###Human: Is it necessary to get Down's syndrome test done if there is no fetal movement? ###Assistant: Hi. During the late first trimester, nuchal translucency test by ultrasound and double marker test (BhCG, PAPP-A) are done to rule out 80 % cases of Down's, Edward, Patau syndrome. These are normal screening methods, generally covered in Medicare. If you are screened positive and been suggested for some confirmatory test, I am afraid, you need to spend out of pocket. Secondly, fetal movements can be felt only as early as 15 weeks, so be patient regarding that part.
