I took mine at TMC for the paranoma test. Basically they will just draw 4 tubes of blood from you and send for the down syndrome test
NIPT blood test For some cases where blood test is not accurate, doctor may suggest amniotic fluid (case where a twin baby, etc)
FTS(Oscar) - blood test and ultrasound. NIPT(Harmony) - blood test.
it's just blood test and ultrasound. good luck!
thanks for sharing
Stay strong!
