Study Notes
Red Blood Cell Indices
- Red cell distribution width (RDW) measures the variability of the size of red blood cells.
Diagnostic Tests
- Hemoglobin electrophoresis is the gold standard test for thalassemia and sickle cell anemia.
Iron Deficiency Anemia
- Total iron-binding capacity (TIBC) measures the body's ability to bind to iron.
Anemia Diagnosis
- The most sensitive test for iron deficiency anemia (IDA) is the serum ferritin level.
Red Blood Cell Characteristics
- The normal range for Mean Corpuscular Volume (MCV) is 80-100 femtoliters.
- Poikilocytosis is a condition characterized by the presence of abnormally shaped red blood cells.
Anemia in Males
- The typical hemoglobin level range for males is 13.5-17.5 grams per deciliter.
Nail Abnormalities
- Koilonychia, characterized by spooning of the fingernails, is a condition often associated with iron deficiency anemia.
Eating Disorders
- Pica and pagophagia refer to cravings for abnormal substances, such as ice, dirt, or starch, often seen in iron deficiency anemia.
Microcytic Anemias
- Thalassemia and iron deficiency anemia are categorized as microcytic anemias.
Red Blood Cell Size Variability
- RDW (red cell distribution width) measures the variability in size of red blood cells.
