This handout briefly describes the role of several important hormones measured in research.
Understanding IgE Allergy Test Results
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...
Improving Food Elimination Diets with IgG Testing
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 observe...

Stool-Based Biomarkers to Differentiate Between IBD and IBS
What are IBD and IBS? Inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS) are two different gastrointestinal tract issues affecting millions of people every day. Although there is some overlap between symptoms of IBD and IBS, differences still remain in regards to pathologies, risks...
Investigating Bioactive Leptin in Obesity Research
The Biology of Leptin Leptin is a hormone composed of 167 amino acids and is primarily produced by adipocytes, therefore providing a signal to the energy state of organisms. By binding to the leptin receptor, the analyte influences activity within the JAK-STAT pathway and thereby regulates energy m...
