Hormone Blood Tests in Busan

Hormone blood tests help explain irregular or missed periods, acne or excess hair growth, fertility concerns and menopause symptoms. Busan OB/GYN clinics can draw blood on site, and results for most tests come back within a few days.

Common female hormone tests

• FSH and LH: pituitary hormones that control ovulation. They're used to assess ovarian function, PCOS and menopause.
• Estradiol (E2): the main estrogen. It's often checked alongside FSH early in the cycle.
• Progesterone: measured in the second half of the cycle to confirm ovulation.
• AMH: reflects the remaining egg supply (ovarian reserve). It can be tested on any day.
• Prolactin: high levels can stop periods or cause nipple discharge.
• Thyroid (TSH, free T4): thyroid problems commonly affect periods and fertility.
• Testosterone and other androgens: checked when PCOS or excess hair growth is suspected.

When to get tested

Timing matters. FSH, LH and estradiol are usually drawn on day 2 to 5 of your cycle (day 1 is the first day of full bleeding). Progesterone is typically checked about a week before your next expected period. If your periods are very irregular, the doctor will choose a timing for you. Some tests, such as prolactin, may be more accurate in the morning, so ask whether you need to fast or come early.

What the visit involves

The doctor reviews your symptoms and cycle history, and may do a pelvic ultrasound at the same visit to look at the ovaries and lining. Blood is drawn at the clinic. Results are usually ready within a few days, though some specialized tests take longer. Book a follow-up to go over what the numbers mean, since a single result often needs context or repeating.

Cost and insurance

When hormone tests are ordered to investigate symptoms or a diagnosis such as irregular periods or suspected PCOS, many are partly covered by NHI. Tests requested for general screening, and some specific tests such as AMH in certain situations, may be self-pay. Coverage depends on the medical reason, so ask the clinic for an estimate before blood is drawn.

Tips for foreigners

• Bring your ARC or passport, and note the first day of your last period.
• Bring any earlier results from your home country. Units can differ, so the doctor can compare them.
• Ask for a printed copy of your results.
• See the international patients guide for language help.
