I am a 53 yr old female caucasian, I just had a metabolic panel done, Creatinine was .98 BUN at 20, and the stated GFR was estimated at 66 using the CKD-EPI . I read in an article that I am within the normal limits but according to DaVita calculator I am in Stage 2 CKD? I also read though that if you have taken corticosteroids, which I did about 2.5 weeks ago, (7day Prednisolone) it may skew the result.
