What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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.
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 Results may not be published yet.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.

Summary

This study is testing a new device that uses light (Raman spectroscopy) to measure blood sugar without needing a finger prick. Researchers will compare the device's readings to traditional blood tests in 49 people with diabetes. The goal is to see if this painless method is accurate and acceptable to patients.

What this could mean

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

Active substance
Raman spectroscopy device
What this could lead to
If successful, this could lead to a painless, needle-free way to check blood sugar, making diabetes management easier and more comfortable.
What could go wrong
This is a small, early-stage study with only 49 participants. The technology may not be accurate enough for everyday use, and results may not apply to everyone.

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: Age range: 18-75 years old. Gender: unlimited. Health status: patients with diagnosed diabetes or healthy volunteers. Nail health status: no obvious infection, discoloration, peeling and other lesions of the nail, so as to ensure the accuracy of Raman spectroscopy measurement. Willing to participate in the study and sign the informed consent. Exclusion Criteria: Nail diseases: such as fungal infections, psoriasis, trauma resulting in nail damage or deformity. The presence of factors that influenced the measurement results: Participants who used nail polish, fake nails, or nail products. Recent use of drugs containing heavy metals (which may affect nail composition) and skin conditions are not appropriate for such tests. Pregnant or lactating women. People with serious chronic diseases (such as terminal cancer, end-stage renal disease) or mental illness. Non-cooperation or inability to complete the entire research process, such as refusal or inability to complete Raman spectrum acquisition.
