What is the cause of blood clots on the filter tube after dialysis?

Ask
Hello doctor. I went to dialysis because of chronic kidney failure grade 5. When the dialysis was finished, I saw that there were still many things like red clots on the filter tube. The doctor asked why such deposits appear? Please advise doctor, I would like to thank.

Hello!
You can understand simply The process of dialysis is as follows: Blood is taken out of the body and put through a system of wires and filters, removing harmful substances and then returning to the patient's body.
During this process, anticoagulant will be maintained continuously to ensure efficient blood flow in the lumen of the filter tube and the dialyzer.
Even so, there is still very little blood clotting in the lumen of the dialysis tube at the end of the dialysis as you describe.
This phenomenon will not affect you, so you can rest assured. Hope you get well soon!
