Androstenedione ELISA Kit

  • Created on the 15 February, 2017.

BACKGROUND

Androstenedione (also called 4-Androsten-3, 17-Dione) is a steroid hormone which is produced by either the adrenals or the gonads, it is a very important precursor for estrone and testosterone. This gives it an important role in evaluating the functional state of these glands by simply measuring the levels of androstenedione present in serum. Androstenedione and testosterone have been known to show a high diurnal variability, where the morning sample displays the highest levels that are usually measured during the day. There are reports that indicate day by day fluctuation for androstenedione levels during the ovulatory cycle. Also, during pregnancy and at the age of puberty the serum levels of androstenedione are found to increase whilst it decreases again following menopause.

There is high circulating androstenedione levels are identified in women with 21-hydroxylase effect and polycystic ovaries. In general the overproduction is usually as a result of ovarian dysfunction or could be of adrenal origin. Whereas, a significantly reduced level of androstenedione is found in postmenopausal osteoporosis patients.

INTENDED USE

Human androstenedione ELISA kit is a reliable quantitative procedure for measuring androstenedione (17-Dione, 4-Androsten-3) in human serum and plasma (EDTA). This assay has a minimum sensitivity detection limit of 0.021 ng/ml.

SENSITIVITY

The minimum sensitivity detection limit of androstenedione (17-Dione and 4-Androsten-3) using this human androstenedione ELISA kit was approximately 0.021 ng/ml. The dynamic assay range for this kit is 0.1 – 10.0 ng/ml.

I carried out a pilot study comparing the performance of many ELISA kits from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
