Hello,
Do you have any past medical history including hypertension or diabetes?
Do you have any protein in your urine?
If you are of black African descent, did your doctor multiple your eGFR result by 1.2?
I would most definitely not worry about a single reading of eGFR. Even if it is accurate, if you have no other medical problems, and no significant protein in your urine, provided blood pressure remains well-controlled, then you have an excellent outlook and dialysis would not be in the cards. But if I had more information, I could give you a better answer.
