What is the context: Depends on what you are looking for. No simple test. There are specific tests for certain things (penicillin).

Mild rash is listed as side effect in benzonanate. I had very mild rash, but how to know if this IS side effect or allergy to the drug?
No test avail: Can't diagnose specifically in this forum, but, in general, I've prescribed benzonatate since it came out and haven't seen anyone experience rash from it. Must be pretty rare.
