Is there anything else I need to know about a pregnancy test?A urine pregnancy test shows whether HCG is present. HCG indicates pregnancy. A pregnancy blood test also shows the amount of HCG. If your blood tests show a very low amount of HCG, it could mean you have an ectopic pregnancy, a pregnancy that grows outside the uterus. A developing baby can't survive an ectopic pregnancy. Without treatment, the condition can be life-threatening for a woman.
