Millions of people are dying due to ischemic stroke, transient ischemic attack, blood clots in the brain and other neurological problems. These types of sudden strokes and attacks are prevalent in every country and the number of deaths due to these types of diseases is increasing steadily over the years. Blood pressure patients are susceptible to sudden stroke and brain hemorrhage and people suffering from high blood pressure should undergo a unique blood test namely IHC-Glial-Fibrillary-Acidic-Protein (GFAP). Individuals who suffered from grievous head injuries should also undergo GFAP blood test to rule out blood clots and other neurological problems.
