I’ve googled it, looked similar to NT scan but the difference is the method to detect Down syndrome. NT scan is via ultrasound but NIPT is thru blood test. I went for NT scan today at 13w5d but too late cuz sono said my baby’s size is now at 14w2d, i guess the date KK’s gv to me was inaccurate. So the sono said advisable to do at 12w eventhough NT scan can be done at 11w-13w6d. You can opt for NT scan also if you’re at 12w 😇
