Learn hematology. Practice blood-cell identification. Connect what you see on a blood film with the science behind it. ViviCell brings real microscopy images, focused practice, lessons, and spaced review together for Medical Laboratory Science (MLS) and Medical Laboratory Technician (MLT) students. Study on iPhone or iPad, with all study content available offline. PRACTICE WITH REAL IMAGES Identify cells and selected cellular aberrations on authentic blood films. Choose your topics, session length, and starting difficulty. Answer choices adapt to each topic's recorded accuracy and confusions, while missed-image warm-ups help you revisit earlier mistakes. Compare images side by side in the Atlas. Use Practice Insights to see missed categories and repeated confusions, then open a focused practice session or the relevant reference. CONNECT MORPHOLOGY TO MECHANISM • 15 hematology and coagulation modules with diagrams and learning objectives • 300 quiz questions with answer explanations • 24 clinical cases with 69 questions linking laboratory findings to disease • Interactive RBC deformation lessons, including a two-cell splenic-slit comparison EXPLORE THE VISUAL ATLAS • Over 1,500 images • 27 cell categories and 27 RBC morphology cards • 56 cellular aberrations and 57 pathology conditions • Recognition features, common confusions, and source references Browse by lineage, finding, or pathology group. Zoom into images, compare look-alikes, or search across lessons, flashcards, quizzes, cases, and Atlas entries. Pathology entries are reference material; image practice covers cells and selected aberrations. RETURN TO WHAT YOU'VE LEARNED Add any of the 221 lesson flashcards to Review. Rate your recall with Again, Hard, Good, or Easy, and the app schedules the next review. Practiced cell and aberration images follow the same schedule. The How to study guide explains a flexible routine, recall grades, common difficulties, and the research behind the approach.
