Hi,
I will guide in best possible way,
Kidney transplant is done when
creatinine level are very high,for eg some what near 10,
Actually
creatine 2 is not that high it means kidney
That is transplanted is working,
Though correlating with earlier investigation is neseceray,
Other thing is to check urine output,
It should be more than before in general sense,
Fever may occur because immunosuppresents are given to prevent rejection,
Hope this information helps,
Seeing your sr.creatinine ,urea reports
Nephrologist will give you the best expert opinion,
Wish you a good health.
