Normal range of progesterone and hcg values ​​at 45 days of pregnancy

Progesterone is a type of pregnancy hormone secreted by female ovaries, which can maintain normal progesterone in the female body. The progesterone level in a woman's body will increase after pregnancy, but if the frequency of progesterone is too high, it will cause unnecessary troubles to the body. The most common one is the risk of miscarriage. Therefore, many expectant mothers are more concerned about their normal progesterone range. What is the normal range of progesterone and hcg values ​​at 45 days of pregnancy?

Progesterone and hcg values ​​comparison table

Progesterone is a pregnancy hormone secreted by the female ovaries. Progesterone in the female body is used to maintain the corpus luteum of pregnancy. Generally, women's progesterone levels will increase after pregnancy. HCG is also a substance that reflects pregnancy. The pregnancy period can be determined based on the progesterone or hCG value. Next, I will introduce to you the progesterone value and hcg comparison table.

On the 6th day after fertilization, the trophoblast of the fertilized egg is formed and secretes trace amounts of HCG. When the fertilized egg implants on the 7th to 8th day after fertilization, HCG can be detected in the blood, and its concentration increases exponentially with the increase in gestational age. Its amount is proportional to the number of trophoblasts. The secretion increases rapidly in early pregnancy, reaches a peak at 8-10 weeks of pregnancy, and then rapidly decreases to 10% of the peak value within 1-2 weeks. Therefore, it is difficult to judge threatened abortion or ectopic pregnancy based on the results of a single HCG test.

During normal pregnancy, the serum HCG value is directly related to the gestational age. The HCG (IU/L) value will certainly be different at different gestational ages, and will show a positive increasing trend. For example, 0.2-1 weeks of pregnancy, the HCG value is 5-50; 1-2 weeks of pregnancy, the HCG value is 50-500; 2-3 weeks of pregnancy, the HCG value is 100-5000; 3-4 weeks of pregnancy, the HCG value is 500-10000; 4-5 weeks of pregnancy, the HCG value is 1000-50000; 5-6 weeks of pregnancy, the HCG value is 10000-100000; 6-8 weeks of pregnancy, the HCG value is 15000-200000; 2-3 months of pregnancy, the HCG value is 10000-100000.

Progesterone levels are related to the outcome of early pregnancy. The serum progesterone levels of women with embryonic arrest and ectopic pregnancy are significantly lower than those of women with threatened abortion and normal early pregnancy. When progesterone is between 15 and 25 ng/mL, the pregnancy outcome is basically intrauterine pregnancy, but early threatened abortion is prone to occur. If the progesterone level is less than 15 ng/mL, the pregnancy outcome is often ectopic pregnancy or missed abortion. When progesterone is greater than 25ng/mL, the pregnancy outcome is mostly normal intrauterine pregnancy, and some have threatened abortion. Generally, after supplementing luteal function, the pregnancy can continue.

In short, changes in progesterone levels are a reliable indicator of whether corpus luteum function and placental development are normal. Since serum levels are stable in early pregnancy, continuous monitoring is not required, providing doctors with an early basis for diagnosis.
