Any difference between SW & FW tests?

I was wondering if it's ok to use saltwater test kits in a freshwater tank? Will they give accurate readings?

Thanks!

if it say saltwater you can not if it says both you can.

Ok, let me be a bit more specific . Anybody know if the tests from an AP salt water master test kit will work on a freshwater tank? Obviously the PH test is for high range only and wont' work, but what about the others.

Hmm all the test kits I have from AP (ph, ammonia, nitrite) say they can be used for either FW or SW. The ammonia has 2 different color cards for FW and SW though.
