New Blood Test for MS Developed

Researchers from a laboratory based in Glasgow, Scotland in the United Kingdom have announced that it has developed a new blood test which can detect certain chemicals that is associated with the deterioration of nerve cells in people with multiple sclerosis. The blood test, according to the researchers, can aid doctors to track the progression of MS and help them determine when the patients are about to enter into the next stage of deterioration.

The laboratory of Glasgow Health Solutions, which is headed by Dr. Tom Gilhooly, has developed a test called the Tyscore Array. This test can be used to measure the level of a chemical known as nitrotyrosine, a substance that acts as an indicator of cell inflammation and damage associated with people suffering from multiple sclerosis. The test is then used as a biomarker for peroxynitrite activity which is thought to cause the deteriorating nerve damage associated with MS.

Despite this development and the claims, there are some people who might be taking this news with a grain of salt. One is Dr. Laura Bell, the Research Communications Officer at the MS Society. She said, "Yes, there is some science that suggests nitrotyrosine levels are raised in people with MS, but its value as a biomarker simply has not been validated and therefore interpretation of the results would be open to question."

Dr. Bell further added, "Also, there are currently no biomarkers known to predict MS, either in the blood or urine and no drugs to suppress nerve loss or indeed progression in secondary progressive MS or primary progressive MS anyway, so a positive result would not lead to a change in treatment or diagnosis."

Research on finding an effective biomarker for MS is currently undergoing, with the MS Society included among many other research firms. Using nitrotyrosine levels in the body as a biomarker for MS is still open for further study. "It’s also worth remembering that nitrotyrosine levels could be induced by a number of different things including infections. People with progressive MS are more likely to get infections, particularly urinary tract infections, and this would confuse the results", added Dr. Bell.
