NephX is a secure messaging platform built exclusively for the nephrology community in India. WHY NEPHX EXISTS Every brilliant case discussion, every academic insight that happens in WhatsApp threads — most of it disappears. NephX exists to preserve the collective wisdom of Indian nephrology, structured and searchable for the next consultant, the next fellow, the next decade. WHAT'S INSIDE - Case discussions with structured threads and searchable archives - Voice and video calls — one-tap, with colleagues anywhere in India - Academic meetings — host journal clubs, CME, board meetings (recorded + transcribed) - Status updates — quick clinical posts visible for 24 hours - Document and DICOM sharing — radiology, lab reports, scans - Live location for emergency consults - End-to-end encrypted transit, encrypted at rest VERIFIED DOCTORS ONLY NephX is free, but access is gated by manual verification. Our admin team verifies medical credentials against Medical Council registries before activating each account. Patient confidentiality is a first-class design constraint, not an afterthought. NOT A MEDICAL DEVICE NephX is for peer academic discussion only. It is not a medical device, not a diagnostic tool, and not intended for direct patient care. BUILT BY THE NEPHX TEAM Developed by GeeApps for the Indian nephrology community. Free forever for verified members. Questions?
