Probably not . .: First, please be assured that a Hb of 10.4 is not a danger to you or to the baby. The Bone Marrow makes 3 types of cells (WBC's, Platelets, RBC's). Your platelets and WBC's are normal. If you or your doctor were concerned about a bone marrow problem (i.e. bone marrow suppression), you can also get a test called a Reticulocyte Count. Best of luck!
