Do I need to fast to check progesterone? Is it the decisive factor?

Progesterone is a progestin hormone. The progesterone value in women is different at different stages of pregnancy, and the progesterone value can be checked. Many people want to know whether they need to fast to check progesterone. Generally speaking, most tests require fasting, but there is no direct relationship between progesterone and fasting.

1. Progesterone test does not require fasting

The progesterone test is conducted by drawing venous blood from the pregnant mother. Since the progesterone content is not affected by eating, the progesterone test does not require fasting, and the mother can drink water during the test. Generally, after the examination in the morning, the results can be obtained in the afternoon.

During the entire menstrual cycle of a normal non-pregnant woman, the progesterone level is very low before ovulation, begins to rise after ovulation, and is very high during the luteal phase. Before ovulation, the progesterone level in body fluids should be less than 2 ng/mL, and after ovulation it should be greater than 5 ng/mL. If you become pregnant, the progesterone level will initially remain at the level of the luteal phase. After the placenta is formed, the hormones secreted by the placenta will increase the progesterone level in the body to 100-200 ng/ml, which is dozens to hundreds of times that of non-pregnant women. Hence the name progesterone.

2. Fasting is not a decisive factor

Progesterone, also known as progesterone, progesterone, progesterone, progesterone, progestin, progestin or progesterone, is a steroid involved in female menstrual cycle, pregnancy and affects the embryos of humans and other animals. Progesterone test is mainly used to understand the function of the corpus luteum and whether the ovaries ovulate. Progesterone testing is best done on an empty stomach. Venous blood is drawn for examination. Due to the special effects of food, which can cause changes in serum hormone levels in the body, it is generally necessary to fast before doing a blood analysis so that the test results can be accurate.

3. Pay attention to normal values

Generally, when the progesterone level is lower than the normal value, it is necessary to increase the progesterone level to reach the normal value. Conversely, high progesterone directly affects the growth of women's follicles and ovulation.

Progesterone is a type of progestogen, which is a naturally secreted progestogen in the human body. Progesterone has a negative feedback regulatory effect. It can inhibit its own secretion and also inhibit the secretion of estrogen. The main function is to determine whether the ovaries have ovulated and to understand the function of the corpus luteum. If the progesterone level is low, miscarriage is likely to occur. For unmarried women, low progesterone may lead to infertility in the future.
