Hemolytic Anemia Flashcards
CBC – Usually N/N anemia, reticulocytosis
Blood - Target cells, sickle cells, NRBC’s, Howell-Jolly bodies, Pappenheimer bodies
Lab - Sickledex screening test (turbid)
90% HbS, 8% HbF, 2% HbA2, 0% HbA
HbF protective-inc with hydroxyurea
Sickle Cell Disease
CBC - usually normal
Blood – few targets, no sickles
Lab – Sickledex screening test +
52% HbA, 45% HbS, 2% HbA2, 1% HbF
Sickle Cell Trait
CBC - Usually N/N anemia, reticulocytosis
Blood – Targets, Hb C crystals
Lab – 95% HbC, 2% HbA2, 3% HbF, 0% HbA
Hemoglobin C Disease
CBC - Usually normal
Blood – Targets
Lab – 60% HbA, 37% Hb C, 2% HbA2, 1% HbF
Hemoglobin C Trait
CBC - Usually N/N
Blood – Targets, HbC crystals, sickles, hybrids
Lab – Sickledex screening test +
HBC = HbS, 2% HbF, 1% HbA2, 0% HbA
Hemoglobin SC Disease
CBC - M/H anemia MVC 50-70, nl to high RBC count
Blood – Targets, stippling
Lab – 93% HbA, 5% HbA2, 2% HbF
Minor Beta Thalassemia
CBC - M/H anemia, MCV 50-60
Blood – Targets, NRBCs, stippling, anisopoikilocytosis
Intermedia Beta Thalassemia
CBC - Marked M/H anemia
