Do I need to get another Medical examination done for my field interview for AOS (I-485 application)? I already got one done in my home country.

I came to USA in december 2014 on K1 visa and before coming here I did all my medical and vaccinations done by US Embassy panel physicians and gave the sealed envelope regarding reports to immigration officer at Port of Entry in USA. After getting married in US I applied for Adjustment of status (I-485) application in January 2015 . Now I have interview for the I 485 case at regional field office and on I-797 C notice it says to bring Medical Examination Form ( I-693) if not already submitted. My question is do I need to do another Medical examination? I did not submit any I 693 Form with my AOS application since I already submitted medical reports sealed envelope at Port of Entry. Any help will be highly appreciated. Thanks!!
