They do, in fact.

Yes, it does. In fact, it's almost the opposite: medicine recognizes inflammation as a common symptom (and intermediary contributor to lots of other conditions) with many causes and contributions, and the tests for inflammation don’t distinguish between causes, or even between the broad categories of chronic and acute inflammation, and therefore are only viewed as having particular marginal benefit in certain circumstances. OTOH, they are indicated when certain symptom clusters appear, or as part of a regime of monitoring inflammatory conditions.
