New ultra-sensitive test for Cancer and HIV developed by Stanford chemists

Tests being newer and ultra-sensitive have been designed for detecting diseases like cancer and HIV. This proves 10000 times more useful than latest diagnostic tools. This is said by Stanford Scientists. When diseases like HIV or cancer starts growing in bodies of patients, immune systems respond by production of antibodies.

Finding out these very antibodies is a great way to infer presence of HIV or cancer. The related biomarkers are also important to design a molecule which will bind itself to this biomarker and acts as an identifying flag. After a series of chemical reactions which are specialized, hereby known as immunoassay, the clinical scientists can isolate the flag. The attached biomarker and immunoassay provides proxy measurement of that disease.

Carolyn Bertozzi, professor of chemistry at Stanford University, US has added a well accomplished DNA technology to this standard procedure. A DNA strand is more powerful the antibody detection. ACS Central Science is the journal where the study was published.

It was tested against thyroid cancer and the sensitivity is 800 times the standard lab tests according to the US Food and Drug Administration (FDA). All this goes a long way in enhancing the invasive and non invasive lab tests for diagnosis of cancer and HIV. These diseases can be detected far earlier than their ability to progress and many of the health challenges in diagnosis can be cured.
