COMMON BLOOD TESTS

Introduction

Blood tests are laboratory tests which are done on blood to gain an appreciation of disease states and the function of organs. Given that blood flows throughout the body and it acts as a medium for providing oxygen and other nutrients, as well as, drawing waste products back to the excretory systems for disposal; blood tests are the most commonly performed medical tests.

Blood is useful as it is a relatively non-invasive way to obtain cells, and extracellular fluid (plasma), from the body to check on its health. Although the term blood test is used, most routine tests (except for most haematology) are done on plasma or serum.

Venipuncture is useful as it is a relatively non-invasive way to obtain cells and extracellular fluid (plasma) from the body for analysis.

If only a few drops of blood are needed, a fingerstick is performed instead of drawing blood from a vein.

Phlebotomists, laboratory practitioners and nurses are those charged with patient blood extraction. However, in special circumstances, and emergency situations, paramedics and physicians sometimes extract blood. Also, respiratory therapists are trained to extract arterial blood for arterial blood gases.
