I have Lupus Nephritis since 2008. My renal function was down to 17% but then started to come up as I lost 60lbs and my blood pressure has come way down to 111/68 on a consistent basis. 2 weeks ago I had my labs done and all my tests came out normal except my creatinine which went from 1.6 to 2.8 within 3 months. I m puzzled at how this can happen. I m on a kidney friendly diet. I need to know possible causes for just this 1 test result to be so out of whack when it was so low a few months ago, and what I can do to lower this number.
Hi, welcome to Chat Doctor. Lupus nephritis require kidney biopsy to determine class of the disease, its treatment and prognosis. Creatinine can usually go high in lupus nephritis if there is flare of lupus. Do urine routine report, urine protein quantification, DS DNA, c3 and sonography. Then consult your nephrologist, or you can get back to me with above reports. You should be on immunosuppressant if there is lupus flare. I think this would be helpful to you. Best wishes. TC.
