About this app
HLA365 is a study companion for histocompatibility, transplant immunology, and immunogenetics certification exams — built for laboratory scientists and healthcare professionals working in histocompatibility, molecular diagnostics, serology, blood bank, and clinical pathology laboratories around the world. Whether you're preparing for ASHI's Certified Histocompatibility Specialist (CHS) exam in the United States, an EFI accreditation exam in Europe, or another national or international histocompatibility certifying body's exam, HLA365 covers the full blueprint.
CHS EXAM PREP
Work through 39 topics spanning the full CHS exam blueprint — from immunology fundamentals and HLA nomenclature through molecular typing methods (PCR, SSP, SSO, SBT, NGS), serology and crossmatch testing, antibody detection, cell processing, solid organ and stem cell transplantation, KIR genotyping, population genetics, and lab regulatory topics. Each topic includes a 15-question quiz with three levels of explanation for every answer — a quick simple summary, a detailed technical breakdown, and key recall points to reinforce the concept.
PRACTICE EXAMS
Take randomized, full-length practice exams drawn from a bank of over 1,000 questions pulled across every topic. After each exam, review every question you missed in one place, with full explanations, so you can immediately see what to study next.
REVIEW LIBRARY
Browse general and advanced review flashcards organized by category for quick refreshers between quiz sessions.
