Hello aspirant
Among the courses, BSC microbiology, BSC not and MD pathology, you can do master's course only after completion of your degree course. you can pursue degree course in microbiology or mlt , after that doing MD is important. It's obvious that higher education has much more scope. MD pathologists are in higher demand now a days as you won't get license for laboratory unless you have MD pathologist or for opening laboratory you will have to hire a MD pathologist.
If a candidate having MD, gets more pay than BSC degree holder in any private hospitals ,government medical Institutes. So it's better to go for MD.
