Androstenedione is produced by the adrenals and gonads. As a result, the determination of the
level of androstenedione in serum is important in the evaluation of the functional state of these
glands. Androstenedione is a precursor of testosterone and estrone. Besides the adrenals, in females, the ovaries have been shown to be an important source of androstenedione. It has been reported that there is a fluctuation day by day of androstenedione during the ovulatory cycle.
The principle production of testosterone in females is from the conversion of other related
androgens, especially androstenedione. An abnormal testosterone level in women should be
accompanied by the estimation of serum androstenedione. The use of serum testosterone
determination in conjunction with the enzyme immunoassay of androstenedione can be used to
determine if the source of the excess androgen production is adrenal or ovarian.
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...
