Is the estrogen test a blood test?

Female estrogen tests are generally done through blood draws, and need to be done 3-5 days before menstruation, preferably on the third day of menstruation, and the test must be done on an empty stomach. Estrogen is very important for women. If estrogen is abnormal, women's menstruation and fertility will also be affected. Therefore, everyone must pay attention to it.

What are the specific contents of the 6-item estrogen test?

1. Follicle-stimulating hormone (FSH):

Promote the development and maturation of ovarian follicles. Normal values: 1.5-10mIU/ml in the preovulatory period, 8-20mIU/ml in the ovulatory period, and 2-10mIU/ml in the postovulatory period.

2. Luteinizing hormone (LH):

It promotes ovulation, forms a corpus luteum and secretes progesterone. Low FSH values ​​are seen during estrogen-progestin treatment, etc. Normal values: 2-15mIU/ml in the preovulatory period, 30-100mIU/ml in the ovulatory period, and 4-10mIU/ml in the postovulatory period.

3. Prolactin (PRL):

It is a simple protein hormone that promotes breast hyperplasia, milk production and milk discharge. Normal value: During the non-lactation period, the normal value of blood PRL is 0.08-0.92nmol/L. A level higher than 1.0 nmol/L is considered hyperprolactinemia.

4. Estradiol (E2):

It promotes the transition of the endometrium into the proliferative phase and the development of secondary sexual characteristics. Normal value: The concentration of blood E2 is 48-521nmol/L in the preovulatory period, 70-1835nmol/L in the ovulatory period, and 272-793nmol/L in the postovulatory period, indicating premature ovarian failure and Sheehan's syndrome.

5. Progesterone (P):

It promotes the transition of the endometrium from the proliferative phase to the secretory phase. Normal value: Blood P concentration is 0-4.8nmol/L before ovulation and 7.6-97.6nmol/L in the late ovulation period, which is seen in luteal insufficiency, ovulatory dysfunctional uterine bleeding, etc.

6. Testosterone (T):

About 25% of adrenal cortex secretion comes from the ovaries. Promote the development of the clitoris and mons pubis. Normal value: The normal concentration of T in female blood is 0.7-3.1nmol/L. High blood T value can cause infertility.

Estrogen test method:

1. Draw blood.

2. Testing.
