No, you cannot directly pursue an MD Pathologist diploma after completing a B.Sc. MLS (Medical Laboratory Science).

There isn't a separate MD Pathologist diploma program. MD (Doctor of Medicine) is a postgraduate degree program in Pathology, whereas diplomas are typically short-term vocational courses.

The eligibility criteria for MD Pathology programs in India require an MBBS (Bachelor of Medicine and Bachelor of Surgery) degree. MBBS is a primary medical degree that qualifies you to practice medicine. B.Sc. MLS, while focusing on medical laboratory science, doesn't provide the necessary foundation for advanced medical practice like pathology.

Consider pursuing an M.Sc. (Master of Science) degree in Pathology. This program would provide you with a deeper understanding of pathology concepts and might qualify you for some research or lab-based roles in pathology departments. However, it wouldn't qualify you to become a practicing pathologist.

If your interest lies in research aspects of pathology, you could pursue a Ph.D. in a related field like Clinical Laboratory Science or Molecular Pathology. This path would require strong research skills and potentially some additional coursework to bridge the gap between your B.Sc. MLS and the Ph.D. program.

I hope it helps!
