A new smartphone app can detect anemia without blood test
[vc_row][vc_column][vc_column_text]Emory University researchers have developed a cross-platform smartphone app which can test anybody for anemia with just one photo of their fingernails.
Anemia is the most common blood disorder, which affects nearly 2 million people all around the world. It is caused by the lack of red blood cells or hemoglobin in the body.
Doctors typically detect anemia through a blood test called Complete Blood Count (CBC). But now, a new mobile phone app can detect this blood disorder just by analyzing a photo of a person’s fingernails.
In a study published on Tuesday in Nature Communications, the team of researchers from Emory University explained how they trained an algorithm to analyze the colour of a person’s fingernail beds in a smartphone photo to determine the level of hemoglobin in their blood.
The authors noted in their paper published in the science journal, Nature Communications, “Here, we leverage this observation that pallor is associated with anemia to develop a method that quantitatively analyzes pallor in patient-sourced photos using image analysis algorithms to enable a noninvasive, accurate quantitative smartphone app for detecting anemia.”
The app works on the basis of an algorithm created by Wilbur Lam and his team at Emory University and detects anemia by assessing the concentration of hemoglobin from the colour of people’s fingernail beds, using photos taken on a smartphone.
The fingernail colour is a good indicator of the blood’s hemoglobin levels because our nails don’t contain any dark pigment-producing cells that would mask the telling hue.
Once the user takes the image of fingernails using the app, it uses the image metadata automatically obtained from the smartphone camera and normalizes for the background lighting conditions to accurately detect the actual colour of the fingernail bed. The paper claims that this is a technique missed in all previous non-invasive methods to detect anemia.
A four-week study conducted with the app involving 337 people with different blood conditions, including 72 healthy control subjects revealed that the app outperformed physicians assessing hemoglobin levels from a physical exam.
“All other ‘point-of-care’ anemia detection tools require external equipment, and represent trade-offs between invasiveness, cost, and accuracy,” researcher Wilbur Lam said in a press release.
He further said, “This is a standalone app whose accuracy is on par with currently available point-of-care tests without the need to draw blood.”
The researchers expect the app to be available to the public as soon as spring 2019. If that happens, detecting anemia will be as easy as snapping a photo.[/vc_column_text][/vc_column][/vc_row]

Apple launches iPhone 15 series, India price, features, availability
The iPhone 15 series will be available in India from September 22 but iPhone lovers can also pre-order, starting from September 15 onwards.
Apple launched its most anticipated iPhone 15 series, including the iPhone 15, iPhone 15 Plus, iPhone 15 Pro and iPhone 15 Pro Max during the Wonderlust event globally on September 12 night.
The iPhone 15 series will be available in India from September 22 but iPhone lovers can also pre-order, starting from September 15 onwards.
People can buy a new iPhone 15 or upgrade it to the old one. There are five colours available for the people.
According to reports, Apple has been manufacturing the iPhone 15 series in India and China. Apple has moved 7% of its iPhone production to India. Previously, India was not making the newest models. The Centre’s production-linked incentive (PLI) scheme for smartphones played a part in Apple moving its production to India.
The new iPhone 15 has been launched with the same starting price as its prototype, the iPhone 14. The 128GB variant is priced at Rs 79,900, while the 256GB variant costs Rs 89,900. For people who need more storage, the 512GB variant is available for Rs 1,09,900.
This latest iPhone series puffs a 6.1-inch display and comes in five different colours which are pink, yellow, green, blue, and black. While the design remains the same as the previous models, the iPhone 15 features a dynamic island notch instead of the usual notch, which was highly popular among the iPhone 14 Pro phones.
The camera part of the iPhone series has undergone significant upgrades, the new iPhone 15, with an enhanced 48-megapixel primary sensor replaces the 12-megapixel dual camera system which was available in the previous iPhone 14. This significant improvement promises better low-light photography and portrait shots.
The tech giant announced that the iPhone 15 has an all-day battery life, making it more convenient for users to go about their daily activities without worrying about their phone’s battery.
The iPhone 15 Pro models feature a lighter body and thinner bezels. The new AirPods Pro with USB-C charging case will support Lossless Audio with Apple Vision Pro.
Additionally, the iPhone 15 is powered by Apple’s A16 bionic processor, an upgrade from the A15 bionic chipset used in the previous iPhone 14 and iPhone 14 Plus models. The Pro models had the faster and better A16 chip, but now this feature is available in all iPhone 15 models.
The USB-C port on the standard iPhone 15 and iPhone 15 Plus remain limited to lightning speeds up to 480 Mbps. The iPhone 15 Pro and iPhone 15 Pro Max support USB 3 speeds up to 10 Gbps. People will need to buy a separate 1-meter Thunderbolt 4 Pro cable for Rs 5,724 or Rs 10,701 for the 1.8-meter cable to support faster speeds.
The dynamic island notch feature, which can adjust its size according to notifications, was widely discussed before the launch of the iPhone 15. This unique feature can now be available in all models of the phone.
Another important feature of the iPhone 15 is the shift to the USB Type C charging port. Apple has abandoned the lightning port in favour of the more commonly used USB Type C charging port. This means, there is no longer a need for a special iPhone charging cable to be carried around everywhere you go.
