What method does threatened abortion check use

First: urine pregnancy test or determination of β - subunit level in blood: urine pregnancy test is positive: at 33-35 days after menopause, when the fetal sac is seen by transvaginal ultrasound, the level of β - subunit in blood is about 1800 mu / ml, which can reach 20000 mu / ml for a period of time. Lower than this value generally indicates poor prognosis.

Second: B-ultrasound examination: through vaginal B-ultrasound examination, fetal sac can be seen about 35 days after the last menstruation, and fetal primitive heart tube pulsation can be seen after 42 days; abdominal B-ultrasound examination, fetal sac can be seen 35-42 days after the last menstruation, and fetal primitive heart tube pulsation can be seen 49 days after the last menstruation.

In recent years, the determination of progesterone levels in blood is more accurate. If the serum progesterone level is lower than 5 ng / ml, whether it is intrauterine pregnancy or ectopic pregnancy, it generally indicates that the pregnant material has died. If the serum progesterone level is higher than 25 ng / ml, it indicates that the intrauterine pregnancy is alive. If the serum progesterone level is between 5 ng / ml and 25 ng / ml, it needs to be reexamined and followed up.
