Hello, I am in the same position as you. Just did my FA scan on Monday and ARSA was detected in our baby. We did the FTS previously and it was low risk.
We hurriedly arranged for the amnio test to be done the following day as the results could take 2-3 weeks. We chose to go ahead with the amnio test because we wanted to be very sure, and hopefully ARSA is isolated and there are no other anomalies. Now all we can do is to keep our fingers crossed and hope for the best!
