The Dehydroepiandrosterone Sulfate ELISA is intended for the direct quantitative determination of DHEA-S by enzyme immunoassay in human serum. FDA Registered. For In Vitro Diagnostic Use.
Dehydroepiandrosterone sulfate (DHEAS) is produced by the adrenals and gonads. As a result,
the determination of the level of DHEAS in serum is important in the evaluation of the functional
state of these glands. DHEAS is a precursor of testosterone and estrone. Besides the adrenals
in females, the ovaries have been shown to be an important source of DHEAS. It has been
reported that there is a fluctuation day by day of DHEAS in women during the ovulatory cycle.
The principle production of testosterone in females is from conversion of other related androgens, especially DHEAS. An abnormal testosterone level in women should be accompanied by the estimation of serum DHEAS. The use of serum testosterone determination in conjunction with the ELISA of DHEAS can be used to determine if the source of excess androgen production is ovarian or adrenal.
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.
