Instead of solely looking at the WBC count, what must you consider when evaluating the hematologic status of a patient? - You must consider the individual absolute counts of each leukocyte type rather than the total WBC count. For such a critical evaluation, the first step is to order a CBC with differential. What are eosinophils? - Pro-inflammatory cells that are capable of either protecting or damaging the host depending on the situation. Their granules are toxic to parasites. What are r...

3 Uses of Platelet Counts - 1. Assess bleeding disorders 2. Part of coagulation workup 3. Monitor course of disease or bone marrow failure 4 Interfering Factors - 1. Abonormalities in RBC size (EX) Abnormally large (This is when the CBC M comes in handy) 2. Extreme elevated WBC elevation 3. Immediately after hemorrhage have not "caught up" so hematocrit will be normal (may decrease hours later) 4. Elevations & decreases same as for HGB 4 Red Blood Cell (RBC) characteristics - 1. Bicon...
