Blood test: estimated creatinine clearance test (low), what could it indicate? egfr & creatinine normal. potassium & sodium low. 28yr/f

How do you FEEL?: Many (maybe most) pathologists and nephrologists aren't impressed with the current practice of labs estimate GFR, creatinine clearance and so forth from a spot creatinine. Some formulas include race "because black people are more muscular than white people" -- these were never intended to be applied to individuals. Frankly, if your others labs are healthy, I'd ignore it.
