Doctor's answer:
For amniocentesis, fasting and holding urine are generally not required, but it's best to ask the doctor when undergoing the test. This is because it may not be just a simple check of a physiological sign; if other tests are included, fasting might be necessary. The fasting period is usually around 10 hours.
