Having a blood test for progesterone has several meanings, mainly depending on what the purpose is. In infertility patients blood test progesterone is to understand the basic state of the ovaries, to see whether the progesterone is high or not, each hormone level is not normal, that is, sex hormone six. If progesterone is checked after pregnancy, it applies to patients with recurrent miscarriages before progesterone is measured. Progesterone testing is generally not advocated in people who do not have normal recurrent miscarriages. Even after pregnancy progesterone fluctuates widely over a 24-hour period and is a pulsatile secretion, so it is inaccurate and there is no need to check it. Some people have progesterone measurements, but it causes patients to be nervous, because the fluctuation is very large, sometimes measured in this time period just in the state of low values, so it is inevitable to cause cause panic. If the patient has a history of recurrent miscarriages, that is, spontaneous abortion or embryonic arrest more than 2-3 times of the population must pay attention to regular monitoring of progesterone levels, but also to include human chorionic gonadotropin and estradiol levels, you can check the sex hormone trio for evaluation, according to the lipid levels of the treatment of birth control. So look at what the purpose of a progesterone test is to know what it means.
