Professional CD34 Test

Different types of blood cells (specifically white blood cells) can be identified by its proteins on the surface, known as antigens. CD34 is an antigen on the surface of a very early blood cell crucial for the formation of the bone marrow. Regenerative Medical Physicians often check the number of CD34 cells when they are  assessing the ability of the bone marrow to recover, or when they collect cells for Stem Cell Transplant.
