How the BUN Test Is Done :

When your doctor recommends a BUN test, you'll likely undergo a simple blood draw specifically to measure BUN levels. A pathologist, a specialist in disease study, will collect a small blood sample from your veins using a needle. Your BUN test results are typically available within a few hours after the procedure.
