- Previous year questions on Blood Components and Transfusion Reactions for NEET PG (National Eligibility cum Entrance Test - Postgraduate), from the Pathology section of the exam.
- Most questions here come from previous-year papers of Indian postgraduate medical entrance and licensing exams; where a paper and year are recorded the question carries them. The image-based questions are original vignettes written around an openly licensed figure, and were never asked in any exam.
