Imagine you want to know how much iron, HGC or cholesterol you have in your blood, what does people look at? I try to search on internet and fail to find. I naively imagined it would be with a microscope but also… it feels weird and would ask to like… count manually?
Just wondering how they do…

I’m pretty sure all of the listed blood tests are done using different analytical methods (different ways to prepare the sample before finally running it on an instrument). I am pretty sure they don’t use a microscope for most blood tests. They use chemistry to prepare the blood sample, which then gets analyzed by an instrument to produce a quantitative result.
Below is a link to a pdf of the procedure for iron analysis.
