A drop of blood to diagnose cancer and other diseases

Scientists from the Russian University of Samara, in cooperation with scientists from the Medical University of Samara, have discovered a rapid way to diagnose cancer and other diseases using blood spectroscopy.

The Journal of Raman Spectroscopy reports that, according to the researchers, this method allows a liquid biopsy to be performed in a matter of minutes, unlike analytical methods used in the laboratory which generally take hours. Raman spectrometry enables real-time analysis of blood components, cell type and concentration.

“Light can interact with the biological molecules that make up the building blocks of our body. If we know how this process takes place, we can follow from a single drop of blood the changes in body composition, and if it develops, ”says Ivan Brachenko, assistant professor in the department of laser radiation and biotechnology at the University of Samara. There are some diseases and this analysis can be done in a few minutes. “

Suggested method

He pointed out that scientists around the world are looking for ways to obtain high-precision indicators and general diagnostic methods. The method proposed by the researchers, although less precise than the laboratory methods currently used, can be implemented with portable equipment.

According to the researchers, the use of liquid biopsies and portable equipment significantly reduces the costs of blood tests. “The results obtained can be useful during comprehensive examinations. Because with the help of liquid biopsy, people with the disease in the early stages of its development can be quickly detected and referred to a specialist. This method can also be used to monitor the condition of patients on treatment, ”explains Prachenko. Their condition has improved or worsened, so a liquid biopsy will certainly reveal it. “
