وضعیت ارائه آزمایش : موجود
نوع نمونه :
Teissu Formalin-fixed, paraffin-embedded (FFPE) tissue block
حجم نمونه :
2 Unstained positively charged glass slide (25- x 75- x 1-mm) per test ordered; sections 4-microns thick
اطلاعات بالینی :
In male individuals, luteinizing hormone (LH) stimulates androgen production by Leydig cells in the testis. In female individuals, LH stimulates androgen and progesterone synthesis in ovarian follicles and corpus luteum and promotes ovulation. A sparse population of cells (approximately 10%) stain positively in normal pituitary gland. This population of gonadotrophs also produces follicle-stimulating hormone. Immunohistochemical detection of LH beta may be useful in the classification of pituitary adenomas.
