What does high urine creatinine of 390.1mg/dl mean but everything else is normal ?

Proteinuria: You have proteinuria (p) and the first thing is to have a 24 hour urine collection to see the amount of protein in your urine and to assess your kidney function. Have a renal ultrasound to assess kidneys' size depending on the p, i would send off blood for aso, anca 2, complement c3 and c4, hiv, hepatitis b antibody to see if a cause could be found for the p, if not a kidney biopsy may be needed. ...Read more
