Blood isn't best: What is best to diagnose would be a sputum culture and respiratory viral panel if you wanted to isolate the causative agent. A good physical exam and history should be able take care of you in most situations though and help to make sure you don't have pneumonia. Bacteria in the blood is a sign of a more serious infection.
