No word yet on what tests still need to be done ... but Mike's family ain't waiting around -- we're told they're holding a memorial without Mike's body this Sunday in Seattle for friends and family ... to give them a chance to pay their respects early.
Once Mike's body is back in the family's possession, sources tell us, they plan to hold TWO funeral services -- one for fans, and one for family.
As we previously reported, Mike died suddenly last week in a Salt Lake City home -- after mixing methadone and anxiety pills.
