Researchers Develop Portable Device for Testing Cancer Biomarkers
Researchers at Brock and McMaster universities have developed a prototype for a tool which will allow patients to use a blood sample to test for the presence of cancer biomarkers. This technology has specifically been designed to assess the levels of prostate-specific antigens (“PSA”), but it can be tweaked to test for other cancers as well. According to the researchers, the device operates in just the same way that hand-held glucose monitors work. A patient just mixes a tiny drop of blood in a vial which contains a reactive fluid, and then a sample from this mixture is placed on…
