Lab Act 2: WBC differential counts - Lab report patient B A Answer the folowing questions based on the differential WBC count slide show above. 1. Explain the difference between a WBC count and a differentialcount in terms of what information each provides. 2. Ona prepared blood smear slide, which of the 3 formed elements is present in greatest number? 3. How many different types of leukocytes are there? Patient 4. Which of the leukocytes are granulocytes? 5. Which of the leykoetvestypically has a polymorphic nucleus? 6. Which leukocyte typically has the largest size? 7. Which type of neutrophil is more mature, a seg or a band? 8. Which leukocyte typically is present in greatest number? 9. Which leukocyte typlcally hasa round nucleus. Transfer the data from your tally sheet to the Table below. Since you have tallied 100 leukocytes the numbers you have are percentages. Indicate whether the counts are high, lowor normal. Patient (high H, lowL or normal N) Normalcounts Neutrophils (50-70%) total (bands + segs) = % bands (normal< 10%) Lymphocytes (20-40%) total (typical+atypical) = % atypical = (should be none) Monocytes (3-8%) Eosinophils (1-4%) Basophils (0.5- 2%) C. Below are descriptions of the patients the class isevaluating. Determine which patient best correlates with your data. One patient has AIDS. Her lymphocyte count is low because HIVdestroys Helper Tlymphocytes. Her other WBCS percentages seem to be high, but that is only an illusion. Here is why. Pretend you have a fruit basket with five oranges and five apples. Each fruit is 50% of the total. Now take four apples out of the basket. The of oranges in the basket increases to 83% even though their number has not changed. In the same way, decreasing the number of lyvetxoGUes increases the percentage of neutrophis even though their percentage number has not changed. That is why the AI DS patient's elevated neutrophil percentage does not necessarily mean she hasa bacterial infection too. One patient hasanacute bacterialinfection. His neutrophilcount should show elevated numbers of new neutrophils (bands) rushing in to fight the infection. He also may show elevated total neutrophils One patient hasviral mononucleosis. Her lymphocyte count is high because more lymphocytes are rushing into her blood to fight this virus. Some lymphocytes may look atypical with jagged edges. Her spleen is swollen. She is a community college student. One patient has an acute parasitic infection with a worm called Trichinella because he ate undercooked bear meat.
