Bacteria (routine): The yield of blood cultures in adults is volume-dependent and increases approximately 3% per mL of blood cultured; 20% of bacteremic adults have less than 1 colony-forming unit in 10 mL of blood. About 80% of patients who have positive blood cultures are positive on the first sampling, 90% are detected with two samplings. Last updated on June 4th, 2021.
