You should be getting TBN and TAN on every analysis regardless. Without them, you have no clue if the change interval is correct for your particular motor and driving habits.
As others have said, an oil analysis can produce false positives. It can also make things look peachy when there are major problems. Even Blackstone will tell you that it is not a highly-accurate indicator of engine health.
