its made from blood
Blood agar is enriched because of the nutrients in it, including blood from various mammals, mainly sheep. Many types of bacteria can grow on blood agar. It is differential because organisms can be "differentiated" based on the type of hemolysis present on the agar as they grow. The blood cells in the agar are either completely lysed as the bacteria grows, which results in beta hemolysis, or a clear halo around the bacterial colony. If the blood cells are partially lysed, alpha hemolysis results and appears as a green halo around the colony. If no blood cells are lysed, this is called gamma hemolysis which is really no hemolysis at all. The colony will appear as just the colony with the blood agar unchanged. This is helpful in determining a preliminary identification of certain organisms such as Staphylococcus aureus, which is beta hemolytic and Streptococcus pneumoniae, which is alpha hemolytic. Differential agars help to differentiate bacterial species based on their metabolic processes as they grow. Hope this answer helped to clarify a bit more than the previous one!

Is a blood agar selective or differential?
Blood agar is a bacterial growth medium which contains 5% sheep's blood. It is considered to be differential but not selective, because it is an enriched medium that provides a rich nutrient environment for many types of bacteria, while a selective medium supports the growth of certain types of bacteria but inhibits other types. Blood agar is considered differential because it is used to distinguish pathogenic bacteria based on the effect of bacterial enzymes known as hemolysins which lyse red blood cells. Blood agar is mainly used clinically to detect the presence of Streptococcus pyogenes, the human pathogen which causes "strep throat". Blood agar can be made selective by the addition of other ingredients.
Is blood heart infusion agar a defined or a complex medium?
Blood agar is enriched medium which are complex media to which an extra nutrient source (such as blood in this case) is added to encourage the growth of fastidious heterotrophs.
