A new smartphone app can detect anemia without blood test

Published

[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]

Samsung Galaxy S25 FE may skip chip upgrade, could reuse Exynos 2400e

Samsung’s next Fan Edition smartphone, the Galaxy S25 FE, is likely to feature the same Exynos 2400e processor as last year’s model, according to new leaks.

Samsung appears to be following a conservative route for its upcoming Galaxy S25 FE, with reports suggesting that the smartphone will feature the same Exynos 2400e chipset used in last year’s Galaxy S24 FE. While the tech giant has not officially confirmed the device’s launch, leaks hint that the handset—codenamed R13—is already under development.

According to internal code seen by the media, the Galaxy S25 FE carries the codename siop_r13s_s5e9945, confirming its chipset as Exynos 2400/2400e. This is the same processor seen in the Galaxy S24 FE, indicating that Samsung may skip a processor upgrade this year.

If accurate, this decision places the S25 FE behind newer premium chipsets like the Snapdragon 8 Gen 3, Snapdragon 8 Elite, and MediaTek Dimensity 9400, potentially making the device less powerful in comparison to flagship competitors in 2025.

The Galaxy S25 FE is expected to launch towards the end of Q3 or early Q4 2025, as a more affordable variant of the Galaxy S25 series. Much like its predecessor, it will likely aim to strike a balance between performance and price, appealing to cost-conscious consumers.

Last year’s Galaxy S24 FE, launched in September 2024, came at a price of Rs. 59,999 for the 8GB + 128GB model. It featured a 6.7-inch FHD+ Dynamic AMOLED display with 120Hz refresh rate, 50MP triple rear camera, 10MP selfie camera, 4700mAh battery, and support for Galaxy AI features. If Samsung follows suit, the S25 FE could retain many of these specifications, making only minor hardware or software tweaks.

The report also mentions that the Indian variant of the Galaxy M36 5G may be powered by the Exynos 1380 chipset, the same one used in the Galaxy M35 5G. This suggests Samsung might be keeping things uniform across its mid-range portfolio for 2025.
