The Prenatal Decision Tree can be used as a step by step guide through the proper course of prenatal care for alloimmunized patients according to current medical literature. This chart can be used for any antibody which may cause HDFN (anti-D, anti-K, anti-E, anti-c, anti-Dia, etc). If your care plan differs from this, discuss it with your physicians and seek a second opinion if needed. For additional references and a more in-depth explanation of the information in this tree, please see our Providers page. When you click submit, there will be an option to download a PDF copy of your tree for your records. You may print, save, or discard this copy. This interactive tool is based on a flow chart provided by Dr. Kenneth Moise. To view the complete chart, click the image below.
