In a CBC or complete blood cell count they measure 3 kinds of blood cells red blood cells, white blood cells and platelets.
you have to count the amount of platilets and blood cells and white blood cells and T-cells
Due to hemoglobin in the blood.
The complete blood count (CBC) is one of the most commonly ordered blood tests. The complete blood count is the calculation of the cellular (formed elements) of blood. These calculations are generally determined by special machines that analyze the different components of blood in less than a minute. A major portion of the complete blood count is the measure of the concentration of white blood cells, red blood cells, and platelets in the blood.
A complete blood count (CBC) typically includes measurements of red blood cells, white blood cells, and platelets. Specific components measured in a CBC include hemoglobin, hematocrit, white blood cell count, platelet count, and differential white blood cell count which includes bands. Bands are immature white blood cells, and an elevated band count may indicate an infection or inflammation in the body.

The formula to calculate red blood cells is: Total Red Blood Cells (RBC) = Red blood cell count (RBC count) in millions per microliter (mcL) x Volume of blood in milliliters (mL).
A reticulocyte count is a blood test that can measure how fast red blood cells are made by the bone marrow and released into the blood. It is given as a percentage of red blood cells that are reticulocytes.
Reticulocytes are immature red blood cells. The reticulocyte count is most useful if you have anemia (low red blood cell count). A low reticulocyte count means your body is not making enough red blood cells in the first place. There may be a problem with your bone marrow. A high reticulocyte count means you are losing your red blood cells after you make them, maybe because of bleeding or red blood cells that break down too quickly.
A white blood cell (WBC) count determines the concentration of white blood cells in the patient's blood. A differential determines the percentage of each of the five types of mature white blood cells.
A white blood count measures the total number of white blood cells in the body. White blood cells are an essential part of the immune system and help to fight infections and foreign invaders. Abnormal levels of white blood cells can indicate various medical conditions.
A reticulocyte count is a blood test performed to assess the body's production of immature red blood cells (reticulocytes).
