1. Labratory Technologist.
2. Pathologist looks at blood and can tell what's in the blood, Not just blood but all cells and tissue. It's a good field to get into. The proper definition for a pathology is "The study of the characteristics, causes,and effects of diseases as observed in the structure and function of the body, Cellular pathology is the study of cellular changes in disease. Clinical pathology is the study of disease by the use of laboratory tests, and methods." Most pathologist work in autopsies. Hematology is another field that studies blood. and blood forming tissue. I think that would most likely fit into what you are looking for. Good luck.
