I used to have -ve number with the UF and now, it seems that UF is increasing.
What is UF used to measure? What does it mean when the number is high (>1000)?
Yes, UF is ultrafiltration which is the amount of fluid that has been pulled off during dialysis. If you drink a lot, then you may want to pull off more. Did your training team go over this with you? They should have as it an important factor in your treatment.
