How to Properly Take Blood Tests and Undergo Ultrasound Examinations

Hello! Today, we’ll discuss how to properly take blood tests and undergo ultrasound examinations. Many people have questions about when and how to prepare for tests. Let’s go through it together!

Preparation for Blood Tests

Blood tests, such as general blood tests, biochemistry, and trace element tests, can be taken any day of the menstrual cycle, but not during menstruation. During menstruation, the hemoglobin level may be lowered, leading to additional tests.

Recommendations for Taking Blood Tests:

• Avoid taking blood tests during menstruation.
• Take blood tests on an empty stomach. Eating is not recommended, but drinking water is allowed and encouraged.

Hormonal Testing

As for hormonal tests, such as thyroid hormone tests (TSH, T4, T3), and other hormones, they can be taken on any day of the menstrual cycle.

Hormonal Testing at Different Phases of the Menstrual Cycle:

• On days 2-3 of the cycle, it is recommended to test for FSH, estradiol, prolactin, and other first-phase hormones.
• Progesterone should be tested only at the end of the cycle, when its level is the highest.

It is important to follow recommendations before taking tests: avoid sexual intercourse 24-48 hours before, get a good night's sleep, and avoid stress and anxiety.

Ultrasound Examinations

Ultrasound of the pelvic organs is best done on days 5-7 of the menstrual cycle. During this period, the endometrium is not yet thickened, and the condition of the uterus and ovaries can be assessed.

When to Do Ultrasound for Different Purposes:

• To determine ovulation, it is best to do the ultrasound on days 13-14 of the cycle.
• For diagnosing fibroids or endometriosis, it is best to do the ultrasound on days 5-7 of the cycle.

First Ultrasound During Pregnancy

If there are no concerns, the first ultrasound during pregnancy is recommended at 7 weeks. By this time, the gestational sac and embryo can be seen, and their heartbeat can be evaluated.

Breast Ultrasound

The optimal days for breast ultrasound are from days 5 to 10 of the menstrual cycle.

Preparation for Examinations:

• Avoid using vaginal suppositories or tampons for 3 days before the tests.
• Do not perform douching before the tests as it may affect the results.

Proper preparation for tests is crucial for accurate diagnostics. I hope our recommendations will be helpful, and your tests will go smoothly!
