Strange - both versions yield identical results on your post #1 sample file:
Code:
$ grep -E "GH=[0-9]+;|IJ=[0-9]+;|KL=[0-9]+$" file   - OR -
$ awk '/GH=[0-9]+;|IJ=[0-9]+;|KL=[0-9]+$/' file
Parameters are : GH=;IJ=789;KL=
Parameters are : GH=456;IJ=;KL=
Parameters are : GH=;IJ=789;KL=
Parameters are : GH=;IJ=;KL=23
Parameters are : GH=;IJ=;KL=23
Parameters are : GH=646;IJ=;KL=
Parameters are : GH=456;IJ=789;KL=2323

Just the line with all three fields empty is suppressed.

btw - PLEASE use code tags!

NOW I see - despite your first sample you are NOT using digits only in the fields.Try
Code:
grep -E 'BR=[[:alnum:]]+;|BRC=[[:alnum:]]+;|BRD=[[:alnum:]]+$' file
MI=a12345;MR=b1234;CI=b123;CI=1234;CN=45;A=49;TR=21;EC=130;ED=We again.;BR=1234;BRC=00;BRD=Good

and adapt other solutions if need be.
