Kidney eGFR / Sickle cell

[t120]

After long suspecting i had kidney disease, blood test results show the 'all clear' for kindey/liver/urine. Which is strange as they don't seem like their working properly. If i so much as eat an egg, urine output extreases dramatically, breathing tightens and a breakout in light upper chest pain (Liver area) sets in.

And all this started when i started taking a protein supplement, which i stopped when symptoms came.

I also have Sickle cell disease, something that effects my red cells ability to transport oxygen around the body efficiently, possibly leaving certain organs that bit more vuneralble. And though i did wet the bet untill my mid teens (possible reduced renal?)i have had no major problems.

My question is this... Is it possible that i have partial kidney funtion that has been brought to the surface by me taking a protein supplement? My creatinine level is 69umol, what could this tell me about my eGFR and the level of my kidney funtion?

All feedback deeply appreciated.
