Doctor's answer:
For Down syndrome screening, you don't need to fast or do any special preparation. Just go to the hospital on time for the check-up. However, if you need to get other tests done at the same time, such as diabetes screening or liver and kidney function tests, you will need to fast. It's recommended to ask the doctor clearly what tests will be performed.
