Red blood cells (RBCs) are the oxygen-carrying cells in circulation in the body. RBCs contain the molecule hemoglobin that can bind oxygen (O2) and transport it all over the body. Anemia is lack of sufficient RBCs (and hemoglobin) to carry enough O2. You get tired easily, have muscle weakness, and your heart struggles. Your bone marrow will produce more RBCs that need more hemoglobin to fill them. Hemoglobin has iron in the center that binds to the O2. So you need RBC production from the bone marrow and iron intake from the diet to produce more O2-carrying capacity. This causes your RBC count, the number of RBCs in circulation per unit volume, to increase. RBC count is called the Red Cell Count (RCC). RCC in cells/femtoliter = hematocrit divided by mean corpuscular volume in femtoliters per cell.
hemoglobin fool!
hematocrit
RBCs are made up of hemoglobin, therefore if the hematocrit is high you should expect a high hemoglobin determination.

Hematocrit & Hemoglobin
11.7 -15.5
Typically between 30% and 40%.
Hematocrit and hemoglobin content of blood measure are not the same thing. The hematocrit, also known as the HCT, is the percentage of RBC in the blood volume. Hemoglobin, on the other hand, also known as HGB, is the measurement of protein in the blood.
If you have a low blood pressure, low hematocrit and hemoglobin, you need to have a blood transfusion.
