Testosterone EIA Test

...roid, is one of the most potent naturally secreted androgens [1]. In postpubertal males, testosterone is secreted primarily by the testes with only a small amount derived from peripheral conversion of androstenedione [2]. In adult women, it has been estimated that over 50% of serum testosterone is derived from...

LH IRMA Test

...wth, LH acts to stimulate theca cell production of androgens which are aromatized to estrogens in the granulosa cells. In the late follicular phase, the increased amounts of estrogen exert positive feedback on the hypothalamus and pituitary resulting in a GnRH surge and a peak of LH and FSH release [1,2]. The ...

DHEA EIA Test

... rapid peripheral tissue conversion to more potent androgens (androstenedione and testosterone) and estrogens may occur. In addition, DHEA has a relatively low affinity for sex-hormone binding globulin. DHEA is rapidly cleared from the circulation compared to the sulfated conjugate, DHEA-S. Measurement of ser...
