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.
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”.
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.
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.
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
About the Differential (Diff) section of your CBC: The Differential is the identification of the 5 different White blood cell types that are present in your blood, and in what amounts. This is usually completed by a highly sophisticated Hematology instrument.
Symptoms : weakness, depression, memory loss, unsteady gait and clumsiness (posterior and later columns degeneration) Diagnosed by B12 levels< 200 pg/ml. Methylmalonic acid and homocysteine elevated in early deficiency. Tx: oral B12 or B12 IM injections.
