Brief Answer:
No you dont have kidney disease

Detailed Answer:
Hello and welcome here,

It is a normal GFR and it suggests that CKD stage 3-5 is not there. So no kidney disease.

Potassium can also be considered normal as its near upper limit of normal range. Do you have any symptoms? Have you done an ECG?

One more thing as you said it suggest that CKG is not there so why they said like that “results rule out CKD 3-5”

In normal language of english it means that results tell us that she has stage 3 or 5 CKD isn’t am i right?

Brief Answer:
Diet has effect on potassium levels.

Detailed Answer:
Hi,

Common causes of hyperkalemia are kidney disease, potassium rich diet, some medicines, burns, injury to muscles, very high blood sugar levels.
In your case, potassium level is on higher side of normal range. So it is not to be worried unless you have symptoms or other medical conditions.
Diet has an effect on electrolyte levels including sodium, potassium etc. It is quite possible that potassium level is on higher side of normal range due to the bacon or other diet. Muscle injuries can also cause an increase. Did you get injured before the test?
"Rule out" in medical language means to take it out from the list of possible diagnosis. It also means exclude this diagnosis.
So no kidney disease

Okay but my eGFR and other creatinine things related to kidney came normal so what things or supplements should i take to lower down my potassium within the normal range ? I hope my kidneys are not damage if my other eGFR is normal. Just taking stress now because of reports.

Brief Answer:
Repeat the test

Detailed Answer:
Hi,

If you repeat the serum potassium level test, you will find a new value. If the repeat value is higher than normal, then you can go for an ECG of the heart as it may cause some rhythm disturbances.
Instead of taking something to lower its value, you may avoid foods that increase its value for few days like banana, non-veg.
Be assured that it is not worrisome. You can relax for now.
