How to Look for Antibodies in Your Blood

We can also count the number of red blood cells and white blood cells you have. We can really look for almost anything in your blood. It's kind of amazing you can be kind of like detectives too right? If something is bothering me and I'm not feeling well you might be able to figure out by looking at my blood what is it that's bothering me? What's making me sick? Maybe partly through those antibodies because the body is making these defenses against certain diseases.
