Biomarkers of Acute Stroke in Clinic

"The ISCDX test is based on gene expression changes that occur as a result of the ischemic stroke. When the stroke occurs, the immune system in the body reacts and causes changes in gene expression in several types of cells, including white blood cells, related to activation of innate and adaptive immune systems.~The ISCDX test distinguishes between cardioembolic and large artery atherosclerotic origin of stroke using a gene signature. The pattern or signature of up or down regulation for all genes for a patient determines whether the patient's pattern of gene expression is more like the pattern seen in other cardioembolic patients or more like the pattern seen in patients with large artery atherosclerotic cause of stroke."
