Final answer:
Blood cultures should use a culture medium that does not inhibit bacterial growth. Blood agar is one such medium that allows for the growth of many bacteria and facilitates differentiation based on hemolysis.
Step-by-step explanation:
Blood cultures are used to detect and identify bacteria in the bloodstream. To ensure accurate results and not inhibit bacterial growth, it is recommended to use a culture medium that supports the growth of a large number of bacteria and does not contain any substances that would hinder their growth. One example of such a medium is blood agar, which contains red blood cells to support bacterial growth and allows differentiation of bacteria based on hemolysis.
