Introduction to Anemias Flashcards
2 general causes for anemia
- ↑ loss of RBCs (hemorrhage or hemolysis)
2. ↓ production of RBCs (in the BM)
7 general clinical symptoms of anemia
- Pallor
- Lightheadedness
- Muscle weakness
- Vertigo
- General lethargy
- Dsypnea (esp. exertional)
- Headache
Characteristics results in anemic patient
- Cell profile
↓ RBC and/or ↓ hemoglobin
Characteristics results in anemic patient
- RBC indices in M/H anemia
- RBC may be normal initially…but ↓ in stage 3
- ↓ H & H (Hb
Characteristics results in anemic patient
- RBC indices in macrocytic anemia
- ↑ MCV
Characteristics results in anemic patient
- RBC indices in N/N anemia
- Normal MCV
- Normal MCHC
Characteristics results in anemic patient
- Reticulocyte count in aplastic anemia
- ↓ to absent retic count
Characteristics results in anemic patient
- Reticulocyte count for extracorpuscular hemolytic anemia
↑ retic count
Characterstic RBC morphology
- Liver disease
Round macrocytes and target cells, stomatocytes, or spur cells
Characterstic RBC morphology
- Hereditary spherocytosis
Spherocytes
Condition characterized by structural variations in globin genes that result in the formation of abnormal globin chains
- Ex: sickle cell and Hb C
Hemoglobinopathy
Characterstic RBC morphology
- Pernicious anemia
??
Characterstic RBC morphology
- Sickle cell anemia
Sickle cells
Characterstic RBC morphology
- Thalassemia
- Target cells, schistocytes, spherocytes, teardrops
- H-J, B.S., Heinz (not on Wright stain)
- nRBCs!!!!
CBC profile
- Cold aggultinin
- ↓ RBC
- Normal Hb
- ↓ Hct
- ↑ MCV, WBC, RDW
- ↑ MCHC
