I emailed the buffalo office and they said my medical result has been received, but still in process.
If you are wondering whether it reached to Buffalo or not, you should email them. It only takes a day or two for them to reply to you.
I'm guessing they will be finalizing soon, and hopefully to receive my passport request by the end of Feb.
BTW, my E-CAS still shows as "we have started your application', not saying medical received or so.
