Re: 18 years old with low eGFR
Those lab results are markedly different over a six month period. Whenever that occurs, I think it is reasonable to repeat them, and add anything related to it. I would ask to get a urinalysis done with microscopic exam, not just a dipstick, so someone can get a good count of any red blood cells, white cells and look for casts. If your urine is abnormal in any way, eg high protein, and the creatinine and eGFR come back similarly abnormal, I would see a kidney specialist. It is unlikely the UTI caused this, but it is important to be sure the infection is completely cleared up.
