The Estradiol ELISA is for the direct quantitative determination of Estradiol by enzyme immunoassay in human serum. FDA Registered. For In Vitro Diagnostic Use.
Estradiol is one of the main components of naturally occurring estrogens and is the major estrogen secreted during the menstrual cycle. The serum levels of estradiol are low during the follicular phase rising gradually until about one day before ovulation when a marked rise in the estradiol level occurs (Ovulatory Peak). The
estradiol level falls rapidly at, or right after ovulation and is again within the levels of the follicular phase. There is a second rise of estradiol around day 21 of the cycle (Luteal Peak). The levels then decline gradually to the
lowest level at the onset of the next menstrual cycle.
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.
