12. Kidney imaging reveals contraindications for undergoing biopsy or rilparencel injection
13. Maintained on any anticoagulant agents
14. History of anaphylactic or severe systemic reaction(s) to blood transfusions, Dextran 40, or bovine products, or contraindication(s) to above products due to medical reasons or participant preference.
