Hi,
by minimum detectable signal, you probably mean the sensitivity. But that depends on the rest of your system. As far as I know, NF is usually enough for an LNA only. Of course if you want to specify sensitivity as limited by interference, you also need IIPn.
If you really want to know the sensitivity due to the LNA alone, its just the noise floor plus the NF plus the required SNR to meet BER specifications.
regards, Aaron
