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 This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
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 Results may not be published yet.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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This study tests whether a non-invasive device that uses light to measure hemoglobin through the skin can accurately detect anemia. Researchers will compare its readings with standard blood tests in 150 adults in Jakarta. If the device proves reliable, it could offer a quick, painless way to screen for anemia in community settings.

What this could mean

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

Active substance
non-invasive spectrophotometric hemoglobin measurement device
What this could lead to
If successful, this could enable quick, painless anemia screening in community settings without blood draws.
What could go wrong
This is a small, early validation study; the device may not match the accuracy of standard lab tests, and results may not apply to other populations.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Adults aged 18 years and older participating in community-based health screening activities in Jakarta. Participants include both healthy individuals and individuals with potential anemia or other underlying medical conditions. All participants undergo non-invasive hemoglobin measurement, capillary hemoglobin testing using POCT, and venous blood hemoglobin measurement using an automated hematology analyzer during a single study visit.

Accepted

You do not need to have the condition being studied to take part.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adults aged 18 years and older. * Residents or community members participating in community health screening activities in Kelurahan Kota Bambu, Jakarta. * Willing to undergo non-invasive hemoglobin measurement. * Willing to undergo capillary blood hemoglobin testing using point-of-care testing (POCT). * Willing to undergo venous blood collection for hematology analyzer examination. * Able to provide written informed consent. Exclusion Criteria: * Active bleeding at the time of examination. * Severe acute illness requiring urgent medical attention. * Refusal to undergo finger-prick or venous blood sampling. * History of severe anxiety, syncope, or adverse reactions related to blood collection procedures. * Visible infection, wound, or skin lesion at the measurement site. * Severe hand deformity preventing proper non-invasive measurement. * Nail polish or artificial nails that cannot be removed before examination. * Markedly cold hands or poor peripheral perfusion that may interfere with optical measurements. * Incomplete hemoglobin measurement data from any of the study methods.
