How the RDW SD Test Is Done :

When your doctor recommends a RDW SD test, you'll likely undergo a simple blood draw specifically targeting the measurement of RDW SD. A pathologist, a specialist in studying diseases, will collect a small blood sample from your veins using a needle. Your RDW SD test results will typically be available within a few hours after this procedure.
