LEARNING OBJECTIVES. Define “CBC”. Define and explain red cell indices including derived values such as MCV, MCHC and MCH. Define and explain erythrocyte sedimentation rate. Describe the main cell types observed in peripheral blood. Describe what is meant by the term “differential count”.
8 Ιουν 2024 · The standard CBC includes a measured red cell count (RBC), hemoglobin (Hb), and hematocrit (Hct), calculated red cell indices, a platelet count, and a white cell count (WBC). Most analyzers now also automatically generate a leucocyte differential.
Your healthcare team can order a CBC with or without a differential. A differential gives a more detailed view of your white blood cells. There are five types of white blood cells present in the blood; neutrophils, lymphocytes, monocytes, basophils, and eosinophils. Each cell type performs a different function.
examining the CBC are Hgb (as a general indicator of anemia or polycythemia), MCV (a key parameter for the classification of anemias), RBC distribution width (a rela-tively useful parameter in the differential diagnosis of ane-mia), RBC count (an increased RBC count associated with anemia is characteristic in the thalassemia trait), platelet
CBC – Part 1 The hemogram. CBC – Part 2 WBC differential & blood morphology. CBC – Part 3 RBC morphology & platelet estimate. CBC – Part 4 Post-test. The review of hematopoiesis and blood cell morphology (i.e., Hematology Atlas located on the LSUHSC server) is recommended as a prerequisite for the CBC exercise.
MCHC and RDW. MCHC = mean corpuscular hemoglobin concentration Hb/HCT = 32- 36 gm/dl. RDW = red cell distribution width It is correlates with the degree of anisocytosis or variation in red blood cell width. Normal range from 10-15%.
complete blood count includes 5 major parts. Each time you have a CBC, you’ll find numbers for each part in your results. Keep in mind that normal ranges may be slightly different for men and women. The 5 parts of a CBC are: White blood cell (WBC) count.
