Blood tests are laboratory tests done on blood to gain an appreciation of disease states and the function of organs.
Since blood flows throughout the body, acting as a medium for providing oxygen and other nutrients, and drawing waste products back to the excretory systems for disposal, the state of the bloodstream affects, or is affected by, many medical conditions.
