9. Phlebotomy
Phlebotomy is the technical medical term for drawing blood from the body to perform tests. This can be very useful for medical professionals because our blood can tell us a lot about our overall health. One thing that is often checked is the red blood cells themselves.
Red blood cells are often checked for the structure of the cells individually, and how many of them are flowing through the blood. Blood tests can also reveal the presence of pathogens in the blood stream and can also reveal the presence of cancers. Such tests are often used when more information is needed to be able to reach a conclusive diagnosis.
