اسم الاختبار: LH (IHC)
تكلفة الاختبار: 0 ریال
حالة عرض الاختبار: موجود
نوع العينة:
Teissu Formalin-fixed, paraffin-embedded (FFPE) tissue block
حجم العينة:
2 Unstained positively charged glass slide (25- x 75- x 1-mm) per test ordered; sections 4-microns thick
المعلومات السريرية:
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.
العوامل المتداخلة:
Age of a cut paraffin section can affect immunoreactivity. Stability thresholds vary widely among published literature and are antigen dependent. Best practice is for paraffin sections to be cut within 6 weeks.
