Blood Chemistry

I was following the instructions on the "Blood Clotting to the Rescue: How to Stop Too Much Blood from Flowing" science project, and the results were the opposite of what science states. The size of the "blood" balls grew as I added more sodium citrate. Every science website that I have looked at says that sodium citrate is an anticoagulant. An anticoagulant is a substance that prevents or reduces coagulation of blood, prolonging the clotting time. That would mean that as I added more sodium citrate, the size of the "blood" balls would decrease not increase. Do you know why this would happen? Thank you for your help!
