How to Properly Prepare for Hormonal Testing?

Hormonal testing is an important part of diagnosing various diseases. Doctors prescribe it for menstrual cycle irregularities, fertility problems, metabolic disorders (such as obesity), hirsutism (excessive hair growth), mood swings, blood pressure changes, and fatigue. To ensure accurate test results, it is crucial to prepare properly.

Recommendations Before Hormonal Testing

• For 24 hours before the test, avoid sexual activity, visiting saunas and baths, and breast palpation.
• For three days before the test, refrain from intense physical activity and stress.
• On the day of the test, ensure you have a good night's sleep, feel relaxed, and go to the lab calmly.
• Avoid smoking before the test. It’s best to quit smoking altogether.
• The test should be done on an empty stomach, preferably before 10 a.m.
• Do not take the test during a cold or if you have a fever.
• If you are taking hormonal medications, such as combined oral contraceptives, they should be stopped 2-3 months before the test.

When Should Hormonal Tests Be Taken?

Test results depend on the day of the menstrual cycle. Here are the main recommendations:

Days 2-5 of the Cycle

• Luteinizing Hormone (LH)
• Follicle-Stimulating Hormone (FSH)
• Estradiol
• Prolactin
• Total Testosterone and Free Testosterone Index
• Dehydroepiandrosterone Sulfate (DHEA-S)
• 17-Hydroxyprogesterone (17-OHP)

Days 19-22 of the Cycle

Progesterone: This hormone should be tested 7-9 days before the expected start of menstruation. For women with an irregular cycle, the timing is calculated individually.

Thyroid Hormones

• TSH (Thyroid-Stimulating Hormone)
• Free T3 and T4
• Antibodies to TPO (Thyroid Peroxidase)

These tests can be done on any day of the cycle.

Insulin and HOMA Index

The indications for these tests are not related to the menstrual cycle, so they can be done on any day.

Why is Preparation Important?

Hormones are highly sensitive to external factors. Improper preparation can distort results, leading to unnecessary treatments. Follow these recommendations to get accurate data and avoid diagnostic errors.
