Assignment:
What is the equation/formula used to calculate the manual WBC count? Please write out the equation.
What is the manual WBC count if you counted an average of 19 WBCs per square and 8 squares were counted at a 1:20 dilution?
You just completed a manual WBC count and the total WBC for the patient is 12.8 x 109/L. You are now performing a manual differential on this patient. Your count is as follows:
- Neutrophils: 58
- Lymphocytes: 34
- Monocytes: 5
- Eosinophils: 2
- Basophils: 1
- nRBCs: 8
What is the absolute neutrophil count? (please show your work)
What is the absolute lymphocyte count? (please show your work)
What is the equation used to calculate the corrected total WBC count for the presence of ↑ nRBCs?
Please calculate the corrected WBC count with the given total WBC result and nRBCs counted in the manual differential. (Please show your work
What is the equation/formula used to calculate the manual RBC count? Please write out the equation.
What is the manual total RBC count if you were to count 506 RBCs in the area you just circled on the hemocytometer grid and the dilution used was 1:200? (please show your work)
What is the equation/formula used to calculate the manual platelet count? Please write out the equation.
What is the manual total platelet count if you were to count 307 platelets in the area you just circled on the hemocytometer grid and the dilution used was 1:100? (please show your work)
You are performing a reticulocyte count on an adult male patient that has been diagnosed with anemia. His Hgb is 7.9 g/dL and HCT is 23.9%.
You counted 38 retics out of 1,000 RBCs - what is the % retic? (please show your work)
Since the patient's HCT is so low, a corrected retic count is needed. Please write out the equation used to calculate a corrected retic count.
Now, calculate the corrected retic count using the equation you just provided with the provided patient results above. (please show your work)
Now, imagine you counted 500 RBCs instead of the typical 1000 RBCs for the retic count, and you counted 22 retics - what is the retic count in this scenario? (please show your work)
