@twitt1949 Hang in there, Terry. I know, this is a really rough period during a chemo cycle. When all the blood numbers get low, it seems to take morale right down along with it. Raising my hand in a ‘me too’ moment, I remember! It gets better! But takes some time. The goal is to rid the body of cancer cells.

You asked the difference between RBCs and Hemoglobin. RBCs (Red blood cells) are the cellular components of blood that are responsible for transporting oxygen. Hemoglobin is the iron-containing protein within red blood cells that binds oxygen for delivery to tissues. So, using an analogy, RBCs are the vehicles, and hemoglobin is the cargo that enables oxygen transport, if that makes sense. This is all with an un-caffeinated brain! 😅. The lower either of those two numbers go, the more sluggish you feel.
