OVM- Using interface to access DUT signals

Hi

 I am working under OVM based testbench and i would like to use status signals from the DUT in the data item - req (to make sure it is not in error state ).

What is the way to do it?

I would like to avoid using response since this is the current implementation and it seems that it can be done much more simple.

 Is it possible to use the tansaction interface or any other interface connecting the driver to the design?

Thanks
