Why does my eGFR fluctuate?

The estimated glomerular filtration rate (eGFR) is variable and it relies on a blood test, which may have day to day variations and it is an "estimation". Hence, the more times you do the test, the more accurate will be the estimate. It can depend on some food that you eat.

Can a GFR reading be wrong?

eGFR values derived from serum creatinine are frequently inaccurate when compared against GFR reference methods. The cause of this inaccuracy is likely related to non-functional factors, including unmeasured muscle mass and tubular secretion of creatinine. Accurate data are sparse.

Does GFR fluctuate with hydration?

Conclusions: In fasting adults, high hydration lowered GFR and increased natriuresis. After a meat meal, GFR increased only in the high hydration regimen and natriuresis only in the low hydration regimen. Hydration affects GFR and natriuresis under fasting conditions and after a meat meal.

Can dehydration cause low GFR?

Dehydration does cause the serum creatinine to rise and the estimated glomerular filtration rate (eGFR) will, accordingly, fall. The degree of change is generally proportional to the degree of dehydration. Severe dehydration can actually cause acute kidney injury and may lead to a need for dialysis therapy.

Can low GFR be temporary?

If the decrease in the estimated glomerular filtration rate (eGFR) is due to acute kidney injury with a sudden decrease in kidney function, this can commonly be reversed. If the kidney disease is due to chronic kidney disease (CKD), the recovery of eGFR is usually not possible.

What is the most accurate test for GFR?

Blood test to estimate your GFR (glomerular filtration rate). GFR is a measure of kidney function and can determine if you have kidney disease and what stage you're at. To find the GFR, healthcare professionals will test your blood for a waste product called creatinine. Creatinine comes from muscle tissue.
