The progesterone test is a very important test for the hormonal background, especially for women planning a pregnancy. Doctors call it a hormone of pregnancy, since it is he who prepares the uterus for implantation of a fertilized egg and fixing an embryo for a successful pregnancy during the whole term. Also, this hormone prepares the woman's nervous system for pregnancy and maternity. The development of normal hormone progesterone favorably affects the development of the mammary gland, which is responsible for the production of milk for the baby.
Blood test for progesterone
The best demonstrative method of ovulation research is a blood test for progesterone. The level of progesterone, which will show an analysis of progesterone 17-OH, depends on the phase of the woman's menstrual cycle. The maximum level of progesterone is diagnosed in the luteal phase , as a rule, before ovulation it increases in more than 10 times. If this is not found, there is a reason for unrest and blood for progesterone must be re-administered.
When to donate blood to progesterone?
In case of malfunctions in the body, such as menstrual irregularity, weakness, uterine bleeding and others, you need to contact an endocrinologist or gynecologist-endocrinologist, who after consultation will give directions to the laboratory for hormone progesterone analysis. The result of the analysis on progesterone should not be decoded on its own, only a specialist in the laboratory can give the correct interpretation of the progesterone analysis - in each laboratory its indicators.
The most successful time for hormone progesterone analysis is the delivery of blood on the 22-23 day of the menstrual cycle. Blood must be given on an empty stomach (as well as all tests for hormones), after the last meal should pass at least 8 hours, you can drink water.
The reason for referring to the analysis for progesterone in pregnancy is anxiety about assessing the condition of the placenta in the second trimester of pregnancy, and also in order to diagnose the true detection of a delayed pregnancy.
