17a-Hydroxypregnenolone

17a-Hydroxypregnenolone is an intermediate in the synthesis of steroid hormones and may be related to the synthesis of sex hormones or adrenal hormones. The sulfate form of 17a-Hydroxypregnenolone (17α-hydroxypregnenolone sulfate) is the main interfering substance in neonatal plasma, which can significantly affect the immunoassay results of 17α-hydroxyprogesterone (17-OHP) by cross-reacting with antibodies[1].
