Acute rejection usually occurs within the first 6 months after transplant surgery. During that time, we will regularly draw blood from your child to monitor the level of creatinine, a protein released into the blood as waste from the muscles. Higher levels of creatinine in your child’s blood may mean the kidney is not doing a good job flushing waste out of your child’s body.
We confirm that this is what is happening by performing a biopsy – it is a procedure where we insert a needle into your child’s kidney and take a tiny sample of tissue. Looking at the tissue under a microscope, we will be able to see if your child’s immune system is causing injury to the kidney. Your child will be asleep for this procedure and might need to stay in the hospital overnight afterwards.
It is common to see at least 1 rejection episode about 2 to 3 months after surgery. Do not get discouraged. This is why we check your child so closely with lab work and other tests.
