Clinical Info

Use for monitoring patients with stromal granulosa cell tumors of the ovary and ovarian epithelial tumors of the mucinous type with inhibin B overexpression. Inhibin B is an endocrine marker to aid in the monitoring of gonadal function. In males, inhibin B may aid in the assessment of spermatogenesis and testicular function. In females, it may be useful in the assessment of ovarian reserve and activity, and oocyte quality. This test is performed using the ANSH ultra-sensitive Inhibin B ELISA kit. Values obtained with different methodologies or kits cannot be used interchangeably.
