Patient's question:
Hello doctor, I recently found out I'm pregnant, as confirmed by a pregnancy test strip. I suddenly had an idea and wanted to ask you, could an ectopic pregnancy show a positive result on a test strip? If the blood draw is unsuccessful, what methods can be used to determine the situation? Is the result from a test strip accurate?Doctor's answer:
Early pregnancy tests mainly detect pregnancy by measuring the level of hCG in the body. They cannot be used to distinguish between intrauterine pregnancy and ectopic pregnancy, as both can show positive results in early pregnancy tests. The most accurate test for ectopic pregnancy is ultrasound, but it can only be identified around 45 to 50 days of pregnancy. In early pregnancy, blood tests to check hCG and progesterone levels can help distinguish ectopic pregnancy, as the hCG and progesterone levels in ectopic pregnancy are significantly lower than those in normal pregnancy.
