The results of the test mean the following: 1  a GFR of 60 or more is in the normal range. 2  a GFR of less than 60 may mean you have kidney disease. 3  a GFR of 15 or less is called kidney failure.
Family name is one that is shared with the family, but is not necessarily the surname. A good example to sum all this up would be the name of the main character of Kidnapped, David Balfour of the Shaws. His family name is the Shaws, but he is addressed as Mr. Balfour. His surname, in this case, is the same as his last name.
Where does my last name come from? Your last name is your surname. It is passed down through the generations to connect the members of a family. Surnames are a recent development in our history and their use started as a means to distinguish between people with the same first name.
