Hormone Levels

Hormone levels are influences when a gland produces too little or too much of a hormone. A common example is when the thyroid gland produces too little of the thyroid hormone. This causes hypothriosism. This means that the blood level of T4, main thyriod hormone, has too little and the TSH level will be high.

  • pregnancy failure (estriol)
  • perimenopause and menopause (estradiol)
  • polycystic ovarian syndrome (PCOS)
