Re: do tubal pregnancies show up on pregnancy tests
There is always a hormone called HCG (human chorionic gonadotropin) that shows up in any pregnancy. Beta HCG is a very specific "marker" for pregnancy. This blood test is very sensitive and accurate in diagnosing pregnancy, even an ectopic (tubal) one. A positive HCG level confirms that you are definitely pregnant, but does not provide information about the site of your pregnancy... could be in your tube. A vaginal ultrasound can be used to determine the location of your pregnancy.
