Also known as: CD34 analysis
Different types of blood cells (specifically white blood cells) can be identified by the proteins on their surface. Those proteins are called antigens. CD34 is an antigen on the surface of a very early blood cell that is important in the formation of the bone marrow. Physicians often check the number of CD34 cells when they try to assess the ability of the bone marrow to recover, or when they collect those cells for Stem Cell Transplant CD34+ cell number can also be tested on a bone marrow sample.
The CD34 test requires a basic blood draw. This is typically taken from the arm after the phlebotomist (person who takes the blood) cleans and disinfects the area. Then the blood sample is taken to a laboratory for further testing and analysis.
No special preparation is needed for this test. What are the risk factors? Bleeding, bruising, infection and pain are mild side effects or risk factors of the CD34 test.
