The progesterone test costs$60 and the HCG test costs$120. The blood is drawn from a pregnant woman’s vein, and no fasting is required during the test. The test results can determine early pregnancy and assist in the diagnosis of early intrauterine pregnancy and ectopic pregnancy. HCG has the properties of anterior pituitary follicle-stimulating hormone, luteinizing hormone, and has a high affinity for gonadotropin receptors, which maintain the corpus luteum and continue to maintain pregnancy. Progesterone is mainly produced by the ovaries in early pregnancy and from the placenta after 6-9 weeks of gestation. The main physiological functions of progesterone are: i. Reduce uterine muscle tone by inhibiting spontaneous contraction of uterine smooth muscle. Second, progesterone can co-operate with estrogen to stimulate the growth and development of mammary glands. Third, progesterone can also antagonize the effect of aldosterone on the kidneys and reduce the excretion of sodium in the urine of pregnant women.
