Solution

The severity of anemia is typically determined using a Complete Blood Count (CBC) test. Here are the steps:

  1. A healthcare provider will draw a small sample of blood, usually from a vein in the arm.
  2. The blood sample is sent to a laboratory.
  3. In the lab, the sample is analyzed to determine the number of red blood cells (RBCs) it contains. This is done using a machine that counts the different types of cells in the blood.
  4. The lab will also measure the amount of hemoglobin in the blood. Hemoglobin is the protein in red blood cells that carries oxygen.
  5. The results of these tests are used to calculate the hematocrit, which is the percentage of the blood that is made up of red blood cells.
  6. The results of the CBC, including the RBC count, hemoglobin level, and hematocrit, are used to determine the severity of the anemia. Lower than normal values indicate anemia. The lower the values, the more severe the anemia.
  7. The results are then sent back to the healthcare provider, who will interpret them and discuss the findings with the patient.
