As a pathologist/ doctor, how do you assess my condition from a blood report?

See below. We evaluate all the numerical counts for abnormality. Different conditions are characterized by too many or not enough cells in the blood . It also helps in combination to look at the blood smear under a microscope to look for abnormal cells.
Appropriate tests! Blood tests are chosen to look at specific things, and simple tests can yield powerful information. Many tests can be chosen from, and relate to your physical exam, medical history, and your physician's judgement about what may be going on with an illness or "condition." x-rays and scans are additional tests that show other things, all of which take years to learn in medical school.
