Ectopic pregnancy hcg high or low

The hcg test cannot determine whether it is an ectopic pregnancy. Because the hcg values ​​for ectopic pregnancy and intrauterine pregnancy are the same. To diagnose ectopic pregnancy, you should first perform an ultrasound examination, which is also the best method of examination. B-ultrasound can detect the location of the gestational sac. We know that ectopic pregnancy is very harmful. It is an important cause of heavy bleeding and we must strictly prevent it from happening.

Ectopic pregnancy hcg high or low

The hCG value of ectopic pregnancy is the same as that of intrauterine pregnancy, because only the location of the fertilized egg implantation is different, and the early development of the fertilized egg is the same, so the HCG value in the blood and urine is the same.

The hcg value of ectopic pregnancy can be used to judge that it is a pregnancy reaction, that is, early pregnancy, but the hcg value cannot be used as a basis for the diagnosis of ectopic pregnancy. The diagnosis of ectopic pregnancy depends on the results of further examinations.

What is the range of hCG value for ectopic pregnancy? Diagnostic method: First, use B-ultrasound examination to determine the position of the gestational sac and check whether it is an ectopic pregnancy; second, test the hCG value again after two days. Under normal pregnancy conditions, the hCG value will double every two days, that is, after two days, your hCG value should be in the range of 500-1000, indicating that your embryo is developing normally and it is not an ectopic pregnancy; if the hCG value rises or falls slowly, the chance of ectopic pregnancy is relatively high and you should pay attention to it.

How to diagnose ectopic pregnancy

When ectopic pregnancy does not result in miscarriage or rupture, the clinical manifestations are not obvious, diagnosis is difficult, and auxiliary examinations are required for a confirmed diagnosis.

After miscarriage or rupture of ectopic pregnancy, diagnosis is usually not difficult. If there are difficulties, the changes in the condition should be closely observed. If there is continuous vaginal bleeding, aggravated abdominal pain, increased pelvic mass and a downward trend in hemoglobin, these will help to confirm the diagnosis. The following tests can also be used to assist in diagnosis:

1. hCG determination: Urine or blood hCG is crucial for the early diagnosis of ectopic pregnancy. In ectopic pregnancy, the hCG level in the patient's body is lower than that in intrauterine pregnancy. Continuously measure blood hCG. If the doubling time is greater than 7 days, the possibility of ectopic pregnancy is high; if the doubling time is less than 1.4 days, the possibility of ectopic pregnancy is extremely small.

2. Progesterone determination: The determination of serum progesterone is helpful in judging the development of the embryo in a normal pregnancy. In ectopic pregnancy, serum progesterone levels are low, mostly between 10-25ng/ml. If the serum progesterone value is >25ng/ml, the probability of ectopic pregnancy is less than 1.5%; if its value is <5ng/ml, intrauterine pregnancy abortion or ectopic pregnancy should be considered.

3. Ultrasound diagnosis: If no gestational sac is detected in the uterine cavity, but an abnormal low-echo area is detected beside the uterus, and the embryo and primitive heart tube pulsation are seen, ectopic pregnancy can be confirmed. If there is a mixed echo area and a free dark area in the uterine rectal fossa during parauterine exploration, even if no embryo or fetal heartbeat is seen, ectopic pregnancy should be highly suspected.

Combining blood hCG measurement with ultrasound examination is very helpful in the diagnosis of ectopic pregnancy. When blood hCG>2000IU/L and no intrauterine gestational sac is seen by vaginal ultrasound, the diagnosis of ectopic pregnancy is basically established.

4. Laparoscopic examination: Laparoscopic examination is the gold standard for the diagnosis of ectopic pregnancy, and laparoscopic surgical treatment can be performed at the same time as the diagnosis is confirmed. However, about 3%-4% of patients are missed due to the small gestational sac. They may also be misdiagnosed as a pregnancy due to the dilation and color change of the fallopian tube. This should be paid attention to.
