In brief: Depends on gest age

The blood pregnancy test or beta HCG is very sensitive and specific.
The hormone is produced only by a developing human pregnancy. However, one result is only a snapshot. A very early pregnancy could be normal, not normal or possibly an ectopic pregnancy. Sometimes it is necessary to check the levels over several days to discern how the pregnancy is going.
