I 485 name check

My I 485 case was transfered to local offce last october, and November 3th got fingerprint notice from local office. March 3 2005, got interview, but the officer told me that my name is checking, he could not issume my green card at that time, just leave my fingerprint for green card and photos, told me to wait at home for finanl green card. but now, name check is still not finish, do you think I have to do the second interview?
thanks,
