In Jun2021, the patient had episodes of severe vomiting, crazy numbers of Glomerular Filtration Rate (GFR), blood urea (BUN) and creatinine: GFR was down to 13% in which 90 is normal (this is indicative of a kidney transplant), her BUN is high, and creatinine was 3.6 which was 3 times the normal, the other day and goes really high; her magnesium was low.
