What tests are needed for threatened miscarriage?

What tests are needed in case of threatened miscarriage? We can first discover threatened miscarriage from the symptoms, but if we want to proceed to the next step of treatment, we still need to do professional examinations according to medical procedures. So what tests are needed in case of threatened miscarriage? Let's learn about it through the article below.

1. Urine pregnancy test or determination of β-subunit levels in the blood: Positive urine pregnancy test: At 33-35 days after menstruation, when the gestational sac is seen by vaginal ultrasound, the subunit level in the blood is about 1800 milliunits/ml, and can reach 20,000 units/ml for a period of time. Values ​​below this generally indicate a poor prognosis.

2. Ultrasound examination: Through vaginal ultrasound examination, the gestational sac can be seen about 35 days after the last menstrual period, and the primitive heart tube pulsation of the fetus can be seen after 42 days; abdominal ultrasound examination shows the gestational sac 35 to 42 days after the last menstrual period, and the primitive heart tube pulsation of the fetus can be seen 49 days after the last menstrual period.

3. Determination of blood progesterone levels: Recent studies have found that the determination of blood progesterone levels is more accurate in judging the prognosis of pregnancy. If the blood progesterone level is lower than 5 ng/ml, whether it is an intrauterine pregnancy or an ectopic pregnancy, it generally indicates that the pregnancy has died. If the blood progesterone level is higher than 25 ng/ml, it indicates that the intrauterine pregnancy is alive; if it is between 5 and 25 ng/ml, reexamination and follow-up are required.

As the number of older mothers increases, the chance of threatened abortion also increases. There is no clear functional relationship between the two, but in clinical cases, it can be seen that there is indeed a correlation. At present, what should be done is to do a good job of prenatal examination during pregnancy, which is a respect for life and a responsibility for life.
