RE: Scientists Develop A Smart Phone App Which May Replace Blood Tests For Quantifying Hemoglobin Levels
+/- 2.4 g dL-1 error is great but only for early detection, that 1 g/dL can make a huge difference for special patients,,what about the quality of the photo taken by the camera, not all smartphones have similar resolutions? Is it taken into account or is there minimum requirements? Last but not least, I think it will be pretty cool if they make the app free for everyone 😂 😂😂 but I guess business is business...
Based on the data presented, it seems to have a lesser contribution than you might expect. Perhaps most phone cameras have sufficient resolution that an accurate enough color quantification is able to be achieved. I unfortunately don't have a better answer.
One would hope, but... yeah I doubt it.
Some of the Chinese phones have seriously poor resolution. I guess the app may have to compensate more in such devices given that it has a little marginal differences in detection between various skin tone. I share the same sentiment that the app should be free, let us be their test subjects and run tests for 'em :)
