What does TNCs stand for? Why might we refer to WBCs as this when performing a hemacytometer count?

Expert Solution
Step 1: What is hemocytometer?

The hemocytometer is a microscopic slide with tiny squares of known size on it. To count cells we put a small amount of the fluid on the slide. Then, we look at the slide under a microscope and count how many cells are in each square. Finally, we add up all the cells we counted to find the total number in the sample.
