The following results are obtained from a patient: RBC -4.63 X 10 12 /L Hg - 15 g/dl Hct-0.40 L/L (40%) 1. Using the "Rule of Three" for Hb/Hct, what would be the expected value for the hemoglobin? 2. What could cause this hg to be falsely elevated? 3. What would you do to correct for the above interferences? From another patient, the following results are obtained: Hgb - 3.2 X 10 12/L Hg - 5.8 g/dl Hct - 0.189 L/L (18.9 %) 1. Calculate the RBC indices. 2. How would you describe the RBCs consistent with these indices? 3. How should you verify this?

Exercise #3: Calculate the RBC concentration of this blood sample (in cells/ΑΙ). Show your work. Remember that these five small squares account for 1/5th of the area of the central 1.0 mm grid. Exercise #4: Using the information you have learned throughout this assignment, diagnose your patient. For WBCs and RBCs: (a) state if the cell concentration is above or below normal and (b) list which possible conditions may be indicated by the results.

Calculation of Mean Corpuscular Volume (MCV) and Mean Corpuscular Hemoglobin Concentration (MCHC) Calculate the MCV and MCHC using the formulas below and the values given on p. 8.6. Show your work. If your hematocrit is 45.72, plug the number 45.72 into the MCV formula: MCV = (Hematocrit x 10) / RBC count (in millions/mm³) If your RBC count is 5 x 10⁶, plug in the number 5 x 10⁶ into the MCHC formula: MCHC = Hemoglobin concentration (g/100mL blood) / Hematocrit
