How is paternity of a child determined ruled out by blood type analysis?

In brief: There are some...

...Impossible outcomes: for example, an ab father cannot have a type o child, and vice versa.
If mother's type is known, more combinations become impossible: a+o or a+a cannot yield a b or ab; o+o can only yield o, etc.

The only way to determine the paternity beyond reasonable doubt is by doing DNA match

In brief: Rarely

There would have to be an impossible genetic match to rule out a child.
For example a male (type ab) cannot be the father of a type o child. However, usually this is not the case and other tests have to be used.
