The underlying instruments have different purposes: the Canadian Consensus Criteria and ACR criteria are clinical criteria frameworks, while FUNCAP-27 is a validated functional-capacity questionnaire. Elara digitizes questions and response options and, for score-based instruments, the published scoring logic; Elara does not determine whether a diagnosis or criteria status is present.
They stay in your browser. Questions and scoring run locally on your device and the result is stored encrypted in session storage. Your answers are never transmitted to us and are not linked to any account. Only if you voluntarily leave your email address at the end do we store that — without your answers. Use of the page itself is measured statistically if you consent in the cookie banner.
Yes. You can export your result as a PDF and share it with your physician. It makes preparing for complex symptom conversations much easier.
The ME/CFS symptom check takes 5–10 minutes, the fibromyalgia check about 5 minutes. FUNCAP-27 for functional-capacity assessment is longer, taking 15–25 minutes.
The summary shows the answers you gave in the covered areas and the scores calculated from them. It does not determine whether a condition is present. You can use it as a structured starting point for a medical conversation.
Record symptoms, exertion and recovery every day and see patterns over weeks.
