Review Question - QID 214219

A 65-year-old man goes to the hospital to follow-up with his nephrologist. The patient has concerns about his new-onset fatigue and lack of appetite. Past medical history is significant for 20 years of type II diabetes and hypertension. Physical examination reveals bilateral 3+ pitting edema of the lower extremity. On urinalysis, output is below normal, and serum creatinine is 4.3 mg/dL. Furthermore, the patient’s glomerular filtration rate (GFR) is 14 mL/minute/1.73 m^2, and albumin excretion rate (AER) is 320 mg/day. One year ago, serum creatinine was 3.0 mg/dL, GFR was 32 mL/minute/1.73 m^2, and AER was 100 mg/day. Renal ultrasound now demonstrates the presence of shrunken kidneys. Given the disease progression, the nephrologist decides to start dialysis and discusses kidney transplant with the patient. What other lab findings would be expected in this patient?
