The results of the blood test to detect pregnancy are usually available within an hour. In early pregnancy, blood can be drawn to check chorionic gonadotropin, and if the results are significantly higher than the normal range, the pregnancy is considered to be a common biochemical test, and the results will be available in 30-60 minutes in most cases. During early pregnancy, the chorionic gonadotropin level can be monitored to determine the development of the fetus, because the HCG doubles daily during early pregnancy, and as long as the HCG doubles in a good state, the fetus is stable in most cases. If the HCG does not double or does not rise, it usually indicates that the embryo is not developing well and will have an abnormal or unavoidable miscarriage.
