How the RDW Test Is Done :

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