Blood Agar Base, Improved is used with blood for the isolation and cultivation of a wide variety of fastidious microorganisms in a laboratory setting. Blood Agar Base, Improved is not intended for use in the diagnosis of disease or other conditions in humans.
Blood agar bases are typically supplemented with 5 – 10% sheep, rabbit, or horse blood for use in isolating, cultivating, and determining hemolytic reactions of fastidious pathogenic microorganisms. Without enrichment, blood agar bases can be used as general purpose media.
In 1919, Brown experimented with blood agar formulations for the effects of colony formation and hemolysis. In Blood Agar Base, Improved, the formula was modified slightly to enhance organism growth and neutralize any toxic metabolites.
