis test?

No: Chiari malformation is associated with many conditions, some of which have abnormal chromosomes that would show up by amniocentesis. The malformation itself can be seen by fetal ultrasound but not usually at 16-18 weeks when visualization of fetal anomalies might prompt recommendation for amniocentesis.
