Since you're referring to the 25 ohms or less on a ground rod then it would be up to the AHJ. Some may allow you to perform the test others may not. This is one reason why many of us simply install two ground rods and walk away.

We test numerous ground electrodes systems in this area, I have never been asked to test for a single electrode system to determine if a second electrode is required. But I think (from discussions with some inspectors) if you are on site with them you can test or if it is a letter they want 3rd party.
As noted drive the second rod and be done with it.

It requires either a clamp on ground resistance tester, or a 3 pole fall of potentail tester. For a single ground rod, you'd want the 3 pole tester.
Probably $800 and an hour to do the test.
