How to determine if a UVM_REG is initialized

Is there a way to determine if a uvm_reg has been initialized?

For example, a register that is located in EDAC protected block ram will power-up uninitialized. If the register is read before it is written to (or before the DUT has updated it internally) an error will occur.

I would like a way to tell if the register has been initialized in order to predict this error case.
