6. On an adult male patient, you make a 1:200 dilution. You count RBCs in 5 small squares inside the center square with the following results: Side 1: 55, 57, 47, 53, 51 Side 2: 49, 51, 48, 53, 46 a. What is the dilution factor? b. What is the area counted? c. What is the volume counted? d. Are these counts acceptable to average? e. If acceptable to average, what is the cell count per microliter? f. Interpret the cell count (Normal, abnormal increased, abnormal decreased)

Give the relative abundance of the nine different cells( as mentioned below) in one cubic centimeter of blood sample.   a. The human erythrocytes b. Granulocytes 1. neutrophil 2. eosinophil 3. basophils c.agranulocytes 1. Lymphocytes 2. Monocytes 3 platelets 4. Frog erythrocytes 5. Frog thrombocytes

For another patient, the following results are obtained: RBC count = 3.20 x 1012/L HGB = 5.8 g/dL. HCT = 18.9% (0.19 L/L) 1. Calculate the red blood cell indices. 2. How would you describe the red blood cell volume and hemoglobin concentration based on these indices? 3. How should you verify this?

A laboratory result showed a Hb= 13.5gm/dl, RBC = 4.5 × 10 power 12L, WBC = 3.5 × 10 power 9/L, serum iron is low and RDW-CV = 15%. High Neutrophils & Eosinophils but low lymphocytes. a. Calculate the MCV b. Calculate the MCH c. Calculate the MCH d. Base on your MCV & MCH comment and what type of anaemia is present. e. What is the pricise type of anaemia present. f. Give three characteristics of anaemia present in (d) g. Interpret the RDW-CV h. Interpret the high N & E and low lymphocytes. I. What is the reference range for platelets.

Answer the following questions after looking at lab data:  Calculate MCV. MCH, MCHC   Indicate which results are abnormal, stating if they are low, high, or potentially critical   Predict what kind of anemia the patient might have based on their interpretations.       Data Set 1:  Data Set 2:    RBC: 2.36 x 1012/L                             RBC: 1.96 x1012/L   WBC: 6.73 x 109/L                             WBC: 8.74 x 109/L   Hgb: 7.3 g/dL Hgb: 5.1 g/dL   Hct: 21.9% Hct: 15.2%   Plt: 263 x 109/L                               Plt: 337 x 109/L   RDW: 14.5% RDW: 15.7%

1. Identify which among the evacuated tubes can be used for a complete blood count test. Explain 2. Identify which among the evacuated tubes can be used for Prothrombin Time. Explain

Which of the following statements are true of the life cycle of RBCs (Read carefully and select all of the correct statements)? Please watch the Haematology-Red Blood Cell Life Cycle video A. erythropoesis is the process of the RBC from stem cell to eythrocyte. B. reticulocyte does not become a eythrocyte. OC. RBC removal happens in the spleen, liver and the bone marrow D. The spleen has mainly macrophages that engulf the old erythrocytes and break them down. E. Old RBCs are phagocytized by lymphocytes in the spleen, and RBM. OF. Bilirubin is normally eliminated by the kidneys. G.Iron and protein in the diet are necessary to become part of hemoglobin. H. Bilirubin is a waste product of the heme of old hemoglobin. Type here to search W % 5 O E B 00 8 A H W
