Cancer with saliva test

Test saliva is one of the future applications of the equipment lab-on-a-chip, which was developed as microfluidics technology. Scientists explained that saliva contains blood all kinds of work, but at concentrations 1,000 to 10,000 times smaller. What is interesting particles dissolved in saliva and other secretions in the mouth, which means scientists need instruments with sensitivity 1.000 to 10,000 higher than that used for the examination of blood samples now. Advances in nanotechnology have enabled researchers to reveal biomarkers even at very low concentrations.

A team consists of multi-disciplin of biologist, chemist, proteomics leaderships, engineers, and computer scientists are working together to create a list of chemical composition of the protein found in saliva. So far, they have identified 1166 different proteins.

By knowing this protein, doctors can detect early signs of oral cancer, breast cancer, and autoimmune disease Sjogren's syndrome. Soon, ..... the group hopes to find proteins associated with cervical cancer and others. Researchers predict that early diagnosis will greatly increase the chance of a doctoral far to treat this cancer.

In fact said, checking the saliva is better even cheaper than blood serum test, and provide test results tidah more than 30 minutes. This test is easier and less painful for children and people who needle phobia.
