A new test could flag people at risk for anemia by filming their eyeballs — no needles required
A new needle-free test has been developed to estimate red blood cell counts by filming the eye. This technology could serve as a preliminary screening tool for anemia, particularly in low-resource settings. While promising, it is not yet ready to replace traditional blood tests and requires further validation.
- ▪The test uses videos of the eye to estimate red blood cell levels without needles.
- ▪In trials, the technology identified anemia over 80% of the time among 224 participants.
- ▪Experts believe it could improve access to blood monitoring in resource-limited environments.
