freshwater test kit work for saltwater?

[puffin]

I lent my saltwater test kit to a friend, and I need to test, I have a freshwater api test kit, will the freshwater nitrate test work on saltwater? I know that they sell the individual tests for both but what about the ones from the master test kit?
