Final answer:
Automated differential systems count more cells than manual differentials by using advanced technology to analyze a larger number of cells in a shorter amount of time.
Step-by-step explanation:
Automated differential systems count more cells than we do with manual differentials. These systems use advanced technology to analyze a larger number of cells in a shorter amount of time. For example, flow cytometry can analyze thousands of cells per second, while a technician performing a manual differential may only count a few hundred cells in the same time frame.
