The Estrone ELISA is a competitive immunoassay for the quantitative determination of estrone in human serum. For In Vitro Diagnostic use within the United States of America. FDA Registered. For In Vitro Diagnostic Use.
Estrone is a steroid like estriol and estradiol, belonging to the class of estrogens. The estrogens are involved in the development of female sex organs and secondary sex characteristics. Before the ovum is fertilized, the main action of the estrogens is on the growth and function of the reproductive tract to prepare it for the fertilized ovum.
During the follicular phase of the menstrual cycle the estrone level shows a slight increase. The
production of estrone then increases markedly to peak at around day 13. The peak is of short
duration and by day 16 of the cycle levels will be low. A second peak occurs at around day 21 of
the cycle and if fertilization does not occur, then the production of estrone decreases.
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...
The ALPCO Glucagon ELISA is for the quantitative determination of glucagon in human EDTA plasma. This assay was developed for ease-of-use and demonstrates superior sensitivity while eliminating cross-reactivity issues present in other commercially-available assays.
ALPCO’s automated turbidimetric solution for calprotectin testing offers enhanced efficiency without compromising clinical sensitivity or specificity. Clinicians can prioritize endoscopic evaluation for the patients that need it most and quickly put IBS patients on the right treatment path.
Join our speaker from Department of Pathology , University of Utah School of Medicine, Dr. Heather Nelson, to discuss how to validate and launch a FDA-approved assay.
