Blood tests help us to better understand your body and the issues that might affect your health. A blood test involves drawing blood, usually via a hypodermic needle inserted into a vein in the arm, and sending the sample for testing. Taking a blood sample is usually painless and over in a matter of seconds. For more information visit: http://bit.ly/1RNwl8H
