What is high creatinine level after a kidney transplant?

No precise answer: The creatinine test is a surrogate for the more precise measurement of kidney function called gfr--glomerular filtration rate. The creatinine can vary based on donor and recipient gender, age and size, as well as some medical conditions most recipients with very good kidney function have a GFR between 40-70 cc/min and a serum creatinine between 1-2 mg/dl.
