Androstenedione ELISA Kit


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


Androstenedione (also called 4-Androsten-3 or 17-Dione) is a steroid hormone that 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 4-Androsten-3 levels present in serum.

There are reports that indicate day by day fluctuation levels during the ovulatory cycle. Also, during pregnancy and at the age of puberty the serum levels are found to increase whilst it decreases again following menopause. There is also high circulating levels that has been 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 an adrenal origin.

Furthermore, 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.


All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA assay performed well and I was happy with the results that were generated.

J. Thomas
Senior Technician / Addenbrooke’s Hospital

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