Would a crp blood test indicate lymphoma? my doctor reassured me that i dont have lymphoma just allergies but shell do the test to reassure me.

CRP won't help: C-reactive protein (CRP) is elevated in any medical condition assoicated with inflammation. There are hundreds of medical conditions that could raise CRP. An elevated CRP level would almost never be from lymphoma; and a normal CRP would not mean you don't have it either. Don't press your doctor on what tests you need; trust her judgment.
