Is it accurate to check hormone levels on the first day of menstruation?

Hormone testing is mainly to detect whether the endocrine system in women is normal, which plays a very important role in ensuring women's physical health. If a woman's hormone level is not within the normal range, it means that there is a problem in some aspect of her body and she needs timely treatment. In addition, hormone tests should also be conducted within a scientific time frame. So, is it accurate to check hormone levels on the first day of menstruation?

By measuring sex hormone levels, we can understand women's endocrine function and diagnose diseases related to endocrine disorders. The six commonly used sex hormones, namely follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), progesterone (P), testosterone (T), and prolactin (PRL), basically meet the clinician's needs for screening for endocrine disorders and general understanding of physiological functions.

The six-item sex hormone test has many tests that can detect many diseases. Therefore, as a common examination item, the six-item sex hormone test is a commonly used examination method for patients with endocrine disorders. Through the six-item sex hormone test, it can be determined whether the patient has endocrine diseases, and then the treatment method can be determined according to the test results.

The best time to check endocrine system is 3-5 days after menstruation. This period belongs to the early follicular stage and can reflect the functional status of the ovaries. However, for those who have not had their menstruation for a long time and are eager to know the test results, they can have the test at any time. The time will be taken as the time before menstruation, and the results will refer to the test results of the luteal phase.

The most accurate result is obtained by having a fasting blood test at 9 a.m. on the 3rd to 5th day after the onset of menstruation. For those who are infertile or have amenorrhea, or have not had menstruation for a long time, the examination can be done at any time, but it is best to do it on an empty stomach.

The inspection items are different and the attention methods are also different. The inspection content can be a full check or a single item check.

1. To check estrogen, progesterone, and follicle-stimulating hormone, 2 ml is required for each test, also after venous serum separation.

2. To check testosterone, 2 ml of venous serum is drawn. The commonly used method is radioimmunoassay, which can be measured after the serum is separated.

3. Prolactin should be checked on an empty stomach, with serum drawn around 9 a.m.

4. Check luteinizing hormone. Although it is also a radioimmunoassay test, because luteinizing hormone is secreted in a pulsed manner, it is best to collect samples 3-4 times within 1 hour and then mix them together for measurement, which is more accurate.

How do women check their estrogen levels? This test mainly involves blood tests. During the test period, patients should pay attention to rest and it is best not to work late at night, as this can easily lead to endocrine abnormalities, thus affecting estrogen levels. You cannot eat on the morning of the examination, and it is best to have a blood test on an empty stomach. After the examination, by observing six items of data, the level of female estrogen can be discovered, so that effective conditioning or treatment can be carried out.
