Question

How did the process of a CBC (complete blood count) change with the invention of the automatic cell counter?
Cell counts were done using a microscope instead of a machine.
Cell counts were done more slowly but more accurately.
Cell counts were done for white blood cells instead of red blood cells.
Cell counts were done more quickly and were more reliable.

Answer 1

Cell counts were done more quickly and were more reliable.

Automatic cell counters speed up counting, process many more cells, reduce human error and variability, and improve accuracy and reproducibility compared with manual microscopy.
