Every pregnant woman knows that it is important to eliminate ectopic pregnancy in the early stages of pregnancy to ensure a healthy pregnancy. During the examination, it is necessary to conduct blood tests and combine them with abdominal ultrasound or vaginal ultrasound to confirm the possibility of ectopic pregnancy. So, how much blood can be drawn to rule out ectopic pregnancy?
When women undergo blood tests to exclude ectopic pregnancy in early pregnancy, it is not possible to determine and rule out ectopic pregnancy based on the amount of blood drawn. Instead, it is necessary to compare the HCG results of blood tests with normal reference values to preliminarily determine whether there are abnormal conditions in early pregnancy and the possibility of ectopic pregnancy. This test does not require a large amount of blood to be drawn. Generally, a blood sample of 2-5 milliliters can be taken to meet the needs of HCG testing.
If the examination finds that the secretion of blood HCG is not at the normal level in early pregnancy, and combined with the monitoring the next day, there is no good doubling growth, it is highly suspected to be an ectopic pregnancy. At around 40 days of pregnancy, if there is no gestational sac in the uterine cavity and a suspected gestational mass appears in other areas through ultrasound examination, combined with the results of these multiple tests, it can be diagnosed as ectopic pregnancy.
The blood hxg level in women during early pregnancy is at a normal level, and the next day there is a good doubling of growth. After ultrasound examination, it was found that there were gestational sacs and yolk sacs in the uterine cavity, which belong to the normal development level in early pregnancy. Therefore, ectopic pregnancy can be ruled out.
