Blood

New research is suggesting high levels of a certain blood-based biomarker may serve as an early warning sign of Alzheimer’s disease, two years before symptoms develop. The preliminary study has yet to be verified in larger cohorts of patients.

Cancer is often hard to detect until it’s too late. But that might be about to change. Researchers have developed a new AI-powered blood test that can accurately detect over 50 different types of cancer and even identify where it is in the body.

Last week the FDA approved the experimental use of blood from recovered COVID-19 subjects as a treatment for newly infected patients. The therapy harks back to the 1890s, and it may be the stop-gap we need while other treatments are in development.

A new study led by researchers from UC San Diego is suggesting unique microbial DNA signatures detected in blood samples can not only potentially identify dozens of different cancers but also catch the disease in its earliest stages.

Two new studies are demonstrating the development of diagnostic tests to detect prostate cancer. The research presents a urine test that can detect the disease in its early stages and a blood test that may catch the cancer as it begins to metastasize.

Some exciting advances are being made when it comes to blood-testing for Alzheimer's, with the latest example offering a way to spot a traditionally hard-to-detect protein called tau, which is considered a key biomarker of the disease.

When Parkinson’s patients are diagnosed with the condition, there are still many unknowns around how the disease will impact their lives. While it is no crystal ball, a new blood test is offering hope of better patient management.

A couple of years ago, we heard about a robotic device that was designed to draw blood samples. And while it had only been tested on artificial arms at the time, it's now been successfully trialed on real live humans.

People with diabetes prick their fingers and test their blood glucose levels several times a day. But now researchers at MIT have developed a less invasive method using infrared light to take glucose readings from fluid just below the skin's surface.

Researchers have discovered a new component in blood that has never been detected there before. Mitochondria are normally found inside cells, but the team has now discovered them floating around on their own in the bloodstream.

Research has confirmed chemicals in sunscreen can be detected in the blood of users after just one application. But experts urge people continue using sunscreen as there is no evidence to suggest these findings point to negative health consequences.

Researchers have developed what they are calling “super-human red blood cells.” These are normal red blood cells loaded with synthetic drug molecules, creating a powerful hybrid cell designed to deliver drugs to targeted locations in the body.
