Hematology
Hematology Consults
Practical frameworks for common inpatient and outpatient hematology questions encountered during internal medicine residency.
Anemia
Approach anemia using the hemoglobin trend, MCV, reticulocyte response, peripheral smear, iron studies, hemolysis testing, nutritional evaluation, kidney function, inflammation, and marrow assessment.
Read guideThrombocytopenia
Confirm the count, recognize urgent syndromes, calculate the 4Ts and PLASMIC scores, evaluate ITP, and apply current platelet-transfusion thresholds.
Read guideHemolysis
Confirm red-cell destruction, calculate the corrected reticulocyte response, interpret smear findings and the DAT, distinguish immune from nonimmune causes, and recognize urgent transfusion problems.
Read guidePancytopenia
Distinguish impaired marrow production from destruction or sequestration, identify smear emergencies, evaluate reversible causes, calculate the HScore, and determine when marrow biopsy is needed.
Read guideCoagulation Abnormalities
Interpret prolonged PT and aPTT, exclude anticoagulant interference, understand mixing studies, recognize acquired factor inhibitors, and evaluate disseminated intravascular coagulation.
Read guideTransfusion Reactions
Respond to suspected reactions, distinguish hemolysis, allergy, anaphylaxis, sepsis, TACO and TRALI, complete the blood-bank workup, and recognize important delayed complications.
