Understanding Your Results
Results post to your secure online account usually in 1β2 business days. A higher CRP points to more inflammation but doesn't identify the cause on its own β it's best interpreted alongside your symptoms and other tests. If your goal is heart-disease risk, the high-sensitivity hs-CRP is the better choice.
