Biomedical engineers have developed a novel smartphone application that allows anemia to be detected non-invasively without the need for blood.
The app uses photos of a person's fingernails taken on a smartphone to accurately measure how much hemoglobin is in the blood.
Fingernail beds are ideal for detecting anemia because they contain no melanin – the pigment that gives color to the skin, hair and eyes of people – suggesting that the test suitable for people with a variety of patients is skin tones.
"All other point of care anesthesia detection tools require external equipment and represent a compromise between invasiveness, cost, and accuracy," said lead investigator Wilbur Lam, an associate professor at Emory University in the US.
"This is a standalone app that meets the accuracy of current point-of-care tests without having to draw blood," said Lam.
The app is especially useful for pregnant women and women with women Abnormal menstrual bleeding, runners / athletes and patients with chronic anemia can monitor their disease and determine the times when they need to adjust their therapies or receive transfusions the explorers.
The app, detai In the journal Nature Communications led, he is part of the doctoral thesis of the former student of Biomedical Engineering, Rob Mannino, who from his own experience with beta-thalassemia, a hereditary blood disorder that reduces the production of hemoglobin Has motivated research.
Maninno photographed before and after the transfusion first as his hemoglobin value changed.
Later, the researchers studied fingernail photos and correlated the color of the fingernail beds with the hemoglobin content measured by complete blood count (CBC) measurement of 337 subjects.
The results showed some healthy and others with a variety of anemia diagnoses.
However, further research is needed to ultimately achieve the accuracy that replaces the blood test of anemia for clinical diagnosis, the team said.
The smartphone anemia app is expected to be available for public download in 2019.
