Inhibin Alpha (In the pipeline)
Inhibin Alpha, also known as INHA, is a peptide hormone belonging to the transforming growth factor-beta (TGF-beta) family. It is produced by ovarian granulosa cells in female follicles and by Sertoli cells in the male seminiferous tubules, with the purpose of inhibiting the release of follicle-stimulating hormone, and is also found in the prostate, brain, and adrenal glands. This marker has proven effective in aiding with a number of differential diagnoses, including distinguishing between adrenal cortical tumors and renal cell carcinoma, and between intrauterine and ectopic pregnancy in endometrial curettage. Anti-Inhibin Alpha can also be used to detect for sex cord stromal tumors of the ovary as well as trophoblastic tumors.
