Intended Use
Radioimmunoassay for the in vitro quantitative measurement of human Testosterone (TESTO) in serum. For in vitro diagnostic use only.
Testosterone is a C-19 steroid hormone (molecular weight: 288 Da) which is produced from androstenedione in the testes, adrenals and ovaries. Testosterone is a precursor along with androstenedione of the estrogen steroids.
Clinical significance of testosterone level
Source of testosterone :- Women : Ovary, adrenal cortex, peripheral tissues (by conversion of 50-60% other steroids).
- Men : Testes > 90%, adrenal cortex, peripheral tissues.
- Women : Hirsutism and virilization, polycystic ovary syndrome, congenital adrenal hyperplasia (with 170H-PROG), tumors of adrenal and ovarian origin, breast cancer.
- Men : Disease of the hypothalamic pituitary unit, some malignant testicular tumors, congenital adrenal hyperplasia, prostate cancer.
Clinical diseases with low level of testosterone
Primary or secondary hypogonadism, Klinefelter's syndrome, other chromosomal alteration, hypopituitarism, enzymatic defects, orchidectomy and cryptorchidism, testicular feminization, hepatic cirrhosis, some autoimmune diseases for example : Sjögren's syndrome, systemic lupus.
Other domains for measurement of testosterone level :- In vitro fertilization : the women with high respons to gonadotrophin have a significant increase in testosterone.
- Parameter of the prepuberty and puberty.
- Determination of foetal sex in amniotic fluid.
- Free testosterone is significantly raised in both male and female acne sufferers.
- Follow up of cancer and in pathological situations; low testosterone syndrom.
