Inside red blood cells is packed hemoglobin and not much else.
The Complete Blood Count test measures the percentage of packed red blood cells in a whole blood sample.
Red blood cells are packed with a chemical compound called hemoglobin, which has the ability to both absorb and release oxygen molecules.
Red blood cells are considered cells, but they lack all organelles. Red blood cells cannot divide or replicate like other cells of the body. The blood's red color is due to the spectral properties of the hemic iron ion the hemoglobin. Each human red blood cell is packed with approximately 270 million hemoglobin biomolecules.

Packed red blood cells (PRBCs), also called "packed cells," are a preparation of red blood cells that are transfused to correct low blood levels. A unit of PRBCs begins as a 450 milliliter volume of whole blood. Platelets and plasma are removed to leave a preparation of 220 milliliters of mostly red blood cells. This step concentrates the red blood cells so that they occupy less space, thus the term "packed." One unit of PRBCs typically will raise the hematocrit by 3-4% and the blood hemoglobin concentration by 1 gm/dl. PRBCs last in refrigeration for up to 42 days, but under the right conditions, they can be frozen for up to a decade.

Typically when people refer to a blood bag they mean a transfusion of packed red blood cells. A transfusion of one unit of packed red blood cells would be approximately 250 mL.
