Ectopic pregnancy cannot be directly ruled out clinically simply by the progesterone value. Progesterone is lower than normal in ectopic pregnancy, but there is no fixed value.
Clinically, pregnancy is usually determined by blood or urine HCG, and the type of pregnancy is determined by ultrasound, which in turn determines the pregnancy. Often in ectopic pregnancies the embryo is poorly developed and HCG and progesterone values may be low, but this is not absolute. In normal pregnancies, the embryo may stop developing and the HCG and progesterone values may be low.
Therefore, as ectopic pregnancy cannot be ruled out directly by HCG and progesterone values, it is recommended that pregnant women who suspect an ectopic pregnancy should seek medical attention in time for an ultrasound examination, and if the gestational sac can be seen inside the uterine cavity during the ultrasound examination, the pregnancy is considered to be normal. If it is outside the uterine cavity, the possibility of ectopic pregnancy is higher.
If a pregnant woman experiences symptoms of suspected ectopic pregnancy such as unilateral lower abdominal pain and abnormal vaginal bleeding during pregnancy, she needs to seek timely medical attention.
