As a B.Sc. there are very few jobs available in private companies. Maximum, you can go for Medical Laboratories. I will suggest you to go for M.SC. along with some normal job. That will be better as more jobs are available for M.Sc. post-graduates. Also you can go for exams like IIT JAM to get admission in IITs and IISc and after that you know that you will be having tons of opportunities.
