    Remember, tests are done to determine the cause of your symptoms or disorder. Since the blood goes around the body, it can carry traces of the illness you have wherever it is, brain, hands, feet, anywhere within your body. Next time a doctor explain the results of your blood test, don’t be shy to ask for explanations, indications and what does those names and numbers mean
