Glial Fibrillary Acidic Protein (GFAP) is the principal 8-9 nm intermediate filament in mature astrocytes of the Central Nervous System (CNS). The findings showed that GFAP is released after traumatic brain injury severity and outcome into the blood very soon after traumatic brain injury (TBI), and that GFAP is not released after multiple trauma without brain injury. In the CNS following injury, either as a result of trauma, disease, genetic disorders, or chemical insult, astrocytes become reactive and respond in astrogliosis. Astrogliosis is characterized by rapid synthesis of GFAP. GFAP normally increases with age and there is a wide variation in the collection and processing of human brain tissue. GFAP is also an established biomarker of retinal stress.

1. What percentage of your IgE allergy testing panel consists of molecular allergens rather than allergen extracts? The ALEX2 IgE allergen panel consists of 117 extracts and 183 molecular allergens. This represents the largest panel of molecular allergens on the market, including 50 unique...
Cases of food and environmental allergies have been increasing over the last decade. While conservative estimates suggest IgE-mediated allergy affects 6-8% of children and 2-3% of adults, some estimates are as high as 30%.3, 2 Symptoms can range from mild to severe and include itching, hives,...
Food sensitivity or food intolerance involves a non-allergic response to a food or food additive. In a recent on-line survey conducted in the U.S., 24% of adults aged 18 to 79 reported a food intolerance. While a food allergy is typically mediated by IgE antibodies, adverse reactions to food...
In a head-to-head comparison of FDA-cleared assays and a novel ALPCO method, investigators observed wide variability in specificity and false-positive rates across platforms, raising important questions about standardization and clinical interpretation.
