Complete Blood Count Interpretations

These flashcards cover essential vocabulary regarding Complete Blood Count (CBC), including definitions and conditions related to blood parameters.

Complete Blood Count (CBC)

An important investigation focusing on Red Blood Cells, White Blood Cells, and Platelets to screen for disorders.

Anemia

Known as low RBC count, it can result from bleeding, destruction of RBCs, or deficiencies in nutrition.

Polycythemia

Known as high RBC count, it may be due to dehydration, pulmonary disease, or increased erythropoietin.

Hemoglobin (Hb)

The protein molecule in red blood cells that carries oxygen, with normal values varying by sex.

Hematocrit (Hct)

Percentage of blood volume occupied by red blood cells; normal values differ for males and females.

Mean Corpuscular Volume (MCV)

Measures the average size of RBCs; low values indicate microcytic and high values indicate macrocytic anemia.

Mean Corpuscular Hemoglobin (MCH)

Measures the average mass of hemoglobin in a single RBC.

Mean Corpuscular Hemoglobin Concentration (MCHC)

Measures the average concentration of hemoglobin in RBCs, reported as a percentage.

Reticulocyte Count

Indicators of bone marrow production of RBCs, low counts suggest production issues while high counts suggest peripheral causes.

Leukopenia

A low white blood cell count, often seen with viral infections or as a result of chemotherapy and other conditions.

Leukocytosis

An increase in white blood cells, often due to infection, inflammation, or stress.

Thrombocytopenia

Low platelet count that can result from immune disorders, cirrhosis, or certain medications.

Thrombocytosis

High platelet count associated with chronic inflammation, malignancy, or post-splenectomy.

Eosinophilia

An increase in eosinophils often linked to allergies, asthmatic conditions, or parasitic infections.

Monocytosis

An increase in monocyte count indicating chronic infections or myelodysplastic disorders.

Basophilia

An increase in basophils often associated with allergic reactions or certain leukemias.

Platelet Distribution Width (PDW)

Measurement of variation in platelet sizes, indicating potential underlying conditions affecting platelets.
