What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.

Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tests whether a smartphone app can accurately detect anemia by analyzing images of the lower eyelid. The app uses artificial intelligence to estimate hemoglobin levels without a blood draw. Researchers will compare the app's results to standard lab tests in 3,000 adults who are hospitalized or in outpatient care.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
AnemIA App (AI-based smartphone application)
What this could lead to
If accurate, this app could enable quick, needle-free anemia screening in clinics or remote areas, improving early detection.
What could go wrong
The app's accuracy may vary across skin tones or lighting conditions, and it is not yet proven in real-world settings.

The number who actually took part.

Started

Mar 2026

Expected to finish

Dec 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.
