I totally understand the anxiety, the waiting period can feel really long. From what I've heard from friends, KKH usually takes around 1 to 2 weeks for NIPT results, though it can sometimes stretch a bit longer depending on how busy they are. Your intermediate risk result doesn't necessarily mean anything is wrong, so try not to stress too much in the meantime. If you haven't already, do give KKH a call to ask for a specific timeline, they should be able to give you a clearer picture based on when your sample was sent.
to update on this, I heard back from kkh 5 working days later, and all is clear! hope this is helpful
