McFarland turbidity standards are the most widely used method of inoculum standardization in clinical microbiology. These standards provide a standardized suspension of bacterial cells that is used to prepare inocula for antimicrobial susceptibility testing and other clinical microbiology assays. The turbidity of the McFarland standards is adjusted to a specific optical density (usually 0.5) to provide a consistent and accurate inoculum size.
