If kidney function is functioning adequately after transplant, which statement best describes GFR value?

If kidney function is functioning adequately after transplant, which statement best describes GFR value?

• A. Adequate kidney function
• B. End-stage kidney disease
• C. Acute kidney injury
• D. Immunosuppression failure

Answer: (D)

GFR reflects how well the kidneys are filtering waste. When a transplanted kidney is functioning adequately, the GFR falls in the normal or expected range for the person’s size and age, showing effective filtration by the graft. Very low GFR indicates end-stage kidney disease, where filtration is severely impaired. A sudden drop in GFR points to acute kidney injury, a rapid loss of function. Immunosuppression failure is about the risk of rejection; if rejection occurred, the GFR would typically decline due to impaired graft function, not indicate an adequate function state. So the best description for a functioning graft is an adequate GFR.
