Seven weeks of pregnancy belongs to the early stage of pregnancy, i.e. the first trimester, during which the normal reference value of progesterone is 4.73-50.74ng/ml.
Progesterone is an important progesterone hormone, mainly produced by the corpus luteum and the placenta, which can regulate menstruation and can also be used to maintain pregnancy. Among the normal progesterone values can vary at different times, such as a woman’s reference value of 4.73 to 50.74ng/ml in the first trimester of pregnancy, and 19.41 to 45.3ng/ml in the fourth to sixth month of pregnancy.
Tests for progesterone can be used to determine ovulation, progesterone therapy monitoring and early pregnancy status evaluation. Low progesterone may be the result of luteal insufficiency, preterm miscarriage, and so on.
The test report of progesterone is recommended to follow the clinician’s instruction whether supplemental progesterone treatment is needed, and take appropriate measures after clarifying the situation.
