Hormone
Tests

For those with symptoms or diseases associated with hormonal abnormalities, hormone testing is crucial. Hormone testing is frequently necessary for women with irregular periods, PCOS, infertility problems, or menopausal symptoms, as well as for males experiencing signs of low testosterone, such as mood swings, exhaustion, or decreased libido. Testing is also beneficial for people who have symptoms of suspected thyroid issues, such as fatigue, temperature sensitivity, or unexplained weight fluctuations.

People with Addison's or Cushing's syndrome symptoms, chronic fatigue, or stress intolerance can benefit from an adrenal hormone evaluation. For infertile couples, people with inexplicable symptoms like mood swings or insomnia, and athletes tracking hormones linked to performance, testing is essential. Testing may also be necessary for those with metabolic disorders, such as insulin resistance or trouble losing weight, or aging-related symptoms, such as memory problems or poor energy.

Furthermore, specific evaluations could be necessary for people with uncommon genetic or endocrine disorders. Depending on symptoms and medical history, speaking with a healthcare professional might help determine whether testing is necessary.

The timing of hormone tests varies depending on the particular hormone being checked and its function. Hormone tests are performed for a variety of reasons. To assess ovulation, fertility, or irregular menstruation, females can test for reproductive hormones like FSH and LH on days two through five of the menstrual cycle. Estradiol is frequently checked at the start of the cycle, but progesterone is typically measured on day 21 of the cycle or seven days following ovulation to confirm ovulation. Prolactin levels can be measured at any time, although morning fasting is recommended for accuracy, and pregnancy-related hormones such as hCG are examined to confirm pregnancy.

Hormone testing for men is usually performed to assess endocrine problems, sexual health, and fertility. The most often examined hormone is testosterone, which is often evaluated in the morning when levels are at their highest. Sperm production and general reproductive health are evaluated by testing other hormones, such as FSH and LH. If symptoms like exhaustion decreased libido, or unexplained bodily changes point to imbalances, tests for prolactin, thyroid hormones, or cortisol may also be performed. Although the timing of these male hormone tests is less cycle-dependent, accuracy may still need early sampling.
