Follicle Stimulating Hormone (FSH)




Human FSH is secreted by the gonadotropic cells of the anterior lobe of the pituitary gland in response to gonadotropin releasing hormone (GnRH) from the medial basal hypothalamus. In the female, hFSH stimulates follicular growth and, in conjunction with hLH, stimulates estrogen secretion and ovulation. Following ovulation, hFSH and hLH are believed to be responsible for the transformation of the ruptured follicle into a corpus luteum and to influence the secretion of progesterone by the luteal cells

Chemiluminescent immunoassay (CLIA)


Patients who have been regularly exposed to animals or have received immunotherapy or diagnostic procedures utilizing immunoglobulins or immunoglobulin fragments may produce antibodies, e.g. HAMA, that interfere with immunoassays.

All results should be interpreted in light of the total clinical presentation of the patient, including: symptoms, clinical history, data from additional tests and other appropriate information.
