    • Enlarged liver
    • Abnormal heart and lung sounds
    • Enlarged neck veins from increased pressure

    • Creatinine
    • Creatinine clearance
    • Urinalysis
    • Urine appearance and color

    • ANA titer (lupus)
    • ANCA (antineutrophil cytoplasmic antibody for vasculitis)
    • Anti-glomerular basement membrane antibody
