Both are normal glomerular filtration rates and reflect your relative hydration. Yes, this number can fluctuate quite a bit from day to day depending on your fluid intake and other factors.

eGFR can vary on a daily basis and variation is greater when eGFR is higher than 90. Your eGFR is normal. Wish you good health!
