A member asked:
Can drinking lots and lots of water before blood tests falsely lower creatinine and falsely increase egfr and increase rbc count?

It will not increase RBC count, may lower it; and it will not materially lower creatinine and thus not affect eGFR. Why would you want to overhydrate. It is good to be hydrated, but do not try to over do it. Wish you good health!

In euvolemic hyponatremia, is water drawn out of blood into the cells? Would this make your rbc, hemoglobin and hematocrit become elevated even though you drink plenty of water?
I drink plenty of fluids and do not take any diuretic medication. My rbc, hemoglobin, hematocrit and creatinine are consistently high. My blood sodium is consistently low normal. What conditions can cause chronic hypovolemia?
How much water should I drink before blood draw? My bloodwork is always perfect except for BUN/Creatinine ratio. Just a tick over normal every time. Dr says because of dehydration. I try to drink 16 oz prior. Not enough??
