Train hematology reasoning one case at a time.

Case-based learning for medical students, residents, internists, dentists, and practitioners who want sharper CBC, smear, anemia, bleeding, thrombosis, and malignancy reasoning without pretending the app is bedside automation.

Free core: Optional support keeps the project open.

Current release Production beta with 128 pathway-ready cases, case-specific Clinic Decision Lab pathways, selected management reasoning steps, verified smear quiz mapping, local progress, saved review, and PWA install support. Built from synthetic, de-identified teaching patterns only. No patient identifiers, source wording, or patient-specific advice.

Smear quiz mode Image first. Teaching after answer.

Quiz image A

Case prompt Platelet count 42 x 10^9/L, no bleeding, analyzer flags clumps. What is the safest interpretation step?

After answer Teach the morphology branch, not just the label.

The practical source emphasizes that platelet clumps can make the analyzer count falsely low; the learner should protect the patient from an artifact diagnosis.

Learning tracks

Start narrow, then mix cases until the pattern sticks.

Teaching blueprint

Built around decision quality, not recall alone.

Start from a clinical trigger

Acute anemia, bleeding, leukocytosis, transfusion reaction, or smear abnormality.

Force a lab interpretation step

CBC, PBS, reticulocyte response, coagulation test, hemolysis marker, or morphology clue.

Separate look-alikes

IDA vs thalassemia, leukemoid vs leukemia, rouleaux vs autoagglutination, TMA vs ITP.

Close with a safety point

Recognize red flags, escalate emergencies, and explain the principle without patient-specific advice.

Editorial stance

Built as education, not bedside automation.

Cases teach reasoning patterns and cite the medical basis behind the answer.
No patient identifiers should be submitted to the platform.
Drug doses, calculators, and patient-specific treatment advice are out of scope for the first release.
Diagnostic morphology uses real owned or properly licensed images whenever it matters.
Patient-log material is converted only into aggregate themes and synthetic cases.

Support open hematology education

Keep the core learning resource free.

If BloodRounds helps your study, teaching, or clinical reasoning practice, optional support can fund hosting, licensed teaching images, platform maintenance, and new evidence-checked cases.

Support options are being prepared. No popup. No guilt wall. Core cases stay open. Contact / collaborate
