50% of patients suffering
from a rare disease are
without an accurate diagnosis today.

accelRare® is a digital solution targeting the physicians of the primary care network to help them :
  • Identify a rare disease as soon as possible based on their patients’ symptoms,
  • Speed up the referral of their patient to the closest expert center.

Precious time saved for both the practitioner and the patient!

What is accelRare®?
A digital tool that :
  • Helps with pre-diagnosis of rare diseases
  • Is anonymous, secured, simple and convenient in 5 steps
  • Is aimed at primary care physicians (pediatricians, specialists and general practitioners)
  • Searches among 270 rare diseases for which treatment and/or an adapted care exist today and eventually among the 7,000 rare diseases identified to date
  • Offers an adapted and relevant orientation, as close as possible to the patient's home
  • Relies on a pre-diagnostic solution called MedVir, certified medical device for which Medical Intelligence Service is the legal manufacturer and Sanofi is the distributor
    It can in no way replace the advice and diagnosis provided by a healthcare professional. It is for informational purposes only.
What is MedVir?
It is a tool for pre-diagnosing diseases (820 common and urgent diseases to date)
  • From symptoms described by patients in their own words
  • Based on artificial intelligence and developed by Dr. Loïc Etienne
  • Resulting from 32 years of research and 14 years of use with 87% of accurate diagnoses (studies with the Lariboisière Emergency Department)
  • With prestigious references such as the CNRS and the APHP
  • Of which Medical Intelligence Service (MIS) is the legal manufacturer
