New app measures hemoglobin level by selfie

A new application measures the level of hemoglobin by selfie. It will allow you to diagnose many diseases at an early stage – for example, anemia.

Researchers at Indianapolis University have come up with a way to measure hemoglobin in the blood using eyelid photographs taken on a smartphone. This is one of the most common clinical laboratory tests. Now it can be done without visiting the clinic – this will facilitate the monitoring of critically ill patients, as well as improve care in low- and middle-income countries where access to laboratories is limited.

“The new mobile approach will allow you to remotely measure blood hemoglobin levels to detect anemia, acute kidney damage, and hemorrhage, to determine sickle cell anemia,” said Young Kim, head of the research team. “The pandemic has greatly increased the need for such analyzes.”

The researchers used software to convert the smartphone’s built-in camera to a hyperspectral tomography that measures hemoglobin levels without the need for any hardware modifications or accessories. Pilot clinical testing with the participation of volunteers showed that the errors in prediction when using a smartphone are in the range from 5 to 10%.

“The new technology can be very useful in detecting anemia, which is characterized by low levels of hemoglobin in the blood,” Kim added. “This is a major public health problem in developing countries.”
