Read full description

Prepare for the ASCP MLS exam with 1,650 original practice questions for medical laboratory scientist certification. Build a medical laboratory exam prep routine with practice questions, lab images, full answer rationales, and focused study modes for the areas that need more attention. Every question includes an explanation plus rationales for its answer choices or matches. Review why a response fits and why the alternatives do not, then return to missed questions for another attempt. Build reasoning across laboratory concepts instead of memorizing an answer key. VISUAL PRACTICE FOR THE LAB Build recognition skills with 200 image-based questions from the app's microscopy and laboratory image collection. Practice blood cell morphology, Gram and acid-fast stains, parasites, urine crystals and casts, and other visual findings used throughout medical laboratory study. ASCP MLS EXAM PREP 2026 — STUDY BY TOPIC For a flexible MLS exam preparation routine, choose a subject area and follow a three-step flow: • Skim concise study notes for key ideas. • Review swipeable flashcards for active recall. • Answer topic questions and read the full rationale after grading. The app also includes Smart Review with spaced repetition, weak-area practice, shuffled practice, and a missed-question review notebook. Use these modes to bring difficult material back into view and decide what to study next. TIMED MLS PRACTICE TEST Run a 100-question mock exam with a 150-minute timer. Questions are selected across the seven subject areas using the app's configured weighting. Review the results and use the subject breakdown as a study signal. Practice scores are for self-assessment only. They are not official ASCP BOC scaled scores, do not predict an exam result, and do not replace the current examination content guideline. SEVEN MEDICAL LABORATORY SUBJECT AREAS Practice across: • Blood Banking • Chemistry • Hematology • Microbiology • Immunology • Urinalysis & Body Fluids • Laboratory Operations Use the readiness view to compare your practice activity across subjects. Set an exam date, follow the daily study plan, check your streak, and return to lower-confidence areas when planning the next session. CORE STUDY CONTENT AVAILABLE OFFLINE Questions, flashcards, notes, and images are bundled with the app, so core study sessions can continue without a connection after installation. Internet access is required for purchases, restoration, store services, and downloading any available content update. START WITH A FREE PREVIEW Try preview questions and a topic in each subject area. Some study features require Premium. Check the in-app purchase screen for the current options available through your store account. INDEPENDENT STUDY AID This app is independently published for exam preparation and educational use. It is not affiliated with, endorsed by, sponsored by, or otherwise associated with the ASCP Board of Certification (ASCP BOC) or any other certifying or licensing body. ASCP, ASCP BOC, BOC, MLS, and related names and marks belong to their respective owners and are used only to identify the examination this app helps users study for.
