Measurement of output noise from a transimpedance amplifier

I want to estimate the total noise(all sources) at the output terminal of a transimpedance amplifier (AD8009). Is it the input current noise times the transresistance or does one need to add the thermal noise ((4*Kb*T*R)^1/2) separately to get the total noise?
