They are trying to put the “cure” in the manicure.
Researchers from Emory University and Georgia Tech developed a smartphone app to control anemia using images of a person’s nail beds instead of conventional blood test.
Anemia, which is believed to affect over 2 billion people all over the world, occurs when one does not have enough healthy red blood cells or hemoglobin to maintain oxygen in the body’s tissue.
The color of the nail bed reflects the amount of hemoglobin in the blood. Hemoglobin is the protein in the red blood cells that carries oxygen through the body and gives blood to its red sealing color.
When hemoglobin levels fall, nail beds appear more pleasant.
The powerful algorithm with it in the new application was tested in over 9,000 users whose nails were compared to their clinical blood test results.
Within seconds from the appearance of a nail photo, the technology estimated the level of hemoglobin with extraordinary accuracy.
When using a hemoglobin threshold of 12.5 g/dl to identify anemia, the application reached 89% sensitivity and 93% specification, numbers at the same time with traditional review methods.
For those with chronic anemia, there is a “personalization feature” in the application that can be calibrated to the initial base of a user by entering the results of the hemoglobin confirmed in the laboratory, along with the app estimates.
After personalization, the PPA performance approached the levels viewed in medical equipment cleared by the Food and Drug Administration for measuring non-invasive hemoglobin.
The results from this study were published this month in the procedures of the National Academy of Sciences.
Technology, now licensed in sanguine, has been made public available to download and has been used more than 1.4 million times in JSC
Traditional testing of anemia requires blood work, laboratory access and, in most cases, insurance coverage.
The team that stands after the app is hopeful that it will be revolutionary for those with chronic conditions such as kidney disease, cancer or nutritional deficiencies that require regular monitoring of hemoglobin.
Symptoms of anemiaJo Include fatigue, weakness, cold extremities, chest pain, pale skin, loss of appetite, breathing breathing, light light, headaches and desires for non-food objects-ice, soil, paper and even clay.
The widespread use of the application has discovered geographical and demographic models of anemia.
Android users, who usually spend less on their devices than iPhone users, showed lower levels of hemoglobin, suggesting a link between income and anemia.
Further analyzes show that countries with the highest average income, higher percentages of black residents, larger populations and more careful primary doctors – per capita had more applications.
Researchers claim that the application is not intended to replace medical care, but to support examination and monitoring, especially for those with chronic anemia and those living in remote or undeserved communities.
And the show has never been more critical.
Iron deficiencies like anemia compromise the immune system, making it harder for the body to fight the disease. Further, research found that anemia is present in 30% to 75% of patients with colorectal cancer.
