This new blood test could detect cancer before it shows up on scans

A new CRISPR-powered light sensor can detect the faintest molecular signs of cancer in a drop of blood. A new light-based sensor can spot incredibly tiny amounts of cancer biomarkers in blood, raising the possibility of earlier and simpler cancer detection. The technology merges DNAnanotechnology, CRISPR, and quantumdots to generate a clear signal from just a few molecules. In lung cancer tests, it worked even in real patient serum samples. Researchers hope it could eventually power portable blood tests for cancer and other diseases.

Scientists have designed a powerful light based sensor...

A simple blood test can help detect cancer in patients with non-specific symptoms such as fatigue, pain or weight loss. This is according to a Swedish study from Karolinska Institutet, Danderyd Hospital and others, published in Nature Communications.

When patients seek care for non-specific symptoms such as fatigue, pain or weight loss, it is often difficult to determine whether the cause is cancer, another serious condition or something completely harmless.

In a new study, researchers at Karolinska Institutet and Danderyd Hospital, together with Örebro University, KTH Royal Institute of Technology and SciLifeLab at Uppsala University, have investigated whet...

Using the results of a standard blood test and an online tool, you can find out if you are at increased risk of having a heart attack within six months. The tool has been developed by a research group at Uppsala University in the hope of increasing patients’ motivation to change their lifestyles.

Their paper is published in the journal Nature Cardiovascular Research.

Heart attacks are the most common cause of death in the world and are increasing globally. Many high-risk people are not identified or do not take their preventive treatment.

Now, researchers led by Professor Johan Sundström at Uppsala University have found that heart attacks can be predicted with a standard blood test...

An analysis of a clinical trial of more than 2,500 people with Type 2 diabetes and kidney disease found that high levels of four biomarkers are strongly predictive for the development of heart and kidney issues.

A simple blood test may predict the risk of progressive heart and kidney disease in people with Type 2 diabetes and kidney disease, according to new research published today in the American Heart Association’s flagship journal Circulation.

“High levels of certain biomarkers are indicators of heart and kidney complications and may help predict future risk of disease progression,” said lead author James Januzzi, M.D...
