A biopsy is a procedure used for diagnosing rejection. The doctor will numb your skin with a local anesthetic and take a very small piece of the organ being biopsied using a needle. After the biopsy, a sandbag will be placed over the biopsy site for four hours to prevent bleeding. The biopsy results will be available in about 36 hours. 

If you are on any blood thinning agents such as, Aspirin, Plavix, Persantine or Coumadin, you need to call your coordinator to discuss a plan prior to being scheduled for a biopsy.
